Global Food Waste Management: An Implementation Guide for Cities

Author: Worlds Biogas Association, C40

Globally, about one third of all food produced is lost or wasted along the management chain, contributing to greenhouse gas emissions and other environmental issues, wasting tremendous resources in the production processes, and making recyclable materials in the waste stream harder to recover. As the human population urbanises and grows, cities have an opportunity to build on experiences from around the world to reduce their food waste footprint, recover nutrients from food waste, reduce greenhouse gas emissions through renewable energy generation and improve their overall waste management systems. Global Food Waste Management – An Implementation Guide for Cities sets out: – the experiences of cities around the world in coming to terms with their food waste; – the best practices for preventing and reducing food waste; – an overview of collection systems to ensure clean food waste is brought to treatment; – food waste treatment alternatives, from windrow composting to anaerobic digestion; – the use of outputs from the various treatment processes and how to best valorise them; – the policies needed to ensure food waste is sustainably managed.
