Proposal of a Dual Circularity Concept for Sustainable Design

Abstract

Current CE approach, and its many definitions, does not explicitly consider the interconnectedness of the biological and technological cycle. This paper uses state-of-the-art to articulate nuances of the CE to encourage a more comprehensive understanding of the concept from a perspective of both cycles. The results address that acknowledged sustainably driven shifts of resources between cycles are neglected in most state-of-the-art. Therefore, the Dual Circularity (DC) definition is proposed and further evaluated by three examples.
