The Waste Transformers

Energy and Water for Sustainable and Circular Food Systems

This project will demonstrate an innovative food waste-to-energy solution for powering water pumps and food processing in rural Uganda. The Waste Transformers’ small-scale, containerised anaerobic biodigester will convert agricultural and fish waste into clean energy at a local fishery. The biogas produced will power pumps to transport water from local sources to fish farming ponds and then pump the wastewater from the ponds to irrigation systems for smallholder farmers. The digester will also generate heat for fish processing and produce organic fertiliser to increase crop yield and long-term soil health. EEP Africa financing will enable testing and validation of the system and open the path for a commercial roll-out.

Outcome and Impact

The project will provide a circular solution to turn farm waste into productive energy that supports irrigation and food preservation. The system will generate 0.3 MW of energy and enhance access to water for over 500 crop and fish-pond farmers. By diverting food waste from landfills, the biodigester will reduce 635 tCO₂e emissions per year. The project has high potential for scale up in Uganda and other countries.
