Stone waste (SW) from the dimension stone industry has physical and chemical characteristics with great potential for use as an alternative raw material in several industrial activities. Its main constituents include silica, alumina, alkaline, and alkaline earth oxides, usually combined as calcite and dolomite in the crystalline phases. In this work, a case study was conducted with SW from a processing plant of dimension stones (also known as ornamental rocks) located in Viana do Castelo, Portugal. In this new methodology, the SW powder samples were characterised by Xray fluorescence spectrometry, X-ray diffraction, differential thermal analysis, and thermogravimetry. Physical features, such as moisture content, specific surface area, particle size distribution, and true density were also determined. The pH and electrical conductivity of the SW as a suspension were also evaluated. The specific SW was analysed against the literature considering aspects related to environmental legislation and standards (waste classification), physical and chemical characteristics (potential), production data (quantity), recycling avail­ ability (viability), and market opportunities (applicability). This novel way in terms of the form and content of a paper is an intermediate approach between an original article and a state-of-art review. SW is normally considered inert but, owing to its high fineness (<200 μm), some potentially hazardous compounds can been leached. The state-of-the-art of SW applications suggests that this waste is promising raw materials for ceramics and cement, which eventually encapsulate contaminants in their structure. A critical discussion of the literature was conducted to reduce the knowledge gap about the most promising valorisation strategies for SW. New recycling proposals are also suggested.

Introduction Considering the population increase over the last decades (from 3 to 7.8 billion people between 1960 and 2020), followed by growing ur­ banisation (from 34 to 56% in the same period) (Worldometer, 2020) and the industrial processes of modernisation, the global waste gener­ ation per capita is growing exponentially. In the USA alone, each citizen produces an average of 808 kg of waste per year (Sensoneo, 2020). It is estimated that 90% of the raw materials used for manufacturing durable products become waste even before the product leaves the factory * Corresponding author.

Journal of Cleaner Production 319 (2021) 128678 (industrial waste), and approximately 80% of the finished product is discarded within the first six months of its use (municipal waste gen­ eration) (Arts, 2013). A report by the World Bank (The World Bank, 2018) estimated that global waste production is predicted to increase by 70% by 2050 unless urgent action is taken. Indeed, waste recycling is one of the most discussed issues in the 21st century and is the subject of thousands of academic papers. There are essentially three ways of dealing with inorganic waste, namely, reuse, recycling, or disposal in landfills. Reuse and recycling are the preferred waste management methods that consider environmental sustainability and the opportunity to generate important economic returns. Reuse means to use by-products with the same purpose for which they were conceived, while recycling is related to material val­ orisation in other processes, by converting waste into new materials. However, consolidating a sustainable waste management process re­ quires investments and long-term efforts, which is the main reason why disposal to landfills is the most widely used approach, especially in economically fragile countries. Even when local governments manage waste through regulations, laws are not always followed, and poorly managed waste continues to contaminate the environment and adversely affect animals and humans. The proposal and consolidation of a recycling process begin with a case-by-case examination by considering the physical and chemical characteristics of the waste. Many wastes have chemical and mineral­ ogical compositions remarkably like those of traditional raw materials, allowing industries to earn environmentally friendly seals by using these wastes as feedstock in their manufacturing processes, thus reducing the costs of the final products. This work presents and discusses the potential and the challenges of recycling stone waste (SW) generated from a processing industry of dimension stones (also known as ornamental rocks), using a new waste valorisation systematic (detailed in section 3). The SW characteristics depend on the composition of the original stones. Marble and granite are the most used, and its main constituents include silica, alumina, alkaline and alkaline earth oxides (Segadães et al., 2005), usually in the crys­ talline forms of calcite and dolomite in the case of marble, as well as quartz, feldspar, and mica, corresponding to granite (Acchar et al., 2006; Uygunoğlu et al., 2014). Despite the promising physicochemical SW features with great potential for use as raw materials in other industrial sectors (Tugrul Tunc, 2019), landfills are still its main SW destination. The countries that extract and process dimension stones, and consequently generate larger SW quantities, are in the following order: China, India, Turkey, Iran, Brazil, and Italy (ABIROCHAS, 2018a; Montani, 2019). In most Middle Eastern and Mediterranean countries, dimension stone processing is the main source of economic revenue. In Palestine, this industry represents approximately 34% of the national income (Abu Hanieh et al., 2014). Major importers, including the USA, South Korea, Germany, and Canada, also generate large SW quantities (ABIROCHAS, 2018a; Demirel and Alyamaç, 2018). Although many published studies highlighted the SW characteristics and recycling potential as alternative raw materials in other industrial processes (as will be reported in Section 7), SW remains unknown in most industries. As a large part of the waste generated comes from small companies scattered in urban centres, there is not always an inspection for the correct handling, especially in emerging cities. In this sense, nonhazardous SW are impacting the air, soil, and water (Davini, 2000; Demirel and Alyamaç, 2018; Ercikdi et al., 2015). The main reasons behind these current management practices (landfilling) are discussed in this study. The present work provides the most detailed characterisation of SW, as a case study, including chemical, physical, thermal, and microstruc­ tural analyses, and discusses the main applications, including cementi­ tious materials and ceramic formulations, as well as less conventional recycling proposals, such as alternative binders, environmental appli­ cations, filler in industrial products including paints, paper, rubber, and reinforcement for polymeric matrices (Careddu et al., 2014). This methodology is an intermediate approach between an original article and a state-of-art review, which consists in a novel way in terms of the form and content of a paper. It is worth mentioning that there are some published reviews on SW recycling covering different technical aspects of this waste, especially focusing on building materials, such as mortar and concrete (Rana et al., 2016; Rodrigues et al., 2015; Şahan Arel, 2016; Singh Chouhan et al., 2019; Singh et al., 2017a; Thakur et al., 2018; Tugrul Tunc, 2019). Nevertheless, few studies suggest alternative applications (Careddu et al., 2018; Mehta et al., 2016; Tozsin et al., 2015). However, even with literature showing varied recycling solutions for SW, landfills are still its main destination. In this sense, this work gathers the knowledge of the most relevant publications to address and discuss the accurate SW recycling potential, which includes the characterization of the waste followed by a critical analysis of the feasibility of the proposed appli­ cations. Novel recycling proposals for future work are also suggested. 2. Dimension stones processing and generated waste There is a wide variety of dimension stones with different shapes and shades originating from a variety of igneous, metamorphic, and sedi­ mentary rocks. These rocks are commonly known as marble, granite, limestone, travertine, quartz-based stone (sandstone, quartzite), and slate. Alyamaç and Aydin (2015) and Sarkar et al. (2006) proposed classifying them into two general categories, namely, i) polished stones, including, marble (metamorphic rock) and granite (igneous rock), the most popular, as well as travertine and onyx; and ii) unpolished stones, such as basalt (although some polishable basalts run away from this classification, as noted in Careddu and Grillo (2019)), schist, and tuff. Differently, Careddu et al. (2016), proposed classifying them into three main groups, i) marbles (carbonate stones as real marbles, mostly calcite and dolomite-based); ii) granites (silicate stones as real granites, mostly quartz and alkali feldspar-based); and iii) other stones such as basalts (igneous), trachyte (igneous) and sandstones (sedimentary). This work is focused on marble and granite stones, which are by far the most produced dimension stones currently. The production process of these stones normally comprises main stages, such as prospecting, quarrying, transportation, cutting/sawing, and finishing (polishing, flaming, bush-hammering) (Careddu and Dino, 2016). Stones are extracted in the form of blocks and sent to sawing and polishing plants. After sawing to a previously defined size and thickness, the stones are polished, cleaned, and shined. A large amount of water is used in all processing steps (see Fig. 1) to prevent overheating of the cutting and polishing discs and to reduce the incidence of dust (Alyamaç and Aydin, 2015; Demirel and Alyamaç, 2018; Ulubeyli and Artir, 2015), resulting in large amounts of effluents in the form of sludge (Demirel and Alya­ maç, 2018), which will be referred to hereinafter as stone waste (SW). Settling tanks and filter presses can be used to remove water and reduce the volume of sludge generated (Torres et al., 2009). In some industrial plants, it is also common to store the generated sludge in open or closed settling dams for weeks. In this case, the suspended particles settle down, and water slowly evaporates, increasing the solid concentration in the sludge. 3. Materials and methods The CPQvA (Classification, Potentiality, Quantity/Viability and Ap­ plications) valorisation system (Oliveira, 2017; Raupp-Pereira et al., 2006, 2007) was adopted in this work (Fig. 2) in the context of recycling potential of stone processing plant wastes. It is divided into SW col­ lecting and characterizing; classification according to hazardousness and potentiality, besides addressing aspects related to their quantity and possible applications, seeking the best SW destination. This waste recovery analysis methodology suggests carrying out a complete analysis of the waste characteristics prior to the design of the recycling solution. Therefore, this work initially brings a detailed 2 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 Fig. 1.

CPQvA stands for Classification, Potentiality, Quantity/viability and Applications. characterization of a SW and the production data (items Classification, Potentiality, Quantity, and Viability). The experimental findings are compared with literature data, such as an original article, while in the subsequent sections the recycling proposals viability was validated by using available literature studies, such as a state-of-art review (item Applications). days. The stones processed by the company are composed of marble (~80 wt%) and volcanic stones (~20 wt%). The samples were dried at 110 ◦ C for 24 h and sieved #200 (74 μm) for deagglomeration. The SW powder samples were characterised by X-ray fluorescence spectrometry (XRF, Philips X’Pert PRO MPD spectrometer) with the loss on ignition (LOI) determined at 1000 ◦ C. X-ray diffraction (XRD, Bruker D8 Advance DaVinci equipment with Cu Kα radiation) was applied in the range of 5–80◦ , with steps of 0.02◦ and 0.5 s/step and the diffraction patterns were analysed using the ICDD database (International Centre of Diffraction Data, PDF 4) in the EVA software (Bruker). Differential thermal analysis (DTA) and thermogravimetry (TG) were performed ◦ using a simultaneous thermal analyser (402 EP, Netzsch) at 10 C/min 3.1. Materials and characterisation Three SW batches (SW1, SW2, and SW3) were collected from different bags from the deposit of dimension stones (ornamental rocks) sawing and polishing plant located in Viana do Castelo, Portugal, on random 3 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 4. Classification and environmental impacts up to 1000 ◦ C under an air atmosphere. Physical features, such as moisture content, specific surface area by N2 adsorption (Brunauer–Emmett–Teller; Gemini 2380, Micromeritics), particle size distribution (laser diffraction, Coulter LS230 analyser), and true density (Helium pycnometer, Multipycnometer, Quantachrome), were also determined. Finally, the pH (Hanna HI8424) and electrical conductivity (HACH 44600) of the SW suspensions were evaluated by adding 5 g of powder to 50 mL of deionised water, followed by manual stirring for 5 min. The analyses were conducted after 10 min and according to the procedure adopted by Davidovits (2008). Waste is managed according to the regulations of the country in which they are generated. In the USA, hazardous and non-hazardous solid waste must follow the Environmental Protection Agency (EPA) recommendations. According to the EPA, “hazardous waste is hazardous or potentially harmful to our health or the environment” (EPA-USA, 2020). The EPA monitors eight heavy metals that are extremely toxic, even at low concentrations (Table 1), and has set limit concentrations for As (5 mg/L), Ba (100 mg/L), Cd (1 mg/L), Cr (5 mg/L), Pb (5 mg/L), Hg (0.2 mg/L), Se (1 mg/L), and Ag (5 mg/L) (EPA-USA, 2012). These el­ ements, when present in lakes, rivers, or soil, may be harmful to the environment, affecting fauna and flora. Table 1 lists the quantifications of the main metals present in the three SW samples studied in this work, and for comparison, some typical compositions of granite and limestone rocks, according to Alloway et al. (2010). As shown, among the EPA-monitored elements, the referred amounts of Ba, Cr, and Pb commonly found in SW samples could be higher than the legal limit. In this sense, the species’ leachability will ultimately dictate the real environmental impact of SW. Despite this, the naturally occurring heavy metals are expected to show poor leachability. The European waste catalogue (EPA-EU, 2002) classifies waste from mining and sawing dimension stones as code 01 or “wastes resulting from exploration, mining, quarrying, and physical and chemical treat­ ment of minerals”; and sub code 01 04 or “wastes from physical and chemical processing of non-metalliferous minerals.” These codifications include cut waste, gravel, crushed rocks, dust, and other unspecified forms (Careddu and Siotto, 2011; Dino et al., 2015; EPA-EU, 2002; Rana et al., 2016). As natural stones are considered inert materials (non-hazardous) for most applications, despite the significant presence of some hazardous elements, SW has also been considered inert, as it contains metals in similar proportions to the original stone (Al-Zboon et al., 2010; Rana et al., 2016). It has been overlooked that these ele­ ments can be incorporated during the extractive and processing opera­ tions (Karaca et al., 2012; Rana et al., 2016). Indeed, because of the false idea that these materials are non-hazardous, incidents of soil and ground/surface water contamination have been documented (Tabelin 3.2. Databases and search methodology Extensive research was conducted using Scopus, Web of Science, SciFinder, Scielo, Springer, and Wiley databases, and papers filtered using the following keywords: “stone cutting waste”, “stone sawing waste”, “marble waste”, “marble powder sludge”, “marble sludge waste”, “marble dust”, and “stone and marble sector”. The most cited and recent articles were thoroughly evaluated according to the defined analysis criteria CPQvA. This systematic method is guided by five decision-making criteria, namely, classification, potential, quantity, viability, and applicability, considering aspects related to environmental regulation and standards (classification), physicochemical characteris­ tics and purity (potential), production data (quantity), recycling chal­ lenges (viability), and market opportunities (applicability). This systematic guide is a simple and useful tool for investigating the recy­ cling potential of industrial wastes, as adopted by authors in previous studies (Oliveira, 2017; Raupp-Pereira et al., 2006, 2007, 2007; Simão et al., 2018; Souza et al., 2019). Other references, including environ­ mental laws and regulations (ABNT, 2004a, 2004b; EPA-USA, 2012; European Union, 2008), books (Alloway, 2010; Davidovits, 2008), and websites (ABIROCHAS, 2018b, 2018a; Worldometer, 2020) have also been used to include economic and environmental aspects. The envi­ ronmental law was used to compare the legal limits of metals in SW and classify them concerning their real hazardousness.

After leaching tests in water. 4 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 et al., 2018). In Europe, leaching tests are performed to guide the classification of wastes as inert, hazardous, or non-hazardous, according to the Landfill Directive and Council Decision 2003/33/EC (European Union, 2008). The leaching simulation tests may be conducted in different ways, that is, through a double-stage leaching process, where the first step is per­ formed at a liquid to solid ratio (L/S) equal to 2 and then at L/S = 8 (this procedure mimics the natural conditions of leaching by rainwater for materials with a high solid content). The second step follows an up-flow percolation test at low L/S ratios (simulating behaviour in disposal scenarios). Alternatively, a single-stage leaching process can be applied with L/S = 10. The latter procedure is the most common. The European leaching limits are more rigorous than those from the EPA-USA, with more elements being monitored. In other countries, such as Brazil, which follows specific standards (ABNT NBR 10004/2004), industrial wastes are classified into three classes, namely, hazardous (Class I) when corrosive, pathogenic, flam­ mable, or toxic characteristics are present; non-hazardous but non-inert (Class II-A), when biodegradability, combustibility, or water solubility is demonstrated; and non-hazardous and inert (Class II-B) when none of the previously cited characteristics are demonstrated (ABNT, 2004a). The Brazilian standard establishes limit concentrations for several compounds (Table 1) determined by leaching tests according to ABNT NBR 10005/2004 (ABNT, 2004b). These include Cr, Ba, and Pb, which are common in SW. If the limits of these elements exceed 5, 70, and 1 ppm (or mg/L), respectively, the waste is considered hazardous (Class I) (ABNT, 2004b). This study did not perform leaching tests on the samples in compli­ ance with the American, European, or Brazilian regulations. However, the literature shows that the data are sufficient for the proposed objec­ tives. Hameed and Sekar (2009) characterized a sludge predominantly composed of granite-based stones from Indian factories and noticed the presence of barium (12 mg/L), chromium (1.2 mg/L), lead (0.9 mg/L), minor contents of arsenic (0.5 mg/L), and cadmium (0.3 mg/L), all within acceptable limits. Dino et al. (2015) reported that when the cutting and polishing steps were conducted using a gang saw, Cr (166 ppm), Cu (188 ppm), and Zn (76 ppm) were the main leached species, probably because of cutting disc abrasion and wear and the cleaner water jet. When diamond saws are used, the elements commonly detected are Zn (99 ppm), Co (89 ppm), and Cu (24 ppm) (Dino et al., 2015; Rana et al., 2016). Tabelin et al. (2018) discussed the presence of heavy metals in debris excavated from tunnels and other large infrastructure projects in megacities. According to these authors, substantial portions of the excavated debris are often naturally contaminated with hazardous ele­ ments, which are readily released in substantial amounts once exposed to the environment. This contaminated excavation debris is loosely referred to as “naturally contaminated rocks”. They can contain several hazardous and toxic inorganic elements, such as As, Se, B, and heavy metals such as Pb, Cd, Cu, and Zn. If not properly treated, these naturally contaminated rocks can cause severe problems to the surrounding ecosystems. Simsek et al. (2005) studied the effects of marble waste disposal on the water and sediment quality in the district of Torbali, Izmir, Turkey. According to the authors, approximately 35000 tons of marble waste was disposed of on the riverbed in a single year (2005). They reported an increase in the number of ions present in the water (mainly Ca and Mg) and sediments, resulting in highly turbid water. The authors also noticed traces of Fe, Al, As, and Pb in sufficient amounts to compromise the quality of the drinking water (Simsek et al., 2005). Çelik and Sabah (2008) also reported a high concentration of solubilised Ca, Mg, and Cl in wastewater from marble processing. From an environmental perspective, the increased turbidity of wa­ tercourses can reduce light penetration, consequently, decreasing photosynthesis and the reproduction of organisms, reducing nutrients, modifying the food chain, and threatening aquatic biodiversity (Khyaliya et al., 2017; Torres et al., 2009). Consistent with these ob­ servations, some studies have highlighted the mutagenic effects of or­ ganisms exposed to SW effluents. Aguiar et al. (2016) evaluated the mutagenic effect of SW on onion root cells and fish erythrocytes. The authors concluded that the analysed waste had mutagenic potential under the studied conditions (Aguiar et al., 2016). Venturoti et al. (2019) evaluated the toxic effects of SW effluents on Geophagus brasi­ liensis and highlighted the toxic effects of the waste on these organisms. The problems associated with the extraction, processing, and improper disposal of SW can affect water, soil, and air (Abu Hanieh et al., 2014; Careddu and Siotto, 2011; Yavuz Çelik and Sabah, 2008). In quarries, extraction pollutes the air with the generated dust, in addition to the excavations, which have a strong impact on the soil and land­ scape. In the stone sawing industry, dust is partially mitigated by adding water to the process, but it generates another problematic waste, namely, the sludge in the settling dams (Abu Hanieh et al., 2014). Another environmental impact related to this activity is the trans­ portation of these materials, which generates emissions from fossil fuel combustion, in addition to dust (Abu Hanieh et al., 2014). Because of its high fineness, the presence of SW (Alyamaç and Ince, 2009) can result in excessive soil compaction, occupying voids, preventing water percola­ tion, and reducing fertility (Khyaliya et al., 2017). Therefore, the safe disposal of heavy metal-containing solid wastes, such as SW, is a chal­ lenging task. The numerous environmental concerns associated with the dimen­ sion stone sector can be remedied in several ways (Abu Hanieh et al., 2014; Careddu and Siotto, 2011), such as separation and treatment of the waste before deposition (Table 2) or reusing it in new applications. If the waste has leachable elements, it is important to use it in materials able to encapsulating them. Thus, the waste can provide social and economic benefits. The immobilisation of metal elements in cementi­ tious materials and through thermal treatments are examples of encapsulating techniques in a certain structure through physical and chemical processes (Guo et al., 2017). The potential applications are broadly discussed in section 7. 5. Potentialities: chemical and physical features As previously reported, the physical and chemical characteristics of the SW are mainly dependent on the original stones, with marble and granite being the most common. Accordingly, it is advisable to start by investigating the chemistry of these stones. Marble is a crystalline metamorphic limestone resulting from the recrystallisation of limestone (CaCO3) and dolomite (CaMg(CO3)2) at high temperatures and pressures (Demirel and Alyamaç, 2018; Segadães et al., 2005). It contains large amounts of calcium carbonate (CaCO3) and minor impurities, such as silica, feldspar, iron oxides, mica, fluorine, and organic matter (Acchar et al., 2006; Uygunoğlu et al., 2014). Granite is an igneous stone mainly composed of minerals such as feldspar, quartz, and mica (Segadães et al., 2005; Vieira et al., 2004), and its main constituents are silica, alumina, calcium oxide, and alkaline oxides (Segadães et al., 2005). Because of the chemical composition differences Table 2 Main impacts and remediation practices of the stone cutting and polishing industry.

Simão et al. Journal of Cleaner Production 319 (2021) 128678 between the stones, the sludge composition will vary in the processing plants, depending on the amount of marble or granite-based stones processed, according to stone availability and customer demand. Fig. 3a shows the X-ray diffractograms of the SW samples used in this study. In the SW1 and SW2 patterns, calcite (JCPDS card 01-085-1108) predominates, whereas, in SW3, calcite has a leading role with dolo­ mite (JCPDS card 00-036-0426). This is because the SW samples in this study were mainly derived from marble stones (~80 wt% of stones processed) with variations in the carbonate content. The XRD patterns are aligned with the chemical composition of the samples, as shown in Table 3. In SW1 and SW2, large amounts of CaO (50.59 and 46.48 wt% respectively) and a high LOI (~36 wt%) were identified. In SW3, in addition to the CaO (~42 wt%), a significant concentration of MgO (~10 wt%), from the dolomite phase (CaMg (CO3)2), was detected. The effect of temperature on SW (only for SW1) was investigated using DTA/TG analysis (see Fig. 3b). The decomposition of carbonates (endothermic event E3) was initiated at approximately 700 ◦ C and was observed up to approximately 970 ◦ C. The thermal decomposition of pure CaCO3 usually does not exceed 800 ◦ C (Karunadasa et al., 2019; Souza et al., 2017), but the presence of a very low percentage of alkali salts can modify the decomposition range. For example, for CaCO3 with 1% NaCl, thermal decomposition ranges from 700 to 975 ◦ C (Chattaraj et al., 1973). Chlorides were not detected in the samples considered here (by XRF) but were detected by Yavuz Çelik and Sabah (2008) in marble sludge water. Other thermal events identified in SW are those resulting from the evaporation of the adsorbed and combined water between 20 and 250 ◦ C (endothermic event, E1) and the combustion of polymeric resin and other organic waste materials from the cutting and polishing processes, between 300 and 500 ◦ C (exothermic event E2). The presence of poly­ meric resin in the sludge depends on the SW generation process of each industry. In this case, honeycomb-like Al sheets were bonded with epoxy-based glue on the stone surfaces before sawing (see Fig. 4). The main purpose is to obtain thinner stone slabs than traditional ones (~6 mm), reduce the weight of the stone, and maintain mechanical properties. The particularity of this company to introduce other mate­ rials (Al sheet and glue epoxy) to the process may be responsible for the small compositional differences in the waste generated. This becomes important for certain applications, as it can change the properties of the material obtained, even at low concentrations. To date, few studies evaluated the variations in the chemical composition of the SW, the exception being the works of (Careddu et al., 2014; Careddu and Marras, 2015). The majority of studies consider that the chemical heterogeneity can be mitigated by storing them in big lots. Table 3 lists the chemical compositions of the SW samples. As seen, the chemical characteristics of the sludge depend on the original stones processed. The chemical compositions of the SWs collected from various literature studies are provided for comparison. The results show that the main oxides presented are referred to as marble and granite stone wastes (Table 3). When waste is mostly derived from marble stones, the main minerals present are calcite and occa­ sionally dolomite, and the chemical compositions are remarkably similar. Magnesium oxides and silica are the main secondary com­ pounds. The Mg mass content depends on the limestone deposit, which can be classified into three types, namely, calcitic limestone when the MgO content is less than 5%, dolomitic limestone if the MgO content is between 5 and 12%, and magnesian limestone when the MgO content exceeds 12% (LaborSolo, 2020). This limestone type classification is important for waste applications in the soil to supply the Ca or Mg deficiency. When waste is not derived from marble stones, the minerals present are heterogeneous, with several crystalline phases such as quartz, mica, kaolinite, feldspar, anorthite, and marble waste (calcite and dolomite). The chemical composition reveals the presence of SiO2 and Al2O3 as the main oxides, with other minorities dependent on the composition of the cutting stone (Table 3). Table 4 lists the main physical features of SW1 as compared to the literature. The moisture content of the three SW batches varied between 22 and 27 wt%, and the true densities between 2.4 and 2.9 g/cm3, near to the theoretical densities of the main minerals present in the samples, calcite (2.71 g/cm3) and dolomite (2.84 g/cm3). The SW particle size distribution ranged from 3.4 to 200 μm (Fernández-Caliani and Barba-Brioso, 2010; Kabas et al., 2012; Sarkar et al., 2006; Tozsin et al., 2014a) and the specific surface area ranged from 0.2 to 2.5 m2/g (Demirel and Alyamaç, 2018; Rana et al., 2016). The high fineness is especially related to the polishing and sawing processes (Demirel and Alyamaç, 2018). Likewise, Fig. 5 shows the SW1 particle size distribution, revealing that 100% of the particles were below 40 μm. The medium alkalinity shown in Table 4 is associated with the presence of carbonates, ranging from pH 8.1 to 9.6. Incidentally, this alkalinity might favour recycling in some applications, such as in geo­ polymers, which are an eco-friendly alternative to Portland cementderived binders. Previous studies have shown that under alkaline con­ ditions, calcite is thermodynamically unstable, and thus highly reactive (Locat et al., 1991; Palmero et al., 2017). Indeed, pH is an important parameter that triggers the alkaliactivation process in these materials, driving the hardening process for pH ranges between 8 and 11 or even flash-setting when the pH exceeds Fig. 3.

As the SW1 sample reached pH > 8 (after 10 min of contact with water), it might be a potential candidate to accelerate the geopolymerization reactions. Nevertheless, the chemical composition of SW must also be considered to enable it to be used as a reactive precursor in the synthesis of geopolymers (or alkali-activated materials). The required presence of reactive silica and alumina is dependent on the stone origin, that is, marble-derived stones typically contain fairly low amounts of SiO2 and Al2O3, while granite contains significant amounts of these oxides. Therefore, the chemical composition of granite-based stones is more suitable for the envisioned applications. Additionally, calcite dissolution might promote the acidity neutral­ isation of effluents, water, and soils, as demonstrated by Equation (1), which has been reported for many applications (Ercikdi et al., 2015; Fernández-Caliani and Barba-Brioso, 2010). CaCO3 + H2 O ↔ Ca2+ + HCO−3 + OH − (1) These ions drive the electrical conductivity values (Table 4) for the SW1 sample and SW, as reported by Kabas et al. (2012). Therefore, the SW recycling potential depends on its chemical and physical characteristics. As previously mentioned, the SW chemical composition depends on the heterogeneity of the stones processed dur­ ing different periods and their mineralogy. When the chemical compo­ sition is heterogeneous, applications are restricted to the physical potential of the SW by exploring their fineness, especially as a filler in the mortar and concrete formulations. When the chemical composition is homogeneous, SW can be exploited as a source of CaCO3 and/or magnesium carbonate. Section 7 discusses the main applications pro­ posed in the literature. 6. Quantity and viability: generation data and disposal costs The global production of dimension and coverings stones increased from 1.8 Mt/year in the 1920s to 153 Mt/year in 2018. The production values between 2014 and 2018 (see Table 5) show an increase of approximately 12% within this period (from 136.5 to 153.0 Mt). In 2019, it was estimated that these numbers also exceeded 100 Mt (Careddu, 2019). China, India, Turkey, Iran, and Brazil (ABIROCHAS, 2018a; Montani, 2019) are the largest producers globally. China contributed 31.4% of global production in 2018, reaching absolute values of ~48 Mt of dimension stones. In 2017, this sector negotiated at US$ 20.6 billion globally, of which US$ 5.0 billion corresponded to Brazil (ABIROCHAS, 2018a, 2018c). Brazil was the fourth-largest producer in 2014, 2015, and 2016, being overtaken by Iran in 2017 and 2018 due to the gradual, but steady, increase in stone production in this country over the recent years (Table 5). The production of dimension stones in Portugal, where the SW samples were collected, reached ~3 Mt in 2018, occupying a ninth place among the largest global producers and having a ~2% share of global production. The 14 largest stone producers represent 85.2% of the global pro­ duction and, consequently, are the locations that face major problems due to the inappropriate waste management of these materials (ABIR­ OCHAS, 2018a; Montani, 2019). The amount of waste generated during the processing of dimension stones has been estimated to be between 20% and 50% of the mined blocks. The volume depends on various parameters, such as the pro­ cessing type, size, type of cutting and polishing discs, and the type and size of the stones (Alyamaç and Aydin, 2015; Demirel and Alyamaç, 2018; Gencel et al., 2012; Karaşahin and Terzi, 2007; Rana et al., 2016; Saboya et al., 2007; Sarkar et al., 2006; Ulubeyli and Artir, 2015). If tailings from mining are considered, the total waste volume can reach around 70–80% (Hebhoub et al., 2011; Tozsin et al., 2014b). Dhana­ pandian and Gnanavel (2009) stated that 20–25 wt% of raw-stone blocks become waste at production. According to Torres et al. (2009), L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 Fig. 4. Flowchart of the stone-cutting process with honeycomb aluminium panels, adapted from Mineral System company (Mineral System, 2020). each ton of processed stone generates approximately 0.1 m3 of SW, with 0.08 m3/ton from the sawing operations and 0.02 m3/ton from the cutting and polishing operations. By considering that this waste usually contain 20-25 wt% humidity and present a density of 2700 (±100) kg/m3, it is estimated around 23 wt% dry SW generated from processing stones, with ~18 wt% from sawing and ~5 wt% from cutting and pol­ ishing steps. However, according to a report by Montani (2019), which exposes detailed information about the world production, consumption, tech­ nology, and profiles of leading countries of stones in the world, the processing waste generated represents 41% of raw-stone production. Table 6 lists data on the SW volume generated between 2003 and 2018 from the production of raw-stone and processing waste operations worldwide, obtained from Montani’s report. As listed, the volume of both raw stone and waste from both operations doubled in the same period. According to Dino et al. (2015), the costs related to sludge landfilling represent approximately 3% of the operating stone-working plant costs, and this suggests economic advantages, besides the obvious environ­ mental benefits, which can be obtained from proper waste recycling avenues.

Potential applications This Section presents the main proposed applications for SW recy­ cling from the most relevant literature studies. Additionally, by considering the previously collected SW data this study introduced innovative recycling proposals not yet evidenced in the literature. Although there are many possible applications for stone sawing waste, they can be summarised into three main general applications, namely, fillers for binders, ceramic formulations, and environmental applications. Table 7 summarizes these applications. There are also some specific applications related to the production of paper, paints, rubber, and other polymers which are exposed at the end of this Section. 7.1. Mortars and concretes Several studies have investigated SW incorporation into mortars and concrete formulations as a full or partial replacement for cement or fine aggregates. Some also used marble pieces as coarse aggregates. As the annual global concrete consumption reached approximately 25 billion tons (Tiwari et al., 2016) and aggregates account for 60–75% of the volume of traditional concretes, this could theoretically enable the reuse Fig. 5.

Omar et al. (2012) reported improvements of 30% in the compres­ sive strength of concrete cured for 3 days, and approximately 20% after 7 and 28 days using 5 to 15 wt% marble powder as an additive in the concrete. The authors did not provide the particle size of marble powder, but the measured specific surface area (11400 cm2/g) reveals its very high fineness, even higher than typical OPC’s, which usually range from 3000 to 6000 cm2/g. In this sense, the filler effect is probably associated with. Some authors reported improvements with higher contents of SW. Khyaliya et al. (2017) studied the workability of mortars by partially replacing sand with SW. The authors bring data of the particle size and water absorption of the marble powder with the river sand, allowing a more reliable comparison. The river sand and marble powder presented water absorption and fineness modulus of, respectively, 9.9% and 8.23%, and 2.13 and 1.45. They found that by incorporating marble waste from 25 to 50%, it was achieved improvements in mechanical performance due to the less water requirement. At 50% substitution, the water required to attain the required workability fell by 6% and compressive strength increased from 2.84 to 7.04 MPa. In this case, the main contribution of marble dust comes from the improvement of the workability instead of the filler effect, allowing for reducing the w/c ratio. However, this improvement in workability goes in the opposite direction to what most works reported. Şahan Arel et al. (2016) noticed a reduction in workability as the marble powder amount, in place of the fine aggregate, was increased. However, the loss of workability and, consequently, the higher water requirement due to the marble waste addition seems to be overcome with the usage of superplasticizers, also noted by Ergün et al. (2011). Gesoğlu et al. (2012) studied the effect of up to 20% of marble powder in place of the concrete binder. The water/cement ratio was kept at 0.35. The authors noticed that the higher content of marble powder, the higher contents of superplasticizer were required to keep the same slump flow. Tests carried out by Binici and Yilmaz (2007) and Hebhoub et al. (2011) also reported slump losses by replacing fine aggregates with marble powder. According to Rodrigues et al. (2015), superplasticizers are highly recommended. Without them, they noticed negative effects on the mechanical performance of concrete with up to 10% of marble waste in place of cement. The authors also found an increase in the compressive strength for concretes containing up to 5 wt% of waste as a partial replacement for cement. Other studies have also adopted this strategy (that is, superplasticizers) to preserve the workability of Table 6 Raw-stone production and waste generated in the world (2003–2018).

Concrete aggregates are divided into two distinct categories, namely, fine (predominantly smaller than 5 mm) and coarse (9.5–37.5 mm) (Kosmatka et al., 2002). Fine aggregates represent a quarter of the total concrete matrix volume (Tiwari et al., 2016), and natural river sand is considered the most suitable fine aggregate for concrete, but its exploitation might lead to serious environmental impacts, compelling authorities to implement restrictions (Bravard et al., 2013) and, conse­ quently, stimulating the usage of alternative materials. The same concern exists to find alternative materials to cement due to well-documented related environmental problems. Taking into account its high fineness, we focused on the usage of dimension stone waste in place of cement and fine aggregates. There is a consensus on the recycling viability of SW into cementbased matrices, however, many controversies regarding the optimal content, the influence on the workability of mortars and concretes, and the possible chemical interactions between the cement paste and the waste have arisen. The literature survey shows that the ideal SW content can vary to an extent, depending mainly on the characteristics of the waste, especially the particle size distribution, specific surface area, and chemical composition, and on the application designed for the concrete/ mortar. Many authors have shown that replacing Portland cement with up to 9 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 the cement content in the mix was reduced by 33%, reducing shrinkage and improving water and carbonation resistance. Rana et al. (2015) replaced the 10 wt% Portland cement with SW without compromising the mechanical properties of the concrete. The authors also reported that the higher the SW surface area, the lower the concrete workability. Mashaly et al. (2016) replaced up to 20 wt% of cement with marble sludge and observed an improvement in the mechanical properties of the obtained concrete without changing the hydration products. Vardhan et al. (2015) indicated that the replacement of up to 10% cement with marble powder did not compromise the characteristics of the mixture, and as opposed to the studies previously mentioned, the workability was increased. The authors did not explain the reasons for this increase in workability, but the SW used in the study by Vardhan (2015) had a specific surface area ~50% smaller than that used by Rana et al. (2015). The larger particle size of the waste might explain the improvement in workability. Singh et al. (2017b) demonstrated that 10–15% of cement can be effectively replaced by marble sludge. The authors noticed an increase in chloride permeability resistance with up to 15% replacement, but the resistance to carbonation decreased with an increasing waste addition. They attributed the improvement of chloride permeability resistance to pore refinement, and the reduced carbonation resistance to the lower bicarbonate alkalinity of the waste (89 mg/L) as compared to that of cement (113 mg/L). The mechanical properties were maintained for waste incorporation of less than 15%. Some authors have specifically studied the stability of the hydration products, especially in the long term and in adverse conditions (high temperature, marine environment, and under the effect of bad weather). Sudarshan and Vyas (2019) employed marble mining waste as a coarse aggregate in concretes exposed to high temperatures (between 200 and 800 ◦ C). The properties were like those of the control mixtures up to 400 ◦ C, whereas above this temperature, the concrete undergoes dete­ rioration. The results obtained are not out of common sense since it is known that marble-based or calcareous aggregates undergo decarbon­ ization in the 400 to 800 ◦ C range, resulting in higher porosities. However, the authors stopped the heating process right after achieving the maximum temperature. Without a holding time at 800 ◦ C, it is not guaranteed that all CO2 was released. Kelestemur et al. (2014) investi­ gated the compressive strength of mortars with up to 50 wt% of marble dust in place of sand at high temperatures. They held samples for 1 h at the maximum temperature. From the authors’ data, it is possible to notice a significant increase in porosity, but the authors claim that marble dust improved the compressive strength. This improvement is not well evidenced since glass fibres were randomly used together. Khodabakhshian et al. (2018) evaluated the properties and dura­ bility of sixteen concrete mixtures containing powdered marble waste as a partial replacement for mortars, replacing cement and fine aggregates. It was found that substitutions of up to 5 wt% improved the mechanical properties of the concrete obtained and with 10 wt% of marble powder, the properties were like control. Due to the high fineness of marble waste, higher than the fineness of fine aggregates used, the filler effect is probably present. The authors also raise that the CaCO3 from marble sludge can react with the cement paste to form calcium carboalumi­ nates. They support that calcium carboaluminates hydrates in the interfacial transition zone and changes the surface of the aggregate, turning it rougher and improving the bonding strength of paste-aggregate. Lastly, it is mentioned that the rate of hydration of alite is accelerated in the presence of CaCO3, resulting in a shorten induction period. However, they did not investigate the microstructure of mortars to provide evidence to support these statements. Gencel et al. (2012) partially replaced the aggregates of cement-paving blocks with marble waste. The authors noted that, in proportion to the increase in the waste content, the mechanical strength decreased, while the durability by freeze-thaw and resistance to abrasive wear increased. In addition to technical properties, feasibility studies have shown that the cost of concrete dropped from 34 to 30 US$/m3 Table 7 Main potential applications for SW.

The feasibility of using this waste while still meeting the re­ quirements implemented by specific legislations has already been considered. Alyamaç et al. (2015) found an ideal proportion of 40 vol% of waste while still meeting the TS EN 197-1 standard (TSE, 2002). This standard specifies compliance criteria, including physical and chemical requirements for commercial cement. Aruntas et al. (2010) showed that samples containing up to 10 wt% of waste in cement mixtures resulted in compressive strengths exceeding 30 MPa at 7 days, also in agreement with the TS EN 197-1 standard (TSE, 2002). Li et al. (2018) replaced an equal volume of cement with waste (as a filler) without changing the proportions of the mixture. In contrast to the common route (that is, replacement of cement or aggregates by waste), the authors replaced the cementitious paste with SW. With this method, 10 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 (~10%), when using 40% of marble waste as an aggregate, that is, 0.1 US$/m3 for each % waste added. Other studies used marble waste to improve the properties of the fresh and hardened state of self-compacting concretes (SCC) (Alyamaç and Ince, 2009; Tennich et al., 2015; Uygunoğlu et al., 2014). The use of SCC in construction is widespread because it combines high perfor­ mance and launching ease without the need for vibration and other additional processes. The preparation of this type of concrete requires the use of very fine aggregates and additives, which influence the con­ crete fresh state performance and are usually expensive. Accordingly, SW is potentially useful because of its high fineness and particles smaller than 200 μm (see Table 4). These characteristics are effective for the cohesion of mortar and concrete, without loss of energy during work­ ability, as is usual in other ultrafine mineral additions (such as silica fume) (Corinaldesi et al., 2010). Sadek et al. (2016) used three SW types (single or mixed marble and granite powder) in SCC. The results indicated that up to 50 wt% of the material could be used as a mineral additive. Corinaldesi et al. (2010) showed that a 10% replacement of commercial sand with marble pow­ der provided the maximum mechanical strength (~52 MPa) with the same workability in the fresh state. In the early stages, the authors also identified a positive filling effect on the samples. Durability studies for SCC have also been reported in the literature. Tennich et al. (2017) evaluated the incorporation of marbles, marble tiles, and gravel into different self-compacting concretes exposed to attack by sulphates, with the samples being immersed in seawater and a solution of sodium sulphate. The results showed that the SW incorpo­ ration had a positive effect on the durability of these concretes, as it increased the compaction and decreased the sulphate ion permeation that may be present in the air, water, and aggressive soils. Vardhan et al. (2019) evaluated the strength, permeation, and microstructure of concretes with marble waste partially replacing river sand as a fine aggregate. According to the authors, the maximum improvement was achieved at a 40% replacement level. The authors attributed the improvement in strength to the filler effect. The higher SW density as compared to the sand used probably also contributed to the improved mechanical properties. The higher fineness and the angular-shaped particles led to a concrete workability loss. Another point is whether the contribution of dimension stone pow­ der comes from the exclusive filler effect, or if there are also chemical interactions involved. Şahan Arel et al. (2016) reported an improvement in the mechanical properties and associated this phenomenon with the presence of CaCO3 and SiO2 but did not provide evidence. Omar et al. (2012) state the possible contribution from the filler effect and chemical interactions on mechanical performance. The authors state that active SiO2 from marble powder can react with Ca(OH)2 from cement to form secondary calcium silicate hydrate, making the structure more stable and denser. However, no evidence has been provided it. Since the au­ thors used low contents of waste with a relatively low content of SiO2 (14 wt%), this phenomenon seems improbable. The existence of a pozzolanic effect would be more plausible in granite-based stones due to the higher SiO2 contents in which can be directly noticed by quantifying the calcium hydroxide consumption by the Chapelle test. Indeed, Musil et al. (2021) did it and noticed that although granites contain large quantities of silicon (higher than 50 wt %), they are not very reactive, with a calcium hydroxide consumption under 400 mg Ca(OH)2 by a gram of sample. Vuk et al. (2001) evaluated the effect of 5% limestone addition on the compressive strength, setting time, and heat of hydration of clinkers. The authors observed a reduction in initial and final setting time with limestone addition. The compressive strength improved at 2 and 7 days but reduced with 28 days of hydration. The heat of hydration is not significantly altered within the first 3 days but decreases after 14 days. Some authors reported the formation of carboaluminate (Cochet and Sorrentino., 1993; Ramachandran, 1988; Sawicz and Heng, 1996; Tsi­ vilis et al., 1999) and carbosilicate hydrates (Chloup-Bondant; and Edvard., 1998; Péra et al., 1999) from the interactions of CaCO3 and C3A, and CaCO3 and silicate phases, respectively. It has been reported that the CaCO3 might accelerate the hydration of cement, especially C3S in the early stages, providing new nucleation sites for calcium silicate hydrates. CaCO3 can also react with C3A to form carboaluminates (Kakali et al., 2000; Ramachandra and Chun-Mei, 1986; Trezza and Lavat, 2001). According to Feldman et al. (1965), this reaction is driven by a solid-state mechanism, where the addition of CaCO3 modifies the initial reaction of C3A with water because of the barrier formation of hydrated calcium carboaluminates (C3A.CaCO3.xH2O) on the surface of C3A. Ramachandran and Zhang (1986) reported that the higher the amount and fineness of CaCO3, the higher the hydration rate of C3S. Husson et al. (1992) demonstrated the formation of calcium silicocar­ bonate hydrates for large quantities of CaCO3. Many works reported that the increase in resistance is related to the densification of cementitious matrices by the combined action of the filler effect and the possible formation of carboaluminates inside the pores, contributing to the reduction of residual porosity. Vardhan et al. (2019) stated that in addition to the filler effect, the densification of the mix was achieved by the improvement in the binding ability due to the presence of the calcium carboaluminate phase. However, this phase did not appear in their XRD analyses. Ramachandran (1988) showed the effect of CaCO3 on the C3S and C3A + gypsum systems. The authors evidenced that CaCO3 produces an acceleration effect and influences the early setting and early strength development. The formation of com­ plexes would be expected to influence the durability of cement. The rate of ettringite formation and its conversion to the monosulphoalumimate is accelerated by CaCO3. Even in the literature reporting that CaCO3 can react with calcium aluminate and calcium silicate phases to form hydrated products, there is no clear evidence that carboaluminate and carbosilicate hydrates are formed with marble waste incorporation. The particle size of waste and the crystallinity of those phase formed has to be considered. When the waste is used to replace fine aggregates, the average particle size must be compatible with the sand, which is large enough to be considered inert. In these cases, the physical filler effect is possibly the main reason behind the increase in resistance. When the waste fineness is comparable to those of cement, its replacement as a limestone filler is enabled, and secondary hydrated products, such as carboaluminates and carbosili­ cates, can (or not) be formed. This hypothesis still needs further inves­ tigation from a microstructural point of view. If, on the one hand, the formation of this compound was attributed to the increase in mechanical strength, the durability of concrete tends to be reduced, especially in the presence of chloride. Carboaluminate is unstable in a chloride envi­ ronment. The Cl ions from the environment react to form chlor­ oaluminates (Feldman et al., 1992) but Singh et al. (2017b) observed improvements in chloride resistance. Lastly, carboaluminates are also unstable in sulphated environments. Khyaliya et al. (2017) tested mortars containing 25 wt% SW replacing the river sand exposed to sodium sulphate and sulphuric acid solutions. The mixes were compared with a reference mortar, and it was concluded that SW can be safely used in both aggressive and non-aggressive environments. Most of the literature reveals that the positive effects of marble powder were more pronounced when used in place of natural sand than as a cement replacement. The main influencing factor is the grain size of the aggregates, with the filler effect explaining the gains in strength due to the high fineness of marble powder. On the other hand, the same effect led to a loss of workability, requiring the usage of plasticizers. The greater the surface area and lower particle size, the higher the loss of workability and water demanding (or superplasticizer). But even on keeping similar grading curves for marble waste and natural sand, the workability of concrete mixtures also decreased with increasing per­ centages of marble. This can be related to the chemical interactions of marble waste with cement or the uneven morphology of marble dust, with angular structure against the smooth and round natural sand 11 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 particles. SEM surface images of marble powder and river sand particles can be observed in (Awad and Abdellatif, 2019) and (Khyaliya et al., 2017), respectively. Concerning the chemical interactions between SW and hydrated cement, to the best of our knowledge, there is not enough evidence to support the chemical interaction of marble powder and hydrated cement. The probable phenomenon is the filler effect due to the high fineness of the waste. That is why many authors observed an improve­ ment in mechanical strength when used in place to natural sand with a higher average particle size, mostly up to 10–15%. When spaces are filled and the filler effect no longer exists, maximum improvement was achieved. So, the content of marble powder and the positive effects obtained will depend on the mix design of the control mixture. The better the mix proportioning of the original mixture, the less the contribution of the waste. Table 8 summarizes the approach and im­ provements from the literature analysed. Some authors have evaluated the use of SW materials as a component of eco-clinkers and the subsequent functionalisation of mortars. Raupp-Pereira et al. (2008) formulated new cementitious materials (clinkers) from industrial wastes, such as Al anodising mud, water treatment plant mud, marble sawing mud, and foundry sand. Belitic calcium sulphoaluminate cement was successfully obtained by El-Alfi et al. (2016) using 55 wt% marble sludge, 20 wt% gypsum, and 25 wt% kaolin at temperatures ranging from 1200 to 1250 ◦ C. These types of cement, usually used in precast and cold environments, are an alternative to conventional Portland cement, being more friable and can be obtained at lower temperatures. The use of marble waste as a filler in asphalt mixtures has also been evaluated (Akbulut and Gürer, 2007; Karaşahin and Terzi, 2007). In addition to the technical properties, the transport cost assessed in the study by Karaşahin and Terzi (2007) proved to be viable when compared to the cost involved with other commercial fillers. This is because samples using SW and limestone had similar plastic deformations, and the costs of transporting this waste were lower than the costs from commercial samples. Recently, Davidovits argued that the use of fly ash for the production of geopolymers would not be as sustainable as previously thought (Davidovits, 2020). According to this author, the generation of ash from the burning of coal generates large amounts of CO2, for example, 10 t of coal produces 1 t of fly ash and emits 33 t of CO2. Alternatively, the researcher encourages new studies on geological raw materials, that are available worldwide. Accordingly, some authors have used SW materials in geopolymerisation processes (Clausi et al., 2018; Tekin, 2016; Thakur et al., 2019). Palmero et al. (2017) used SW in geopolymers, composed of quartz, feldspar, biotite, and dolomite, with thermal curing at 80 ◦ C/48 h. Choi et al. (2010) studied the replacement of up to 30 wt% of the raw materials with SW in geopolymer formulations. The use of these materials tends to improve their mechanical strength. Simão et al. (2020b) studied different concentrations of stone sawing powder to replace metakaolin (0–90 wt%), generating products with different properties and possible applications. At 50 wt% SW, the compressive strength was satisfactory for application as a building ma­ terial (>25 MPa), while at 75 wt% the compressive strength was compatible with coating mortar (>6 MPa) achieving ~15 MPa. For comparison, previous studies achieved compressive strengths between 10 and 15 MPa using 75 wt% of biomass ash (De Rossi et al, 2019, 2020, 2019; Simão et al., 2020a). These results demonstrate that SW can be used as an alternative material to fly ash in geopolymer materials and provide great opportunities for advances in the reaction mechanisms. 7.2. Ceramic formulations Many studies have examined and characterised sludge derived from the sawing of granite, quartzite, and marble stones, envisioning their use in traditional ceramic formulations (Torres et al, 2004, 2007). Yesilay et al. (2017) obtained positive results when evaluating the possibility of using these materials (up to 27 wt%) in the production of artistic stoneware clay bodies sintered at 1160 ◦ C. Plasticity and shaping capability are particularly important for these products. According to the authors, and the addition of up to 27% of SW did not cause any deterioration in the dimensional stability of the product. However, the authors report a huge increase in water absorption (between 11 and 14%) in comparison to the standard sample (~7%). Although the au­ thors did not evaluate porosity, the increase in water absorption sug­ gested that this occurred very probably due to the release of CO2 from marble waste.

Simão et al. Journal of Cleaner Production 319 (2021) 128678 In addition to the use in white ceramic formulations, some authors have studied the use of these materials in red ceramic formulations (Menezes et al., 2005; Monteiro et al., 2004). Menezes et al. (2005) evaluated the possibility of using granite cut waste as an alternative raw material to produce bricks and tiles. The authors reported a gradual loss of plasticity with increasing additions of SW, but not enough to exceed the required values defined for extrusion. The results also showed that the waste has a chemical composition similar to commercial raw ma­ terials, which include clays, quartz, and feldspar. Samples with up to 50% of waste presented water absorption values below the maximum recommended values of 25% for bricks and 20% for tiles as well as a minimum module of rupture values of 5.5 MPa for bricks and 6.5 MPa for tiles. Even so, it can be evidenced a tendency of the higher the content of SW, the higher the porosity, especially in the case of bricks. In this case, this happens as SW is more refractory than the clay used. Segadães et al. (2005) used waste from sawing marble and granite in a mixture based on red clay to produce floors and tiles. The results show that the addition of ~30 wt% did not promote negative effects on the mechanical properties of the final product and has the additional benefit of enabling the use of lower temperatures during firing. The porosity induced by decarbonization of calcium carbonated was counteracted by the melted liquid formed especially due to the presence of alkaline and iron oxides, which act as fluxing agents. Saboya et al. (2007) used marble-derived waste into ceramic bricks fired in the 750 to 950 ◦ C range. The authors reported a loss of plasticity with the incorporation of waste, requiring higher contents of water for extrusion. They also noticed some improvements in the water absorption and strength with up to 20% waste. Acchar et al. (2006) used waste percentages composed of marble and granite between 10 and 50 wt% into fired the ceramic products sintered at temperatures ranging from 950 to 1150 ◦ C. The authors claim that granite and marble sludge can be added to the clay-based material with no detrimental effect on the properties of the sintered red-clay products. However, it can be noticed from their results a significant increase in water absorption and reduc­ tion in apparent density and flexural strength, except to the composition with the highest content of waste (50 wt%) at the highest temperature (1150 ◦ C), where the flexural strength is improved even with higher porosities. The authors attributed this phenomenon to the waste acting as a fluxing agent, strengthening the matrix. Vieira et al. (2004) studied the incorporation of granite waste (up to 40 wt%) in red ceramic formulations. The authors also found a reduction in plasticity with the increasing addition of SW. However, as the partner factory where the study was performed preferred to use excessively plastic formulations to soften the wear of equipment, the loss of plas­ ticity was not an issue for extrusion. Different from the previously cited works, the authors evidenced an increase in thermal shrinkage and bulk density with a gradual reduction in water absorption with up to 40 wt% of waste. Even so, the flexural strength was little altered by considering the standard deviation. Torres et al. (2004) studied a lot of formulations with granite-derived waste in place of feldspar in porcelain tiles, due to the similarity between waste and feldspar chemical compositions. According to them, depending on the dosage of waste and sintering temperature it is possible to obtain superior properties comparing to the commercial porcelains, with regards to water absorption, flexural strength. Torres et al. (2007) used granite and quartzite-based waste in red-clay-based stoneware tiles with high levels (60–70 wt%) of incor­ poration sintered between 1100 and 1200 ◦ C. The authors noticed values flexural strengths more than triplicate and water absorption decreased by more than one order of magnitude with the incorporation of granite sludge. Bilgin et al. (2012) added marble waste (up to 80 wt%) in the pro­ duction of industrial bricks sintered in the range of 900–1000 ◦ C. Ac­ cording to the authors, the addition of up to 10 wt% did not produce significant changes in the technical properties of the final product. However, their results show a clear tendency to increase water absorption and decrease flexural strength for most of the samples tested. Eliche-Quesada et al. (2012) produced bricks with marble waste (5–20 wt%) sintered at 950 and 1050 ◦ C. They claim to be possible to add up to 15 wt% of waste with no significant deterioration on me­ chanical properties when samples are fired at 1050 ◦ C. Lower temper­ atures increased the open porosity and, consequently, decreased the mechanical properties. Table 9 summarizes the analysed literature that used SW in ceramic products. Most of the raw materials used to produce the aforementioned ceramics, such as feldspars, kaolin, clays, and quartz are predominantly composed of silica and alumina, whose combination at high tempera­ tures generates mullite. Mullite is an aluminosilicate, which is stable at ambient conditions and exists over a composition interval ranging from 3:2 to 2:1 of the ratio Al2O3 to SiO2. Although the production of mullite from starting materials with particle sizes in micrometer-scale requires temperatures higher than ~1300 ◦ C (or from ~1100 ◦ C with nano-scale starting materials), metastable mullite can be formed at lower temper­ atures in multi-phase systems such as ceramic formulations due to the presence of other components. Granite and quartzite-based wastes are also predominantly composed of silica and alumina, allowing for to be added even at high concentrations without significantly changes the overall chemical and mineralogical composition of the targeted product. Most authors re­ ported improvements in the mechanical performance of ceramic prod­ ucts with this waste, with higher flexural and compressive strength and lower water absorption. The explanation for these achievements is the presence of fluxing agents on the chemical composition of waste, very especially the sum of iron, sodium, and potassium oxides, mostly in the Table 9 Compiled data from published works that used SW in ceramic products.

Simão et al. Journal of Cleaner Production 319 (2021) 128678 range of 7–18%. Therefore, the usage of granite-derived waste in place of starting materials with fewer contents of fluxing agents is the key to obtain ceramic products with improved properties. Torres et al. (2007) which obtained the best results with exceptional improvements con­ cerning strength and water absorption had the waste with the highest content of fluxing agents (~18% of iron, sodium, and potassium oxides summed). In summary, the presence of fluxing agents promotes the formation of phases with lower melting points. The melted liquid fills the pores and improves the bonding strength of the ceramic matrix, reducing the overall porosity and improving the mechanical performance. There are a lot of possible phases from the combinations of sodium, potassium, and iron oxides with silicoaluminate-based materials, as can be noticed through phase diagrams (Lecomte et al., 2004; Moosavi-Khoonsari and Jung, 2017; Roth, 1970; Yeşilay et al., 2017). However, different from the highly-controlled environment in which phase diagrams are built, in industrial processes, the chemical interaction between those oxides at high temperatures commonly results in a glassy phase, making their identification a challenging task. When marble-derived waste is added, especially at concentrations above 10 wt%, mullite is partially converted into anorthite (CaO. Al2O3.2SiO2). While mullite melts at around 1890 ◦ C, the melting point of anorthite is 1553 ◦ C (see Fig. 6). Therefore, even being calcium oxide highly thermally stable, its thermal interaction with silicoaluminatebased materials leads to the formation of anorthite, reducing the melting and sintering temperatures of ceramics. The formation of anorthite is helpful concerning the mechanical performance of ceramics. On the other hand, the formation of this phase does not seem to compensate for the open porosity generated from the decarbonization of marble waste. Still, anorthite just appeared in the mineralogy of prod­ ucts sintered at above 1000 ◦ C. Typical starting materials used in the production of clay-based ceramic commonly show variations in their chemical and mineralog­ ical compositions but still are broadly used. In this sense, even granitebased waste also presenting some fluctuations in their chemical com­ positions, their recycling can be viable by storing big lots of materials as done for other raw materials. In the case of marble-based waste, its incorporation in ceramic material aiming to increase the mechanical strength and reduce the specimens’ porosity might not be the best strategy. An interesting alternative can be its use as foaming agent to replace the commonly used calcium carbonate in the production of porous ceramics.Simão et al, 2013, 2015 Simão et al. (Simão et al, 2013, 2015) used CaCO3 (a commercial raw material) as a pore-forming agent in porous ceramics for filtration ap­ plications. The generation of pores was due to the decarbonization of CaCO3 at ~800 ◦ C, releasing CO2 and producing porosity. Some authors used commercial calcium carbonate (Zhu et al., 2016) or calcium carbonate-based waste (Souza et al., 2017; Teixeira et al., 2017) to produce glass foams for thermal insulation applications. Glass foams are materials with high porosity, generally above 60% by volume. They are widely used as structural materials due to their low density, low thermal conductivity, high sound absorption, high stiffness, and good chemical inertia. The ecological glass foams obtainment, using SW as a pore-forming agent, which presents interesting thermo-acoustic properties, seems to be a suitable destination for this waste containing high calcium carbonate contents. Porous anorthite-based insulating firebricks are another promising option. According to ASTM classification, which considers the bulk density and maximum service temperature, anorthite (CaO.Al2O3.2­ SiO2) is suitable for maximum temperature limits of around 1100–1200 ◦ C. Insulating firebricks must have a highly porous structure (usually between 45% and 90% porosity) and exhibit low thermal Fig. 6. Ternary phase diagram of the CaO–Al2O3–SiO2 system (Adapted from Yeşilay et al., 2017) with the highlight in the region of anorthite (CaO.Al2O3.2SiO2). 14 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 conductivity values. Some authors (Sutcu et al., 2012; Sutcu and Akkurt, 2009, 2010) successfully obtained anorthite-based refractories by using paper industry waste as a source of calcium carbonate. Analogously, these materials might be produced with SW instead. Finally, it is important to mention that, unlike recycling in cementitious materials, the use of SW in ceramic materials result in the release of CO2 during sintering process. Therefore, these applications do not fit perfectly into the concept of sustainability and circular economy, which aims not only to minimize the use of resource inputs and waste generation, but also carbon emissions (Geissdoerfer et al., 2017). This said, a life cycle analysis should be carried out in order to fully perceive the environ­ mental impacts of the proposed route compared to conventional foam­ ing agents. capacity of 1.20 mg/g in a neutral medium after 3 h of contact and was considered an effective adsorbent for fluoridated water (Mehta et al., 2016). Davini (2000) tested white marble SW from northern Tuscany “in nature” and calcined at 900 ◦ C as an SO2 sorbent material for atmo­ spheric emissions. After calcination, the desulphurisation properties of the waste were better than those obtained from commercial limestone. This improved performance is the result of combining a larger surface area with adequate distribution of the CaO pore size after heat treatment. When these environmental applications are suggested, one must consider the other ions that the waste may be solubilising at the time of application, as discussed in Section 4. These questions should be part of the study so that, in the end, there is no removal of an element toxic and the leaching of another. For these reasons, environmental applications are less explored, as compared to the numerous studies on traditional ceramics and cementitious materials. 7.3. Environmental applications The use of marble waste in environmental remediation applications, such as the removal of toxic elements from aqueous media (Ghazy et al., 2005; Mehta et al., 2016) and gaseous media (Davini, 2000), to the correction of acidic soils (Tozsin et al, 2014b, 2015, 2014b), has also been considered. Ercikdi et al. (2015) studied the use of marble granules as an additive to Portland cement applied to the cemented landfills of sulphide tailings. Although this material has not demonstrated a pozzolanic effect (reac­ tivity with calcium hydroxide), its use has improved the mechanical performance of the landfill in the short and long term, in addition to favouring the acid buffering capacity of the tailings (Ercikdi et al., 2015). The acid buffering capacity is the result of the alkaline character of the CaCO3 present in the waste, which can also be used for the remediation of acidic and calcium-deficient soils (Tozsin et al, 2014b, 2015, 2014b). Tozsin et al. (2014a) determined the effectiveness of using these materials to neutralise soil acidity. The results showed that the pH of the soil increased from 4.7 to 6.4 after using this material. In a similar study, the same authors (Tozsin et al., 2014b) employed stone and marble powder in hazelnut-producing fields, increasing the soil pH from 4.71 to 5.88, thus improving the production yield from 1120.3 kg/ha to 1605.5 kg/ha. The results suggest that marble waste can be successfully used to buffer acidic soils, thus reducing the negative environmental impacts (Tozsin et al., 2014a). Kabas et al. (2012) studied the possibility of recovering native vegetation in a deactivated tailing pond in south-eastern Spain using marble waste and pig farming mud. The results showed that these ma­ terials were effective in increasing the growth of vegetation, increasing plant cover and biodiversity, and reducing the mobility of heavy metals, such as Pb, Zn, and Cd (Kabas et al., 2012). Rapid industrialisation has led to an increase in the disposal of waste containing metals that are toxic to the environment. This, in turn, has created the need for alternative treatments to adapt the concentrations of these elements to the limits stipulated by environmental agencies (Ghazy et al., 2005). Accordingly, some studies applied SW to adsorb heavy metals (Ghazy et al., 2005; Mehta et al., 2016). Laboratory experiments were conducted in aqueous solutions to remove Al ions (Al3+) using marble powder as a sorbent material. The procedure was successful, and SW was not leached by acids because of the solubility of the sorbent. The control of this element is important because it is present in several compounds used worldwide for several applications, such as Al salts used as coagulants in water treatment plants (Ghazy et al., 2005). Similar to Al, other elements are controlled in drinking water worldwide. Fluoride is a chemical compound that can cause adverse effects when in high concentrations in the drinking water consumed by the population, leading to dental fluorosis and, in more severe cases, skeletal fluorosis. Accordingly, alternative techniques have been studied to solve problems with fluoridated water. Mehta et al. (2016) used marble powder after calcination at 650 ◦ C as an adsorbent for fluoride ions in aqueous solutions. The obtained powder showed an adsorption 7.4. Other applications By following the industrial applications of calcium carbonate, it is possible to identify other specific applications for marble-derived SW. For instance, calcium carbonate is widely used as an extender or filler in paints. The main purpose of an extender is cost reduction and also to increase spreadability and strength. They generally have weak colouring power. As marble-derived SW usually contains traces of chromophoric agents such as chromium and lead, its use can change the shade of the paints. Very recently, Tressmann et al. (2020) published the first research into the use of untreated marble waste (up to 80 wt%) as mineral filler in soil pigment-based paints and as an active pigment in waterborne paints. The authors observed through hiding power, abrasion resistance, microbiological attack, and resistance to weathering analyses that paints manufactured with marble waste meet the normative specifications for economical latex paint. The performance of the paints produced with soil pigments was improved by incorporating marble waste powder as mineral filler, especially for higher contents than 40%. The indicated formula with the highest total desirability was the paint with 30% polyvinyl acetate resin and 70% marble waste. Since marble-derived waste is an inert material for paints, other SW can be analogously tested. Lopes et al. (2019) studied the influence of the granite waste, actuating as mineral filler, on the performance of polyvinyl acetate latex paints produced with soil pigments. They found satisfactory results with a paint presenting 29% of PVA resin and 71% of granite waste. Although some studies report favourable results with the addition of SW in paints, the content and the influence of the SW chromophoric elements in the colour variations of the paints were not investigated. Indeed, the content of chromophoric elements in paints can broadly vary for different colours and manufacturers. Among the elements present in the SW, lead and chromium are widely detected in all colours, including white. Exemplifying, Megertu and Bayissa (2020) investigated commercially available oil-based house paints for residen­ tial use and found chromium contents ranging from 43 ppm (white) to 5450 (orange). Also, they found lead in all samples with different col­ ours from different manufacturers, with contents between 41 ppm and 51200 ppm. In this case, by considering that SW contains those elements at lower concentrations than found on commercial paints, the SW recycling as filler seems viable. The content of chromophoric agents can be later adjusted in the formulations. On the other hand, the presence of heavy metals, with or without SW, turns on the alert for another discussion, the health problems associated with human exposure to those paints (Sor­ oldoni et al., 2018; Turner et al., 2016; Wang et al., 2020). Differently, some authors carried out studies to obtain pure calcium carbonate from marble waste for use as a filler, enabling its use also in the paper industry, which is much more rigorous concerning the purity 15 L. Simão et al. Journal of Cleaner Production 319 (2021) 128678 of fillers (El-Sherbiny et al., 2015; Erdogan and Eken, 2017; Lu et al., 2018). Calcium carbonate, as well as carbon black, silica, clays, and others, are used as fillers of natural rubber compounds aiming for improving physical and mechanical properties. Ahmed et al. (2013) evaluated the potential of marble sludge as a filler in natural rubber. In this case, the efficiency of reinforcement into filled rubber compounds depends on a complex interaction of filler-related parameters and bonding quality between fillers and rubber matrix. The authors tested the rheological, mechanical, and swelling behaviour of composites. From their results, it can be noticed no improvements with marble waste incorporation in place to silica. Even so, they recommended its usage based on the cost reduction. Still concerning the usage SW into polymeric matrices, Awad and Abdellatif (2019) used dimension stone waste as reinforcement (10–50 wt%) in low-density polyethylene matrix and achieved improvements in mechanical and thermal properties. Abenojar et al. (2021) sought a composite material based on marble waste into a polyester matrix for being used as a floor or wall in buildings with improved fire resistance. According to the authors, marble improves the mechanical properties and fire resistance of polyester. The endothermic decomposition reac­ tion of CaCO3 releasing CO2 at around 700–800 ◦ C is responsible for the high fire resistance and the flame extinction. Similar findings with polyester-based composites with marble waste were reported by Nayak et al. (Nayak et al., 2020; Nayak and Satapathy, 2020). Lastly, pre-calcined dolomite and calcite are commonly used as solid base catalysts for steam reforming to H2 production (Constantinou et al., 2010), inspiring researchers to use SW instead (Kannapu et al., 2021). 2013). Analogously, recycling centres could be created near urban areas where SW could be managed and stored in large batches, aiming to homogenize their chemical composition. These recycling centres would reduce the disposal costs for companies, new jobs would be created, and would be easier inspected and regulated. Therefore, this strategy would bring environmental, economic, and social benefits to the region. Exemplifying the potential economic and environmental gains with SW recycling, Şahan Arel et al. (2016) estimated (from 2014 data on Turkey) a reduction of costs from US$40/m3 for concrete production to US$36/m3 when 50% of the fine aggregates is replaced by marble dust, representing 0.08 US$ for each % of waste added. Nevertheless, these values should be considered with caution as the potential cost-benefit will be hugely dependent on context, the mix design, and the type of concrete being produced. Uysal and Sumer (2011) reported a cost reduction of around US$ 4/m3 for each 10% of marble dust added into a self-consolidating concrete while preserving a mechanical performance similar to the control mix. 9. Final remarks This work conducted a systematic review on the cutting and pol­ ishing waste of dimension stones, including features such as classifica­ tion, potentiality, quantity, viability, and possible applications. Generally, SW is normally considered a inert meterial, as it contains elements that are already naturally found in natural stones. However, owing to the high fineness of SW (<200 μm) resulting from the cutting and polishing process, the possibility of some potentially hazardous compounds leaching must be considered. In this sense, the species’ leachability will ultimately dictate the real SW environmental impact. In addition, the leaching limits are different in some normative. As an example, the European leaching limits are more rigorous than those from the EPA-USA (Environmental Protection Agency of United States of America), with more elements being monitored. Concerning the possible applications for SW recycling covered in Section 7, its usage as starting materials in cement-based materials and ceramic formulations - as they are materials that traditionally encap­ sulate possible contaminants in their structure - seems the most prom­ ising destination up to now. In addition to the low particle size, it can be noticed a reasonable compositional and mineralogical regularity for different samples of marble-derived waste, but higher variability appears for other stones, such as granite-based waste. Even so, good predictability of the final composition can be expected, as the typology of the processed stones is well characterised. Also, the creation of recycling centres is another alternative to overcome this issue, ensuring the sustainability of the process. For beyond recycling possibilities reported in the literature for SW recycling, this work also brought new insights about possible applica­ tions and ways of dealing with SW aiming to inspire companies and local governments to put into practice such solutions, as well as future re­ searchers to try the new proposed applications described at this work or find other management ways and feasible recycling applications. 8. Challenges for SW recycling and economical and environmental aspects As with any mineral extraction activity, there will always be mate­ rials with little or no commercial interest and waste from processing. The best solution will always be the recovery and reuse of this waste material. To reduce waste generation through the circular economy in the dimension stone industry, some criteria can be adopted, including the carrying of better geological and geotechnical studies in the region; the adoption of improved quarrying technologies; and improve infra­ structure, water, and power lines (Careddu, 2019). The works cited in this study reveal that there are countless possi­ bilities for recycling SW waste, but those applications must be developed considering the chemical and mineralogical compositions of each waste and the local needs of the regions where the waste is generated. Applications based on sintered ceramics and cementitious materials appear to be the most promising recycling possibilities. In addition to the properties achieved, these applications emphasise the inertisation of possible contaminants that may be present in the waste, as discussed in Section 4. These applications are feasible almost everywhere and are a market opportunity because they are commonly consumed materials. Environmental applications, despite the alkaline character of SW and the consequent positive results for the remediation of effluents and acidic soils, have become more challenging. This challenge is mainly explained by the possible contaminants, which, unlike the application in ceramic materials, can be leached and contaminate the environment where the waste is applied. Another important factor is to perform greater management of these materials seeking a specific application, quantifying the local genera­ tion, characterising the compositional and mineralogical variability, the costs of transportation, and the adequacy of this alternative raw mate­ rial. Few studies encompass all variables, and few studies have examined different batches or compositional seasonality. Therefore, the applica­ tion of the material becomes more challenging. The creation of recycling centres can also be an interesting alterna­ tive for recycling these materials. Indeed, this approach was put into practice in Orosei Marble district in Sardinia, Italy (Careddu et al., CRediT authorship contribution statement Lisandro Simão: Conceptualization, Methodology, Investigation, Writing – original draft.
