BIO-DIGESTER. SUPPLIES ENERGY TO FARMS.

The digestive system of a cow served as a model to researchers 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 principle of action of the digestive system of a cow served as a model to Camilo Pagés and Alexander Eaton 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 geomembrane where polyethylene components and bacteria generate gas that is used as fuel for stoves or heaters, and even in the form of electricity. In very simple terms, Alex Eaton explains that his technology is a huge bag of 15 meters long and two meters wide and two more in height, which can contain up to 40,000 liters of liquid capacity, and treat one ton waste per day. However, they have adapted it to specific needs and created smaller Bio-bags of two by two meters, working with 20 kilos of manure. "The system is modular and can interface, it also is deployable and adjustable. On average, the return on investment is contemplated in a year and a half, and if you consider that the material used for the Biobolsa lasts longer than 20 years, there is much room for profit," says the journalist with a graduate degree in environmental protection.
