Theoretical contribution of industrial ecology to circular economy.

Circular Economy (CE) currently represents a viable option for countries, governments, academia and society to transform the linear and semi-circular materials and energy flows into circular flows and obtain better sustainable benefits. In this sense, Industrial Ecology (IE) with its tools can assist in the transition to CE. Therefore, the main goal of this paper is to present the theoretical contribution of IE to CE. The methodology used was based on bibliometric analysis in the international context. With regard to the bibliometric analyses, we have identified that the evolution of CE would not be possible without the existence of IE concepts and tools, especially with tools such as Industrial Symbiosis (IS) and Eco-Industrial Parks (EIPs). Furthermore, three levels of IE contribution to CE were identified, such as: conceptual, technical and policy aspects. Finally, new CE based researches from an IE perspective with bibliometric analysis and with co-citation networks are possible, including, solid waste management and policies. [ABSTRACT FROM AUTHOR]
