Food-Waste Collection and Anaerobic Digestion (Solution Type)

Global (widely applicable)

Highlight

Separates urban food waste and converts it into biogas and fertiliser instead of sending it to landfill.

Extended description

Separate collection of food and other organic waste allows it to be treated through anaerobic digestion, producing biogas for energy and digestate that can be used as fertiliser. Diverting organics from landfill avoids methane emissions and recovers both energy and nutrients. The approach is widely used by cities and can be integrated with composting and broader circular bioeconomy systems.
