The main aim of this project was to draw one’s attention to contemporary biogas’s installation. Moreover this diploma presents most often applied substrates exploited in biogas installations (mainly in agriculture) and also its technical properties. The great example of the selection of raw materials is biogas plant that is being build recently in the podkarpackie region that 1 MWe of power can be generated by this kind of biogas plant. The main aspects that can be found in this diploma are environmental benefits that are strictly connected with using the biogas plant. This diploma also contains the next stages of the biogas production and environmental conditions necessary to initiate the fermentation of biogas. Possibilities of using biogas as well as industrial waste that appeared in processing of fermentation which firstly must be purified or improved.

Production of both electricity and heat energy in Poland is based mainly on natural fossil fuels, that while burning - significantly pollute the atmosphere. An important element of the current national energy policy is to seek after alternatives, and thusmore environmentally friendly energy sources. An increasingly recognized source of energy becomes the biogas produced in the methane fermentation bacteria process. The subject of the work is to calculate ecological effect, that will arise in the environment in case of replacing energy produced from coal by the energy from renewable sources. Analyzed landfill biogas is gained on municipal landfill Barycz in Cracow. In 2010, 8638,629 MWh of energy was produced in this Cracow landfill. To produce such a potential, 4309394 m3 of gas had to be sucked off from the deposit, however to gain such energy from coal, 1196,486 tons of coal would have to be burned. By using a renewable energy source which landfill biogas is, one can reduce CO2 emissions by 100%, sulfur dioxide by 95%, carbon monoxide by 73% and completely eliminate emissions of dust.
