Defining Circular Economy Principles for Biobased Products

Abstract

To support progress towards the transition to a circular economy, the ability to measure circularity is essential. The consideration of the role biobased products can play in this transition is however still largely lacking in the current development of circularity monitoring approaches. The first step in coming to a suitable monitoring framework for biobased products is to define circular economy principles. In this paper, specific characteristics of biobased products were considered in defining six circular economy principles for biobased products: (1). Reduce reliance on fossil resources, (2). Use resources efficiently, (3). Valorize waste and residues, (4). Regenerate, (5). Recirculate and (6). Extend the high-quality use of biomass. In order to evaluate the circularity performance of biobased products with respect to these principles, what needs to be measured was defined considering both intrinsic circularity and impact of this circularity. The intrinsic indicators provide a measure of success in implementation of these circularity principles, and the latter impacts of circularity, i.e., impact of closing the loops on accumulation of hazardous substances and impact of circularity on sustainability (environmental, economic and social). Yet, to unlock the potential of a sustainable circular bioeconomy, strong accompanying measures are required.
