Upcycled by-product use in agri-food systems from a consumer perspective: A review of what we know, and what is missing

摘要: Abstract A sustainable bio-economy requires that by-products and side-streams in agricultural food production are reinserted into the value cycle, a concept also called valorisation or upcycling. The constitutes an important sustainability-oriented innovation practice contributing to waste reduction efficient resource use. However, while literature focuses primarily on technical side, there is little research societal economic implications, consumer perspective of such creation. This paper addresses this lack through systematic review empirical waste-to-value drink from past ten years, provides suggestions for further directions. It concluded acceptance products among consumers determined by individual, context product-related factors. Environmental concern awareness communication about environmental benefits avoidance can improve choice. There need wider variety methods, theories contexts studying phenomenon. Stakeholders researchers should take broader topic order accelerate uptake circularity interrelation other industry domains.
