Anaerobic digesters process backyard or farmyard organic waste into biogas and digestate fertilizer. Biogas stoves can reduce emissions when replacing biomass or kerosene for cooking.
Impact:
Small biogas reactors that can be installed in homes and communities to enable cooking with biogas instead of wood and charcoal stoves which have health and environmental consequences. It is projected that by 2050, small biogas digesters that digest animal and crop wastes can replace 57-87 million inefficient cookstoves in countries in Asia and Africa. The cumulative result: 4.6-9.7 gigatons of carbon dioxide emissions avoided at a net cost of $23-$49 billion. These stoves increase operating costs however by an additional $100-$209 billion over the lifetime of the reactors.
