Abstract:The current linear system of production and consumption is unsustainable. In the food sector, despite the fact that valuable natural resources are intensively used to produce and distribute food products, little is done to upcycle residues generated along the supply chain. Circular economy strategies are crucial for restructuring the take-make-dispose model through the active participation of all actors of supply chains. However, little is known about consumers' willingness to participate in circular economy. A structured questionnaire was submitted to a representative sample of Italian households to assess the willingness of consumers to be actively involved in closed loops aiming at reducing food waste. Consumers are involved by returning their organic food waste to retailers in exchange for discounts on the purchase of animal products. The organic food waste returned enters in the production process of animal products. A choice experiment was designed to analyse alternative programs. Two scenarios were presented: one with a traditional technology (composting), and a second one with a radically innovative technology (insects as feed). Preferences and trade-offs, in monetary terms, among attributes were computed. Results depict a comprehensive portrait of the potential participation of consumers to closed loops inspired by the principles of circular economy.
Recommendations are given to academics and practitioners interested in the bio-based circular economy model approach for transforming agri-food supply chains.
Transitioning into a circular economy (CE) has been recently proposed as an agenda for reconciling global industrial systems with natural equilibria, but the current understanding of CE is ambiguous among scholars. Informed by recent growing CE literature, this study summarizes through three key propositions a set of indisputable insights emerging from the CE debate. In particular, the paper: remarks how CE takes stock of concepts of other schools of thought to drive policy interventions; depicts CE as a systemic transition of global industrial systems; and highlights the role of eco-effectiveness to upgrade business-centered approaches to sustainability. The proposed propositions are expected to contribute to reducing ambiguities in the CE debate and to convey coherence to future research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
