Promoting Industrial Symbiosis: Using the Concept of Proximity to Explore Social Network Development

Abstract

SummaryIndustrial symbiosis (IS) has been identified as a strategy for promoting industrial sustainability. IS has been defined as the development of close working agreements between industrial and other organizations that, through the innovative reuse, recycling, or sharing of resources, leads to resource efficiency. Key to IS are innovation and social network development. This article critically reviews IS literature and concludes that, to inform proactive strategies for promoting IS, the understanding of the social processes leading to resource innovation needs to be improved. Industrial ecologists generally believe that close geographical proximity and trust are essential to the development of IS. This article argues, however, that there is a need to learn more about the meaning of, need for, and specific role of geographical proximity and trust in IS and, additionally, that other potentially important social factors have remained underexplored. To move IS research forward, this article suggests to engage with research in economic geography on the concept of ‘proximity,’ which draws attention to the ways in which geographical, cognitive, institutional, social, and organizational distances between actors might affect innovation. Arguably, the analytically distinct, but flexible, dimensions of proximity can be useful to explore how and why IS develops. The resulting qualitative knowledge would form a basis for researching whether general patterns for IS development exist and, more important, could inform public and private strategies that indicate which actions could be taken, as well as when and in what way to promote resource synergies and sustainable industrial development.
