The principle of action of the digestive system of a cow served as a model to create a container that receives organic waste, mostly livestock manure, where it is mixed with millions of bacteria to obtain natural gas integrated mostly of methane, called biogas, as well as a high-quality bio-fertilizer.
The biodigester, commercially called Biobolsa (bio-bag), transform the waste in a container made of high-density polyethylene (HDPE) geomembrane where the polyethylene components and bacteria generate gas that is used as fuel for stoves or heaters, and even in the form of electricity.
