The Bio-digester is like a mechanical stomach. It is fed with organic material (cow manure, food and vegetable waste, etc.), which is broken down by microorganisms inside the oxygen free bag to produce methane gas to use for cooking.

Waste that is not fully decomposed is pushed out the other side of the bag and can be used as fertilizer in vegetable gardens. The Bio-digester is a truly sustainable concept, it turns organic waste product into energy and fertilizer, and is a green technology that can help Kenya become more environmentally friendly.
