Understanding the phenomenon of food waste valorisation from the perspective of supply chain actors engaged in it

The repurposing of surplus food and food processing by-products is a key aspect of the shift towards a circular bioeconomy. In the Netherlands, food supply chain actors are already working towards making better use of agri-food surpluses to improve food security and resource efficiency. By analysing the experiences of these actors, this study aims to identify the current state of the sector and highlight barriers and enablers of successful food waste valorisation. Based on a phenomenological analysis of 16 in-depth unstructured interviews with participants from the Netherlands, we empirically demonstrate that supply chain actors involved in food waste valorisation consider local embedding, societal perception, and food safety to be important aspects of their work. They often grapple with legislative and logistical uncertainties and face various ethical dilemmas such as having to pay for products that were once considered waste. Building on these findings, we propose that experienced professionals with a penchant for sustainability can play the role of 'transition brokers' as the food system moves towards a circular way of operating. We also posit that private standards and voluntary agreements could be a way for the sector to better manage the various bottlenecks that are characteristic of food waste valorisation endeavours.
