Summary:

The article presents the legal constraints for limiting carbon dioxide emissions in Poland. It has been shown that, despite unstable and unfavorable financial policies, investing in the construction of local biogas plants and converting them into electricity is justified. The technological processes in such installations have been described. The article presents a flowchart of the technological process of processing manure, bovine manure and maize for biogas. It has been shown that a herd of about 1000 cows provides enough waste that this enables the bio-power plant of 500 kW. Tabular data lists data for such installations and for installations with twice the power. The basic criteria for selecting the number of generating sets, the type of mechanical drive (motor) for the generating set and the generator itself, are given, so that the power sources can work both on the grid and in the island system (isolated). It was indicated the possibility of comprehensive development of all heat generated in the biogas plant.
