The World Biogas Association (WBA) and C40 Cities have released a report, titled "Global Food Waste Management: An Implementation Guide For Cities," that aims to help policy makers in cities improve the management of food waste.

The report, which was presented to the mayor of Rotterdam on Wednesday, outlines for city leaders the sources and impact of food waste; how to prevent and collect food waste; an overview of treatment technologies; a detailed description of anaerobic digestion (AD) and its products; and policy recommendations, barriers and implementation of sustainable food waste management.

Policy recommendations include undertaking large-scale food waste awareness campaigns; requiring businesses to separately collect food waste' providing separate food waste collection containers to households; and requiring all food waste to be "used" or processed through animal feed, composting or AD.
