Name:
Biogas plant in Skrzatusz

Location (settlement, country):
Poland, Skrzatusz 96, 64-930 Szydłowo

Brief description of the technology:
The agricultural biogas plant in Skrzatusz uses distillery slop, carrot marc and potato pulp as the main substrate for biogas production. Additionally, there is a possibility for the utilization of 10 t offal per day as well as to use bad quality grain. The biogas plant processes 80-90 tons of substrates per day 50-70% of which is slop from the nearby distillery. The first element of the infrastructure is the place for the provision of substrates consisting of two reservoirs for the initial liquid substrates and a dispenser for plant feedstock and wastes from food processing, there is a silo tank for grain and there is a reception station for animal origin wastes from slaughterhouse. Another element is a mixing tank with a capacity of 6 m³, which gets sufficient amount of substrates. From the mixing tank sufficient amount of mixed and ground substrate goes to the two fermenters with a capacity of respectively 1000 and 3000 m³, where the actual process of fermentation and biogas production takes place. In the tank with a capacity of 3000 m³ there is also a major gas storage facility. Biomethane after being desulphurized, dried and compressed goes to the engine working in cogeneration with a power of 525 kWe generating electricity and heat. For the biogas plant’s start-up purpose as well as in the event of engine failure a gas boiler was installed. Produced electricity is sold to the grid, while heat is used for the biogas plant’s own needs and the production needs of a nearby distillery. Production residues go to a covered lagoon, above which there is another gas storage, which is followed by further recovery of biogas during residue storage. The magazine also serves as security for the cogeneration system failure, because the pumping of a certain quantity of gas is possible. Fermentation residues are finally received by farmers, and they go to the fields as fertilizer.

Why is it a „Best practice”:
Agricultural biogas plant in Skrzatusz in the biogas production process uses post-production residues, so the substrate does not compete with food products, as is the case with the use of maize silage for energy purposes. An additional advantage is the cooperation with the nearby distillery, from which the biogas plant gets slop, and at the same time sells heat needed in the ethanol production process. The synergy brings mutual benefits for both the biogas plant and distillery. Biogas plant activities contribute to reduction in the consumption of fossil fuels and the emissions generated during their combustion, the reduction of greenhouse gases, nitrous oxide and methane. It also creates new opportunities for rural areas.
