The biodigestion process consists in the digestion of manure from pig farms. This process produces methane gas, carbon dioxide and manure. The gas is used to generate electricity. Manure is an organic fertilizer rich in nitrogen (1.2 kg/m2), phosphorus (0.24 kg/m2) and potassium (0.85 kg / m2), which is added to the soil used for livestock farming. These values lead to savings in energy and fertilizer consumption.

Project Results

Treatment and use of 10,220m3/year in pig farm effluents.

Savings of USD 108,274 in the use of manure for fertilization. In addition, no fertilizers were purchased since manure is added in the appropriate proportions according to the requirements of the soil (720 kg nitrogen/Ha per year).

Non-monetary savings: Irrigation of 1,656 Ha with manure. Reduction of odors and volatile organic compounds.
