Field Testing the Integration of Slurry Separation Technology & Refrigeration Units with Anaerobic Digestion Systems in Uganda

Description

The anaerobic digestion sector in East Africa has sustained consistent growth in recent years, transforming wastes to energy in the form of biogas. Although small scale digestion systems provide valuable biogas for cooking, system limitations have reduced installation potential and the associated environmental benefit. This GCFSI-funded effort (1) evaluated low-cost slurry separation technology to reduce system water demands and increase effluent application to agricultural lands, (2) evaluated a dual fuel stove design to increase biogas use, (3) evaluated the use of absorption chillers for refrigeration from biogas, (4) completed evaluations of air quality in kitchens when using biogas, (5) completed an assessment of slurry and separated solids as maize fertilizers, and (6) developed continuing educational strategies. The team field tested many of these innovations at existing biogas systems operated in and around Kampala, Uganda. Working directly with stakeholders allowed researchers to test the innovations and translate years of primary research into sustainable, scalable, commercial outcomes for the biogas sector in East Africa.
