Clean fuel switch: Exploring the multiple benefits of biogas

February 2020 – This working paper explores the benefits of enabling a community in Kenya to switch from cooking with traditional fuels to using biogas which is created through the natural process of anaerobic digestion of organic waste.

clean fuel switchIndoor air pollution from burning wood, charcoal and animal dung for household cooking and heating causes an estimated 2.2–4.2 million premature deaths annually. CISL and the project team worked closely with the Dunga Beach community in western Kenya to select 50 households to receive a biodigester to use in place of traditional fuels. In addition, two large biodigesters and a purpose-built kitchenette were installed for a local enterprise to sell biogas directly to local restaurants and fish fryers.

The research identified that households embraced biogas cooking with two thirds of participants noting that their health had improved. In addition, households saved around US$19 per month which would otherwise have been spent on traditional fuels. The research recommends that a credit model is assessed to help scale up future household biogas deployment.
