The digester's capacity will be dimensioned to match the farm capacity which are 3000 pigs at each cycle. The idea is to cover the investment costs of the biogas digester and bottling system by EEP fund and the Digester will be invest by the project partner. In exchange of the owner's engagement to allow the project partner right to use the land for construction and operation of the bio-digester the farm owner will be paid for price of the raw biogas.
