Biofrigas for the farmer
Your agriculture gets several things from biogas production based on a raw material that already exists: Biofuel in the form of liquid biogas; carbon dioxide that can be used in, for example, greenhouses or beer at local breweries and heat that can be used for local heating needs. In addition, the digestate is an excellent, high-quality biofertilizer. After separation of carbon dioxide and methane, the other nutrients remain. Phosphorus and potassium remain, the nitrogen is mineralized into ammonium which is more efficient for the crops to absorb. The liquid biofertilizer is easier to spread and smells much less than manure from cow dung. Feed residues, residual products and organic waste from nearby businesses can also be used for biogas production. This can be, for example, leftover fat from, for example, restaurants and the like.
