Towards a Territorial and Political Ecology of “circular bioeconomy”: a 30-year review of metabolism studies

Abstract

In the context of the increasingly present policies of circular economy and the emergence of “Circular Bioeconomy” (CB), this article presents the results of a literature review on the sociometabolic research of biomasses. Six schools of thought are identified and distinguished according to their authors, their conceptions of metabolism, methodologies and social and spatial dimensions. Based on this state of the art, we propose an analytical framework that combines quantitative and qualitative approaches at the territorial scale, drawing upon the currents of Territorial Ecology and Political Ecology. This framework enhances our understanding and provides a critical perspective on the geography of CB. We compare discourses to actual practices by analysing biomass flows and power relations while adopting a critical perspective toward circular economy policies.
