Biogas wipptal employs unique technology for protecting bodies of water
Biogas plants process livestock wastes and liquid manure in a fermentation process to yield fertilizers; at the same time, they generate renewable energy. The over-fertilization of farmland can thus be avoided and precious groundwater protected. In contrast to other biogas companies, Biogas Wipptal purifies the water derived from the liquid manure by means of a unique reverse-osmosis system; the resultant water is so pure that it can be safely discharged into a nearby stream. The solids derived from the livestock wastes and liquid manure are fermented and used to produce certified organic fertilizer pellets and liquid fertilizer.
