Biogas & Biodigesters

Selected biogas and biodigester resources compiled by MIT D-Lab energy researchers.


2.4 billion people live without adequate sanitation, of which 70% live in rural areas, and 2.7 billion people rely on traditional use of polluting fuels for cooking, which causes problems such as air pollution and respiratory diseases. 

Biogas, which is produced through an anaerobic digestion process, is a feasible and affordable solution with which to tackle those problems. Additionally, this biofuel can help to reduce the incorrect disposal of the large and increasing volumes of biodegradable waste generated and its climate change effects.

Organizations and institutions

The following organizations have information about anaerobic digestion, biodigester technology, biogas technical and practical reports, business models, case studies, and other resources.

Biofertilizer as a byproduct of anaerobic digestion

During the biogas production process, biofertilizer is a byproduct of the anaerobic digestion. The fertilizer (slurry) from food waste is ready to use after the anaerobic digestion process. However, some guidelines should be considered in order to use urine and feces in crop production.
