A chemical waste digester or biodigester is, in its simplest shape, a closed container, hermetic and waterproof (called reactor), in which the organic material is put for fermentation (animal and human excrement, vegetables waste- citrics are not included because they acidify, etc) in determined water dilution for them to, trough the anaerobic fermentation methane gas is made and organic fertilizers high in nitrogen, phosphorus and potassium, and also, the contaminant potential of the excrements decreases.

The biodigester uses a simple system to implement with economic materials and it’s been introduced in rural isolated comunities and countries Underdeveloped to obtain the double benefit of being able to solve the energy-environmental problem, also make an adequate management of both human and animal waste.

Oil Fox has the best technology for the development of many types and sizes of biodigesters to supply the different needs in relation with the waste we already have.

Magnitudes of production:

One (1) diary Ton of organic waste on average generates fifty (50) m3 of biogas per day. Also one cubic meter (1m3) of biogas generates one point forty five kilowatts/hour (1,45 kw/h)

In an average city type, each habitant generate one point one kilogram of waste (1,1kg) diary. Sixty (60%) percent of this is organic. This means (As to have a parameter), a city with one hundred thousand habitants (100.000 habitants) generates aprox. Sixty six thousand kg. (66.000 kg) of organic waste or sixrty six tons (66 TN).
According to the exposed data it can be produced three thousand three hundred cubic meters of biogas (3.300 m3) and so, four thousand seven hundred eighty five kilowatts/h (4.785 kwh or 4,78 Mw/h).
