With biodigesters we can provide environmental social and economical benefits for this farmer and for the eart


With biodigesters the farmers can put all manure inside it. Actually they use a manure pull before discard it in a river on in a soil without treatment. At this condition all methane produced in the pull goes to atmosphere. The gasholder of biodigester storage this gas for the farmer uses.
