“…In this way, the ancient concept of soil restoration by returning food residues to the soil is updated with the use of food waste as input for the agri-food industry. To illustrate, food waste may be used as feed for livestock and fish [33,34], as human food [35], as well as for the production of fertilizers [36,37]. For the purposes of this study, a traditional technology, namely composting, and another that is radically innovative, namely insects as animal feed, were compared in order to investigate the contribution of the acceptance of novel technologies to consumers' perception of the circular economy.…”

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.

“…In accordance with other authors [4,26,27] who have implemented LCA studies related to FW management, a functional unit (FU) of 1 tonne of FW to be treated was selected in order to carry out the comparison between the investigated scenarios. Furthermore, the avoided production of different energy sources and materials was also included in the system boundaries.…”

Comparative LCA of Alternative Scenarios for Waste Treatment: The Case of Food Waste Production by the Mass-Retail Sector

Food waste is one of the most important issues taken into account by the European Union due to its negative environmental, economic and social impacts. The treatment of food waste through recycling processes represents a solution for food waste minimisation. Concerning, in particular, the retail sector, it is necessary to define strategies for retail-oriented sustainable food waste management. The aim of this study is to compare the potential environmental impacts related to five scenarios (landfill, incineration, composting, anaerobic digestion and bioconversion through insects) for the disposal/treatment of food waste produced by a mass retail company operating in Messina (Italy) through the application of the Life Cycle Assessment method, in order to find the best treatment solution. Results based on the treatment of a functional unit of 1 tonne of food waste show that the bioconversion scenario represents the most preferable solution considering all of the impact categories analysed through the CML 2 baseline 2000 method, except for Global Warming, for which higher environmental performances are connected to the anaerobic digestion scenario. The incineration and the bioconversion scenarios show the highest environmental benefits when the production of alternative energy sources and valuable materials is evaluated through the inclusion of the avoided productions in the analysis.

“…To such purpose, LCA can be applied with different aims, for example to (Mattila et al, 2012): assess the benefits of realising IE applications (e.g. Chiusano et al, 2015;San Martin et al, 2016;Simboli et al, 2015); assess existing IE applications to improve them (e.g. Contreras et al, 2009); communicate to third party the performance of IE systems (e.g.…”

a b s t r a c tFood loss is a major concern from both environmental and social point of view. Life Cycle Assessment (LCA) has been largely applied to quantify the environmental impact of food and to identify pros and cons of different options for optimisation of food systems management, including the recovery of potential waste occurring along the supply chain. However, within LCA case studies, there is still a general lack of proper accounting of food losses. A discrepancy both in food loss definition and in the approaches adopted to model the environmental burden of food loss has been observed. These aspects can lead to misleading and, sometimes, contrasting results, limiting the reliability of LCA as a decision support tool for assessing food production systems. This article aims, firstly, at providing a preliminary analysis on how the modelling of food loss has been conducted so far in LCA studies. Secondly, it suggests a definition for food loss to be adopted. Finally, the article investigates the consequence of using such definition and it proposes potential paths for the development of a common methodological framework to increase the robustness and comparability of the LCA studies. It discusses the strengths and weaknesses of the different approaches adopted to account for food loss along the food supply chain: primary production, transport and storage, food processing, distribution, consumption and end of life. It is also proposed to account separately between avoidable, possibly avoidable and unavoidable food loss by means of specific indicators. Finally, some recommendations for LCA practitioners are provided on how to deal with food loss in LCA studies focused on food products. The most relevant recommendations concern: i) the systematic accounting of food loss generated along the food supply chain; ii) the modelling of waste treatments according to the specific characteristics of food; iii) the sensitivity analysis on the modelling approaches adopted to model multi-functionality; and iv) the need of transparency in describing the modelling of food loss generation and management.
