The report investigates using vegetable side streams, treated using a thermophysical technique known as steam explosion, as food ingredients and tests their functionality in model food products.

The report provides a baseline understanding of the current management approaches identified in previous research undertaken by REFRESH with respect to the policy concept of a Waste Hierarchy. It categorises management approaches that have been identified for 20 selected food production residues.

This brochure describes the interim results of the REFRESH (Resource Efficient Food and dRink for the Entire Supply cHain) project through May 2018. REFRESH’s research into the behaviours, economics, and relationships that lead to food waste will inform future recommendations for efficient and versatile solutions to food waste at all levels of production.

An expert seminar examined the viability of feeding treated surplus food to pigs and chickens. It examined the hazards and risk factors, and the environmental benefits. The panel concluded the practice is viable provided certain safety measures are enforced involving a combination of heat treatment and acidification and a system to prevent cross-contamination.

The United Nations estimates that if farmers around the world fed their livestock on the food that we currently waste and on agricultural by-products, enough grain would be liberated to feed an extra three billion people. To help food businesses contribute to such a grand waste-free future, REFRESH has built a web app for businesses to clarify which surplus food is suitable, and what needs to be done to send the food to animal feed in a safe and legal way.

The REFRESH project has evaluated the top 20 EU food waste streams having significant environmental impact. Thirty-seven priority waste streams were further reviewed to identify the top streams for modeling and detailed research with regards to valorization. 

The REFRESH project has evaluated the key EU waste streams having significant environmental impact. Over 290 waste streams were identified, scored and reviewed to produce a list of priority waste streams for further study. The list includes brewers’ spent grains, oil press cake and meat & dairy side-streams such as slaughter by-products and whey, as well as apple pomace, orange peel and tomato pomace.
