Abstract

Valorisation of agri-food waste is an essential aspect of creating sustainable circular food systems. The European Research Area Network Cofund Food Systems and Climate (FOSC) and the SUSFOOD2 ERA-Net Cofund supported eight projects focusing on the valorisation of waste generated during primary production or food processing. The projects identified barriers related to the technological, socio-economic, legislative, and institutional challenges of developing a circular food system, and concluded that overcoming these barriers and promoting a circular bioeconomy requires a comprehensive approach involving multiple stakeholders, including fostering supportive policies, and addressing regulatory concerns. The collective experience of the eight projects demonstrates that it is essential to rethink the limitations imposed by the term ‘waste’, and instead to consider all agri-food residues as side streams which have the potential to be valorised as resources for food and feed production if they can be proven as safe to return to the food chain.

在可持续的生物经济中，“废物”是一个合适的概念吗？

农业粮食垃圾的价值化是创建可持续循环粮食系统的一个重要方面。欧洲研究区域网络粮食系统和气候共同基金（FOSC）和SUSFOOD2 ERA-Net共同基金支持了八个项目，重点关注初级生产或食品加工过程中产生的废物的价值。这些项目确定了与发展循环食品系统相关的技术、社会经济、立法和制度挑战，并得出结论认为，克服这些障碍和促进循环生物经济需要涉及多个利益相关者的综合方法，包括制定支持性政策和解决监管问题。八个项目的共同经验表明，有必要重新考虑“废物”一词所施加的限制，而不是将所有农业食品残留物视为侧流，如果可以证明它们可以安全返回食物链，则它们有潜力作为食品和饲料生产的资源。
