Shared Dynamic Capabilities in Industrial Symbiosis Networks: how do physical and social exchanges increase joint competitiveness and adaptability? Jasper de Lange1, Alison Jenkins, Aglaia Fischer, Stefano Pascucci and Kris van Koppen Wageningen University Abstract In industrial symbiosis networks, firms are engaged in exchange of material and energy byproducts, with the aim of jointly achieving both economic and environmental gains. In order for industrial symbiosis networks to become successful, they must be adequately socially embedded; in other words, they must develop forms of social exchange: mutual trust, finegrained information transfer, joint problem solving and multiplexity. These characteristics allow the network to be more flexible, more adaptable and thus more competitive, because they enable the development of dynamic capabilities shared within the network. This is illustrated by describing and analyzing the case of INES Rotterdam. Keywords Dynamic capabilities approach, eco-industrial parks, industrial ecology, industrial symbiosis, social embeddedness 1. Introduction Resource based- and dynamic capability perspectives are often put forward, when discussing differences in firm performance and competitive advantage. The resources and dynamic capabilities of a company encompass the explicit and implicit strategic and tactical knowledge that distinguish the company from its competitors (Barney, 1991). There exists a comprehensive body of scientific literature on these perspectives, which has led to divergent results. What is clear though, is that scientists have always conceived of resources and dynamic capabilities as belonging to a single company i.e. being firm specific or on a firmlevel. In this paper however, we argue that dynamic capabilities can also emerge as a shared asset in a network of closely cooperating companies. In this paper we explore what role dynamic capabilities play in industrial symbiosis. Industrial symbiosis is a concept that originates from industrial ecology, a theoretical field that looks at industries as ecosystems with their own metabolisms of resources, outputs and wastes. When companies take part in industrial symbiosis networks they collectively strive for a competitive advantage, involving the physical exchange of resources, water, energy and byproducts (Chertow, 2007). This exchange of physical resources cannot take place without some sort of information exchange. During the process of building the network, building trust, 1 Corresponding author: jasper.delange@wur.nl sharing information and solving problems together, we believe that shared dynamic capabilities are developed. Therefore the following question will be answered in this paper. Can dynamic capabilities be developed and shared by several companies in an industrial symbiosis network? To find the answer we will apply the dynamic capabilities perspective on the case of INES, an eco-industrial park in the Rotterdam harbor (The Netherlands). In this eco-industrial park several companies have joined forces in an industrial symbiosis with the aim of making better use of resources and at the same time reducing waste and emissions. The next section elaborates on the concepts of dynamic capabilities, industrial ecology and industrial symbiosis. In section three the INES case is described. In the discussion section the INES case is further analyzed and a comparison is made between the findings in the case and the concept of dynamic capabilities. In this section the research question will be answered. The last section comprises a short conclusion and recommendations for future research. 2. Theoretical framework 2.1 The dynamic capabilities approach The dynamic capabilities approach draws upon the resource based view (RBV, also referred to as resource based theory). The resource based view states that every organization needs its own firm specific capabilities and resources in order to create a sustainable competitive advantage (Penrose, 1959; Teece, 1984). Resources are defined as “all assets, capabilities, organizational processes, firm attributes, information, knowledge etcetera controlled by a firm that enable the firm to conceive of and implement strategies that improve its efficiency and effectiveness” (Daft, 1983 in Barney, 1991). In order to create and sustain this competitive advantage the resources need to be valuable, rare, inimitable and nonsubstitutable (also called VRIN- attributes) (Barney, 1991). In other words, this means that the strategic resources of a firm should be valuable for the firm, different from the resources of competitors, immobile across firms and impossible to substitute with other resources. This resource based perspective triggered other authors to further elaborate on resource based theory. Whereas the resource based perspective stresses an isolating mechanism that occurs because of the specific resources each firm preserves, changes in the environment are not taken into account. For this reason Teece et al. (1997) developed another component of resource based theory, called ‘dynamic capabilities’. In dynamic capability theory the dimension of changing environments is added. Dynamic capabilities relate to the company’s ability to create, integrate and reconfigure the combination of internal and external competences and resources that can address changing environments (Teece, Pisano, & Shuen, 1997). This way, dynamic capabilities can help a company by creating competitive advantage in increasingly demanding global markets. 2 Literature on dynamic capabilities has always emphasized the importance of protecting firm specific resources against competitors. As stated above, successful resources are VRIN, meaning that they are well embedded in the firm’s often tacit knowledge. In the case of industrial symbiosis, companies work together by sharing material and energy flows (Ehrenfeld & Gertler, 1997). However, not only these technical material flows are important in an industrial symbiosis network, but also intangible assets like information, trust, interaction and motivation. The next sections will elaborate on industrial symbiosis theory. It will become clear how industrial symbiosis theory indicates the existence of dynamic capabilities that are shared within entire industrial symbiosis networks. 2.2 Industrial ecology and industrial symbiosis The concept of ‘industrial symbiosis’ originates from the wider scientific field of industrial ecology. Using the analogy of the food web in natural ecosystems, industrial ecology views industry as an interactive system, studying the input and output flows of industrial processes and trying to find ways to close cycles of nutrients (raw materials, products and waste) and energy (Frosch, 1992). The idea is that following this and similar analogies with ecology will enable industry to create ‘win-win-win’ outcomes in terms of economy, environment and society. In recent years, industrial ecology has increasingly become a field of interest that encompasses many other concepts and approaches. At the level of the individual firm, it now includes eco-efficiency, design for environment, pollution prevention and green accounting. Life cycle management, industrial symbiosis and industrial sector initiatives are involved on an inter-firm level. On a regional level, it includes studies of industrial metabolism (material flow analysis), dematerialization and decarbonization (Gibbs & Deutz, 2007). Industrial symbiosis takes a central place in industrial ecology research, because it directly involves linking businesses in ‘nutrient exchanges’ to form industrial ecosystems. “Industrial symbiosis has been defined as engaging traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water and by-products. The keys to industrial symbiosis are collaboration and the synergistic possibilities offered by geographic proximity” (Chertow, 2007). According to Chertow, there are three primary ways to implement resource exchange in industrial symbiosis: by-product reuse (for example through the cascading use of energy), utility or infrastructure sharing (such as sharing waste treatment facilities), and joint provision of services (for example through a shared cantina). The concept of industrial symbiosis is closely linked to that of ‘eco-industrial parks’ (EIPs). An eco-industrial park is defined as “a community of manufacturing and service businesses seeking enhanced environmental and economic performance through collaboration in managing environmental and resource issues including energy, water, and materials. […] The community of businesses seeks a collective benefit that is greater than the sum of the individual benefits each company would realize if it optimized its individual performance” (Gibbs & Deutz, 2005). How these two concepts – industrial symbiosis and eco-industrial parks – relate exactly is still a matter of debate. It is unclear whether by-product exchange 3 should be seen as a defining feature of eco-industrial parks (Gibbs & Deutz, 2005), and this results in ambiguous and sometimes inconsistent use of both terms by different authors. Some authors see eco-industrial parks as one possible way of creating industrial symbiosis; in this case industrial symbiosis could also be reached in other ways, for instance by a product chain approach, where firms are not necessarily located in each others’ proximity (Chertow, 2007). Others see industrial symbiosis as one possible configuration of eco-industrial parks; here ‘eco-industrial park’ is interpreted more broadly as an industrial park where companies work together to achieve sustainability goals, not necessarily involving by-product exchange (Van Koppen & Mol, 2002). Solving this ambiguity is not within the scope of this article. However, it is important to note that, because of the strong interconnected (and sometimes directly interchangeable) nature of the two concepts, we consider many of the observations made in literature about eco-industrial parks to be relevant for our current investigation of industrial symbiosis. 2.3 The social embeddedness of industrial symbiosis There are two key ingredients for the success of industrial symbiosis (Gibbs & Deutz, 2005; Tudor, Adam, & Bates, 2007): firstly the exchange of material by-products and energy; secondly some form social exchange, in other words, inter-firm networking, trust and collaboration. In this section we will take a closer look at the latter ingredient: what role do social exchanges play in networks that are already engaged in physical exchanges? The importance of the social dimension of industrial symbiosis is very commonly acknowledged in literature. A certain level of trust and willingness to cooperate are seen as requirements for ‘industrial symbiosis proper’ (exchange of materials and energy) to take place (Ehrenfeld & Gertler, 1997; Gibbs, 2009; Gibbs & Deutz, 2005, 2007; Hewes & Lyons, 2008; Tudor et al., 2007). The importance of these factors is exemplified by many failed attempts to intentionally plan and design eco-industrial parks from scratch and through policy intervention (Chertow, 2007; Gibbs, 2003; Gibbs & Deutz, 2005, 2007). The reason many of these projects failed is that it is hard to find companies willing to co-locate and link their processes with other companies they do not yet know or trust. This is perceived as simply too great a risk to take. Trust is needed before interdependencies through by-products exchange can be set up, because certainty and continuity of supply are extremely important to industrial companies (Tudor et al., 2007). Also, trust is needed in exploring the possibilities for byproducts exchange, because companies need to share (possibly sensitive) information about their inputs and outputs (Ehrenfeld & Gertler, 1997). Although many authors stress the importance of these social mechanisms for industrial symbiosis, only a few attempts are known where the issue is actually analyzed in a social scientific way. The social aspects of industrial symbiosis are still very much ‘undertheorized’ (Doménech & Davies, 2011; Gibbs, 2003; Van Koppen & Mol, 2002). The most recent and comprehensive attempt to address this knowledge gap is an article by Doménech & Davies (2011), in which they try to explain the emergence and evolution of industrial symbiosis in pre-existing industrial networks, including the social mechanisms involved. 4 Central in Doménech & Davies’ analysis is the concept of ‘embeddedness’, which refers to “the mechanisms through which social structure, cognitive processes, institutional arrangements and cultural context determine the action of economic and social agents” (Doménech & Davies, 2011). They view successful industrial symbiosis networks as ‘embedded networks’, in which long-term, close and cooperative ties between firms play a crucial role. These embedded networks have four main characteristics: 1) trust, 2) finegrained information transfer, 3) joint problem-solving, and 4) multiplexity of personal relations. Table 1 gives an overview of these characteristics, together with the conditions in which they arise, as well as their resulting benefits. The build-up of these characteristics in the embedded industrial symbiosis network enables the emergence of new capabilities that are not specific for individual firms, but are shared by the network as a whole. In other words, these capabilities enable the participating companies to develop a collective competitive advantage (Baas & Boons, 2004). They “allow companies to be more flexible and adapt more quickly in environments characterized by complexity and continuous change” (Doménech & Davies, 2011). Here we see a strong parallel with the concept of dynamic capabilities that is worth exploring further. In this article, we will provisionally call these emergent features of embedded networks “shared dynamic capabilities”. Trust Fine-grained information transfer Joint problem solving Multiplexity Mechanisms/conditions Size of the network Past-history and shared experience Common goals and values General reciprocity Emotional contractual ties Frequent interaction Learning by doing and close interaction facilitates deep understanding of the organizations dynamics Generation of tacit knowledge Routines of negotiation and communication Development of a ‘common language’ Diversity of roles that a pair of network actors can represent Embedded ties are a combination of business relation, friendship and other social/cultural attachments Outcomes Reduces the risk associated with transactions, by preventing opportunistic behavior Reduces access barriers and learning costs Promotes willingness to collaborate Flexibility and rapid response and adaptability Reduces the risks and costs, and increases the effectiveness of coordination Rapid identification of problems, due to implicit feedback mechanisms Cooperative approach Multiplexity promotes trust and willingness to cooperate Minimizes opportunistic behavior It confers stability and flexibility to the connections Table 1. Main features of embedded ties and networks. (Adapted from Doménech & Davies, 2011.) 5 Doménech & Davies identify three phases of cooperation through which industrial symbiosis networks evolve, to become increasingly more embedded: 1) emergence, 2) probation, and 3) development and expansion. In the progression of these phases, the four characteristics that facilitate this embeddedness – and thus the build-up of shared dynamic capabilities – also become increasingly manifest. In the emergence phase, the first relations between actors are developed and some straightforward opportunities for collaboration are explored. Generally, these first steps do not require large structural changes in processes or technology, but they do form a basis for trust and further cooperation. What follows is the probation phase. After some time, actors get a general idea of the dynamics of the network and of the opportunities for exchanges. This will lead to more exploratory collaborative projects. Once there is enough trust to experiment, and more successful linkages are achieved, this in turn creates more trust: “it is the positive experience of interacting over time that achieves trust between [...] actors and leads to the potential for more complex embedded networks over time” (Hewes & Lyons, 2008). The probation phase takes time and can gradually result in more integrated, shared decisionmaking routines between actors. If the second phase is successful, what could potentially follow is a phase of development and expansion. “Continuous interaction and accumulation of experiences of cooperation allow the thriving of embedded ties, governed by trust, tacit knowledge and joint problem-solving, and generate routines of cooperation that significantly reduce the transaction costs associated with it” (Doménech & Davies, 2011). These phases can arise and progress spontaneously, but in many cases the process can also be initiated, encouraged and speeded up by a third party, such as governmental body or a business association. Such a policy actor can have an important role in strengthening network ties and deepening the embeddedness of the network (Chertow, 2007; Doménech & Davies, 2011; Ehrenfeld & Gertler, 1997; Gibbs, 2003). 2.4 Comparison to other theoretical approaches To illustrate the differences and similarities between the approach proposed in this paper and existing theoretical approaches, a brief comparison is made here. Concepts that bear resemblance to our approach include knowledge spillovers and coopetition. These concepts are introduced below, while table 2 gives an overview of the main differences. It should be made clear from the start that these approaches – although they are distinct – do not exclude each other; it may well be possible for the processes described by each to coexist in a given situation. Coopetition can be seen as a hybrid between competition and cooperation amongst firms, which results in a complex relationship with contradictory logics of interaction. Examples are strategic alliances between multinational firms, or multiunit organizations where different brands opting for the same market belong to a mother company (Bengtsson & Kock, 2000; Tsai, 2002). Due to the competitive element, the playing field to evolve relationships and develop trust amongst actors is limited, because competing companies take a cautious 6 standpoint. This is a clear difference with industrial symbiosis networks, which are generally characterized by the absence of competitive threat due to the different industries in which firms are operating. However, when firms in similar industries are part of a larger industrial symbiosis network, interactions between those firms could take the form of coopetition. A precondition of effective coopetition is either a clear internal separation of competition and coordination activities, or facilitation of cooperative aspect by an external actor such as a collective association (Bengtsson & Kock, 2000) – the latter being common within industrial symbiosis networks. Shared dynamic capabilities in industrial symbiosis networks Knowledge spillovers in industrials districts / clusters Coopetition Participants Firms in different industry sectors (with differing input and byproduct flows) Firms in the same industry sector Firms in the same industry sector, or parts within a multi-unit organization Scale of interaction District District / region Up to global Driving forces Driven by an unplanned accumulation of bilateral agreements between firms, that encourage further cooperation Shared competences arise as an unintentional sideeffect of co-location, which can then be supported deliberately by local institutions Driven by specific and purposefully determined common mission/goals Outcomes Emergence of routines of collaborative problem-solving and joint learning, characterized by trust and tacit knowledge transfer Accumulation of sector-specific knowledge as an intangible shared competence that is not accessible to outsider firms Accumulation and creation of resources for joint problemsolving on predetermined activities of interest with set boundaries Source of competitive advantage Increased flexibility and adaptability, in addition to increased resource base Increased resource base (knowledge) Increased resource base (knowledge) and/or improved market position Table 2. Comparison between shared dynamic capabilities in industrial symbiosis networks, knowledge spillovers in industrial districts/clusters and coopetition. 7 Knowledge spillovers refer to the existence or emergence of shared competences between firms in the same industry, located within the same industrial cluster or district. These shared competences consist of knowledge flows (both explicit and tacit) concerning products, processes, technologies, consumers and markets, that are accessible only to firms within a district (Camisón & Forés, 2011). They are intangible assets that are hard for outsider firms to imitate, appropriate or substitute, because they are “largely district-specific, idiosyncratic and based on tacit knowledge, […] unique institutions and multiple links between actors” (Camisón & Forés, 2011). Knowledge spillovers emerge as a result of multiple factors: local availability of highly qualified, specialized and experienced human capital; local mobility of labor; local spin-off companies; informal social links between local employees of intra-district firms; and the existence of a community with commonly agreed-upon standards of behavior, embedded in local traditions (Camisón & Forés, 2011). Commonalities with embedded industrial symbiosis networks are the existence of tacit knowledge transfer and multiplexity of relations, but other aspects crucial to the emergence of shared dynamic capabilities in these networks – trust and joint problem-solving – are not at all emphasized in the literature. 3. The case of INES Rotterdam The Rotterdam Harbor and Industrial Complex (HIC) is an area that takes up over 10.000 acres and has thousands of companies that concern themselves with petrochemicals, logistics and wholesale. According to research done by Erasmus University, it is of high strategic and economic importance for the Netherlands (Bosch, Hollen, Volberda, & Baaij, 2011). In the mid and late nineties, the concepts of industrial ecology and industrial symbiosis were introduced and several companies started to realize that their handling of energy and resources could be more sustainable, efficient and cost beneficial (Baas & Korevaar, 2010). On the one hand, the large scale of the HIC - economically and geographically - makes it difficult to transform to more sustainable use of energy and resources. Yet, at the same time, transforming such an area is of high importance precisely because of its scale and impact. We will evaluate how such a large area with many different companies and interests is trying to transform to a more sustainable way of doing business, and how shared dynamic capabilities emerge as a result of this. In this section, there is a short case description of the phased efforts to establish industrial ecology systems between companies within HIC. In the subsequent discussion section, the case will be analyzed using the features and phases of embedded networks proposed by Doménech and Davies (2011). Finally, a closer look is taken into the aspects that stimulate the features of embeddedness and therefore help to realize it. 3.1 Case description The HIC area consists of many different companies. Most are members of an industrial association called Deltalinqs (Deltalinqs, 2011) that represents their joint interests. Deltalinqs initiated a project in 1994 called INES, an industrial ecosystem, in the Rotterdam Harbor and Industrial Complex (HIC), The Netherlands. It was meant to give attention to environmental issues. Deltalinqs sought advice on creating such a system and established contact with the Erasmus University and the University of Delft. The concept of industrial ecology was to be 8 adopted, because this concept had already been proven successful in the real life example of Kalundborg, Denmark (Kalundborg, 2011). Throughout the years several initiatives where implemented in INES, each new initiative building upon the experience of former ones. The different initiatives differed regarding their goals, emphasis, insights, and when they were implemented. The INES project can be clearly separated into three phases (Baas & Korevaar, 2010). Phase I: 1994-1997 A total of 69 member companies initially participated in the INES project and an appointed environmental coordinator represented each company. The most important statements and goals were formulated in the ‘INES Declaration’ (Baas & Huisingh, 2008; Baas & Korevaar, 2010). After feasibility studies were conducted by the partner universities, three projects (out of an initial fifteen), were selected because of their economic, environmental and collaborative potential. In this first phase no real innovations were made. It was mainly about assessing the current state and formulating and researching feasible ideas. Awareness was raised amongst the companies for the opportunity and need of efficiency improvements. Phase II: 1999-2002 (INES Mainport Rotterdam project) The findings and insights gathered in the first phase gave the incentive for a second program. In this phase waste heat utilization was identified as a considerable opportunity to explore and exploit within the area (Baas & Korevaar, 2010). In addition, some plans resulting from earlier feasibility studies were implemented. These new plans concerned water management, CO2 emissions, utility sharing and waste management. Deltalinqs broadened the scope by also including governmental stakeholders (local as well as national) and environmental organizations into the process (Baas, 2008; Baas & Huisingh, 2008). A strategic decision making platform was implemented to involve these different societal actors. Phase III: 2003-2010 (ROM-Rijnmond program) In the third phase, all industrial ecology programs were clustered in the ROM-Rijnmond program. This program focused on improving living conditions in the Rijnmond region and aimed at strengthening the HIC area. A new network platform was established to ensure participation of all relevant stakeholders, which stimulated the sustainability conscience of actors involved. In this most recent phase the collaboration between internal actors (other companies) and external actors (government and universities) is very strong, thanks to built up relations of trust (Baas & Korevaar, 2010). Besides strong relations of trust, knowledge established in earlier phases also contributed to the improvement if INES. By using this knowledge, reduction in CO2 was identified as a viable option for strengthening the HIC area. Because of its involvement in petrochemical processing which exudes CO2, the mission was formulated to become a leader in economically feasible reductions of CO2. Partly, this was initiated to ensure the transition 9 towards more sustainable and renewable options in the face of climate change and limited resources. Yet paradoxically, this mission is also important for maintaining a strategic and strong position of place in handling petrochemicals (Baas, 2008). 3.2 Case evaluation: features of embeddedness In this section, the presence of the first three features of embedded networks, trust, finegrained information transfer and joined problem solving (as formulated by Doménech and Davies, 2011), is evaluated for each development phase of the Rotterdam Harbor and Industry Complex . The fourth feature, multiplexity in personal relation, will be elaborated on in the case discussion. Phase I: 1994-1997 The formulation of the ‘INES Declaration’ exemplifies the objective of creating common goals and values to establish trust. Formulating and subsequently working towards realizing a common goal foster this feeling of trust. The cooperation also represents the start of ‘joint problem solving’ through developing a common language. Phase II: 1999-2002 (INES Mainport Rotterdam project) As stated above, the findings of the initial feasibility studies lead to the implementation of new plans. The joint compressed-air system that was fully operational by 2000 (Baas & Korevaar, 2010) is a good example of such a plan. Firstly, it is stressed that trust was needed for the company Hoek-Loos (supplier of compressed-air) to realize such a shared compressed air system. The trust ensured exchange of information between the companies as well as reduced investment costs. Next to trust, learning by doing is exemplified in this case. Through experimenting and eventually implementing this system, Hoek-Loos was able to design a utility infrastructure for compressed air and nitrogen. This system was also implemented within other companies in The Netherlands (Baas & Korevaar, 2010). Another interesting aspect is the formation of a strategic decision making platform initiated by Deltalinqs. As we have seen in the case description, the platform ensures the involvement of many different actors that can formulate shared goals and values: An aspect that enhances trust. In addition, the platform creates an opportunity for frequent interaction amongst the different actors (Baas & Huisingh, 2008). This in turn fosters continuous negotiation and communication that will ensure joint problem solving. Phase III: 2003-2010 (ROM-Rijnmond program) A striking element within the third phase is the formation of another network platform, this time with internal and external actors. Identical arguments can be made about how this network platform fosters the elements of trust as well as joint problem solving. It is stressed in the case description that the collaboration has increased between the different actors within the network platform, because they could make use of earlier built up relations of trust. This exemplifies that the ties become more embedded, because there has 10 been a personal familiarity created amongst the actors. A final aspect that can be recognized, is the (re)use of established knowledge. Knowledge that is gained through learning by doing turns out to be valuable knowledge, which is used to further experiment. An interesting example of this is the Happy Shrimp Farm. Two entrepreneurs got excited about the possibilities of using waste heat and CO2 that was identified in earlier phases. They made use of this fine-grained information transfer and further experimented and implemented these ideas into a company that now produces fresh king size shrimps (Baas, 2008; Baas & Huisingh, 2008; Baas & Korevaar, 2010). 3.3 Case evaluation: phases of cooperation From the above we can conclude that the features of trust, fine-grained knowledge transfer and joint problem-solving can be found and accumulated in each phase of the INES project. We also want to examine in which phase of cooperation INES can be currently placed (Doménech & Davies, 2011). By identifying the phase of cooperation we can establish how far the INES project is in building cooperation. The face of cooperation also says something about the depth of the influence of the three conditions. When applying these phases of cooperation to the INES case, we can state that INES has passed a certain probation phase, because the members have realized the opportunities of potential exchanges. In addition, the industrial symbiosis has become more embedded in the mindset of the companies. They continue their cooperation and communication through platforms and they discover and implement new opportunities. The industrial symbiosis has been integrated in most of the decision-making routines. We classify INES in the start of the development and expansion phase, because new relationships are built and existing ones are deepened. First the stakeholders increasingly became involved (Doménech & Davies, 2011). In addition, during the ROM-Rijnmond program, the existing linkages of trust are used and deepened resulting in further developing and implementing the sustainability goals of this program (Baas, 2008). 3.4 Case discussion In the INES case is has become clear that the presence of the three above-mentioned features can be found within each phase. Also, these features seem to be strengthened and further accumulated throughout the different phases of the INES project. Reaching the phase of development and expansion in the ROM-Rijnmond program (in which the three features have been accumulated much more than in the first phases) strengthens the assumption that there is an accumulation of trust, joint problem solving and fine-grained information transfer during the different phases of cooperation. This means that the social embeddedness of these three features in INES is strengthened. Social embeddedness results in more flexibility and adaptive power towards changing environments (Doménech & Davies, 2011), in other words, a shared pool of dynamic capabilities in the network. It is observed that Deltalinqs is a key player within industrial symbiosis, that ensures the three features. This emphasizes the importance of such a coordinator in continuously 11 facilitating opportunities to build trust (Doménech & Davies, 2011). It is important that Deltalinqs facilitates the educational services and interaction amongst the actors that lead to the building of trust and the development of local investment schemes, because these elements create a certain ‘collective competitive good’ for the companies involved (Baas & Boons, 2004). At the same time, it ensures certain ‘social glue’ that gives companies the opportunity to tap into valuable assets of each other, such as information and resources. Both this collective competitive good and the possibility to tap into each other’s resources and information are signs of dynamic capabilities being shared among these companies. The collective competitive good stands for gradually (during the different phases) developing information and strategies that are made up of the knowledge of several companies. Because these companies get to know each other during the development of the industrial symbiosis system, they will grow to trust and understand each other better, exchange fine-grained information more effectively and get used to tackling problems together. They are not afraid to share their VRIN resources anymore because they feel committed to each other and to the competitiveness of the industrial symbiosis network as a whole. 4. Conclusion The framework proposed and illustrated in this paper may not fit well with the reigning paradigm in management theory, which assumes companies must create their own dynamic capabilities and protect them from being copied by other companies. However, this paper means to demonstrate that dynamic capabilities could be even more valuable on the group level of an industrial symbiosis network than on the level of the individual company. The possibility of creating and sharing this collective competitive good amongst the members of the industrial symbiosis network attracts new companies to the network, resulting in an even more versatile network. By creating shared dynamic capabilities these capabilities can never be copied by a single company, because the fundamental strength lies in the interplay of knowledge that has been built over an extended period of time and can be maximally applied because of the trust and experience these companies have within the network. It has become clear in this paper that the dynamic capabilities framework can also be used in a broader context than the single company. Comparing the dynamic capabilities approach with the INES case provided the evidence of the existence of (industrial symbiosis) network wide dynamic capabilities that are developed between companies, instead of within companies. Moreover this sharing of dynamic capabilities opposes the original goal of dynamic capabilities, namely creating a sustainable competitive advantage for the company in an environment of competition. Instead, shared dynamic capabilities offer a way of collaborating with other companies in order to create a collective competitive advantage. This shared competitive advantage can be seen as taking place on a higher level, namely the competition between networks of companies. A major recommendation that follows from these findings, is a need for business management theorists to study the development and theoretical implications of shared dynamic capabilities in embedded networks, industrial symbiosis networks offering a 12 particularly clear case in which this development can be observed. The field of business management could benefit a lot from new insights into the emergence and functioning of dynamic capabilities and the possibilities for creating collective competitive advantage in this fashion. In the long run, the field of industrial ecology could in turn use insights from such studies for improving the understanding and development of industrial symbiosis networks even further.
