This report, developed within the IEA Bioenergy Task 36 Material and Energy valorisation of waste in a Circular Economy framework, highlights the critical role food waste can play as a resource for material and energy valorisation. With approximately 1.05 billion tonnes of food wasted globally each year—about one-third of total food production—there are significant societal, economic, and environmental implications. Food waste management is essential, not only to prevent wastage of valuable resources like land, water, and energy, but also to curb harmful emissions like methane from landfills.
The report emphasizes the need for accurate quantification of food loss and waste (FLW) to develop effective reduction or valorisation strategies. Various waste management options, such as composting, anaerobic digestion (AD), and incineration, were assessed using Life Cycle Assessment (LCA). Avoiding waste at the source showed the best environmental outcomes, while AD had the lowest impact for unavoidable food residues. The report further explores the potential of food waste as a feedstock for producing value-added chemicals and fuels, advocating for optimized valorisation processes to extract greater value while minimizing environmental harm.
