Universitat Politècnica de Catalunya, Barcelona, Spain 1 Introduction The global trade of products that occurs since some years ago is directly related with the chemical flows. For example, products produced in China are sold in the USA and then recycled in Vietnam. This flow of material involves a movement of chemicals at the same global scale since the differents products that are traded (plastic toys, textiles, electronic appliances, paper, etc.) incorporate different chemical additives. These chemicals are added to the products in order to give them certain desired properties: flame resistance, protection to UV light, conductivity, color, etc. Therefore, many potential hazardous compounds are traded as chemicals or incorporated as additives in products. Their potential release of harmful substances to the environment can pose a risk for the nature and for the human being on a worldwide scale. Being aware of the fact that humans and the environment are subject to the risk of chemical impacts on a day to day basis, management of chemicals including reduction of risks has led to the rise of several policy instruments taking diverse forms (EU Directives, international programmes and agreements) as well as to co-operations both at the global and European levels. In that context, the REACH [1] regulation must be highlighted as a representative and valuable example. This background of chemicals and additives in products produced and marketed globally, makes an international harmonised assessment and management essential. A new framework for hazard evaluation and risk assessment of existing and new chemicals has been established through the RISKCYCLE coordination action that plays an important role in order to ensure the implementation of the aforementioned new legislation and to aim at a global risk-based management system of chemicals. 2 Riskcycle Coordination Action Chemical testing, research on risks, impacts and management options is carried out throughout the globe but quite fractionated to certain areas and sectors and much too often with little linkages between the different scientific communities. The coordination action RISKCYCLE collects a number of high quality researchers from different scientific communities to form interdisciplinary working groups to cover the wide range of aspects: The fate and behaviour of chemicals and products, 185 Damià Barceló Antoni Ginebreda Dani Guillén Rosa-Maria Darbra RISKCYCLE project: a new approach for assessing the risk of chemicals in a circular economy The assessment of chemical dispersion and drain over the life cycle of different type products, The risk-based management for chemicals and products The alternative toxicity testing to minimise animal tests The circular economy of the traded products The overall objective of RISKCYCLE aims to establish a global network to explore the synergies of the research carried out within different programmes and countries of the EU, USA, Japan, China, India, Brazil, Vietnam etc. and to facilitate the communication with researchers, institutions and industries and make the information about the risks of hazardous chemicals and additives in products and the risk reduction measures for substances widely available. In order to accomplish such a broad objective, Riskcycle has established and a global network of European and international experts and stakeholders from different programmes to define together future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products of a circular economy in a global perspective making use of alternative strategies to animals test if possible and necessary. The RISKCYCLE initiative will influence policy issues at a global scale, not only in developing countries but also in developed ones and will create awareness and enhance state of the art on risk-based management of chemicals and products among stakeholders. 2.1 Specific Objectives The specific objectives of RISKCYCLE are: to exploit complementary elements needed with regard to the research objectives, methodologies and data of ongoing as well as recently completed EU and international projects to specify demands for tools for ecological design of consumer products, production, use and reuse of products and waste recycled to secondary material and products. Methods such as LCA, risk assessment and risk reduction strategies, environmental impact analysis, material flow analysis and economics related tools are considered to achieve socio-eco-efficient solutions to create a powerful platform enabling discussion among all stakeholders on usage, risks, chemical properties of consumer products, labelling and the fate of certain chemicals in products traded, used and recycled in a global scale, identify problems and solutions to contribute to the UN Globally Harmonized System (GHS) for chemical substances and mixtures to start with a conceptual development of a global strategy for a risk-based management of chemicals and additives in recycling and trade products 186 Damià Barceló Antoni Ginebreda Dani Guillén Rosa-Maria Darbra RISKCYCLE project: a new approach for assessing the risk of chemicals in a circular economy to identify alternative testing strategies and methods to avoid the enlargement and the outsource of animal tests to East and Southeast Asia to identify knowledge and research gaps for future research activities to consider the most effective way of ensuring continuing progress in this field involving EU and other partners at global scale including also international organisations. The RISKCYCLE network closely collaborates with related projects, EU and international bodies and authorities to communicate and agree on standards and to avoid duplication and redundant work. 3 Workpackage work In this section a brief description of the aim and work done until the moment will be presented for workpackage 3 and 5, since they are the workpackages leaded by the authors of this communication. 3.1 Work package 3 The aim of work package 3 (WP3) is to assemble and evaluate existing information about the additives fate and behaviour at a global scale. CSIC (Spanish Research Council) is the WP3 leader. Currently detailed studies about the flow of additives from the production to reuse, recycling and waste are researched and analysed for the following sectors selected by Riskcycle: textile, electronics, plastics, leather, paper and lubricants. This will provide the basis for flow diagrams. A database of chemical additives is also being developed by this WP. Its aim is to establish a global network of information that will be very helpful for assessing the risks of hazardous additives in products. Data sources, which are screened and carefully analysed, are mainly research projects analysing hazardous components in products, reports and studies from EU and other countries, with special emphasis on the participating countries Vietnam, China, Brazil and India and already existing databases. Project partners CSIC and UPC (Polytechcnic University of Catalonia) have already designed and developed the database structure, capable to handle different categories of information relative to chemical additives (such as physical, chemical and ecotoxicological properties, documents, graphs, figures, images, or links to other websites). At the moment, CSIC is working on the fulfillment of the database in collaboration with the rest of the partners. Once the development period for the database is finished, it will be accessible via the RISKCYCLE web page to the members of the consortium. 187 Damià Barceló Antoni Ginebreda Dani Guillén Rosa-Maria Darbra RISKCYCLE project: a new approach for assessing the risk of chemicals in a circular economy During the first part of the project, each WP devoted efforts to research information on different additives used in one sector. WP3 was responsible for the data-mining of the leather and paper sector. A search of information related to additives of the leather and paper sectors was done. Based on their physico-chemical and eco-toxicological properties, their environmental occurrence and their production and trade figures a selection of the most representative additives of these sector was done. The selected substances for the paper sector were: Bisphenol A, Dibutyl phthalate and Isothiazolinones. In the case of the leather sector the selected additives were: PCP (Pentachlorophenol) and TCMTB ((benzothiazol-2-ylthio)methyl thiocyanate). This work has been the basis for the redaction of two chapters in the first volume of the Riskcycle book: Global Risk-Based Management of Chemical Additives I: Production, Usage and Environmental Occurrence in The handbook of Environmental Chemistry. 3.2 Workpackage 5 The main objective of workpackage 5 (WP5) is the identification of different methodologies that can be used to assess the risk of chemicals in products concerning human health and the environment. The final aim is to select the best and most convenient ones and apply them to a set of selected case studies related to the sectors and countries participating in RISKCYCLE project. This WP is led by UPC. The first task that was done by WP5 was the aforementioned data-mining concerning the additives used in the textile sector. The work was done following the steps in table 1: Table 1: Data-mining for the textile sector Task 1 Collection of general information on textiles and additives used in this sector. Task 2 Pre-selection of the most representatives groups of additives used in this sector. Task 3 Selection of 2-3 substances/additives according to several criteria. Task 4 Presentation of risk scenarios for these substances. First of all, a thorough survey of literature (scientific papers, internet sites, databases, etc.) was performed to identify the diverse processes and products used in the textile sector. The additives used in this sector were divided according to their function (e.g. softeners, flame retardants, dyers). Their potential harmful action to the environment and human health was analysed and taking into consideration all the information gathered, a pre-selection of the most representative groups of additives was carried out (flame retardants, repellent finishers, antimicrobial finishers, easy-care and durable press finishers and dyestuffs). 188 Damià Barceló Antoni Ginebreda Dani Guillén Rosa-Maria Darbra RISKCYCLE project: a new approach for assessing the risk of chemicals in a circular economy According to a set of criteria established by the WP5 partners, three substances were selected: brominated compounds –HBCD- (flame retardant), perfluorocarbon compounds –PFOA and PFOS- (repellent finisher) and triclosan (antimicrobial finisher). For these substances, a deep study on their potential risk to the environment and human health was performed, obtaining general risk scenarios for each case. As in WP3, the results of this research have been the basis for a chapter production for the first volume of the Riskcycle book. The second task carried out in WP5 has been a document gathering the different risk assessment methodologies for environment and human impact. From this work, a selection of two of them has been done after discussion with the WP5 members in different meetings: USEtox and 2- FUN. From now on they will be used to assess the risk of selected chemical additives in specific case studies. For the moment, these case studies will be settled in China and India and they will be focused on electronic waste additives, mainly lead and brominated flame retardants. Once getting the first results, new scenarios will be defined including other of the selected additives. These assessments will allow the WP to do a critical evaluation of the methodologies and of data requirement availability, identifying therefore the research gaps related to the additives risk assessment. 4 Literature [1] REGULATION (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), establishing a European Chemicals Agency, amending Directive 1999/45/EC and repealing Council Regulation (EEC) No 793/93 and Commission Regulation (EC) No 1488/94 as well as Council Directive 76/769/EEC and Commission Directives 91/155/EEC, 93/67/EEC, 93/105/EC and 2000/21/EC 189 Damià Barceló Antoni Ginebreda Dani Guillén Rosa-Maria Darbra RISKCYCLE project: a new approach for assessing the risk of chemicals in a circular economy 190
