Biogas in Pilze-Nagy

The purpose of this project is to utilize the organic waste that arises during mushroom production (exhausted soil) in an environmentally friendly way. Befor the installation of the biogas plant, a research and developement program had been performed to develope the methodology for the utilization of such raw materials. In the facility, 3430 tonnes / year organic waste arises during the cultivation of mushrooms. Besides this, pig manure and cannery waste are fed into the anaerob fermenter. 1 050 000 Nm3/year biogas is produced. It is fed into the CHP plant that produces 1 750 MWh/year electricity and 6 850 GJ/year heat. The electricity is fed into the electricity network. Thanks to the biogas plant, 1 820 tonnes/ year CO2 mitigation can be reached. Significant part of the heat could be utilized for heating (and perhaps cooling) the mushroom producing tents and the buildings of the facility. For this purpose, only the some hundred meters long district heating pipeline should be installed that would connect the CHP plant and the boiler room. The expected payback of the heat utilization would be about three years. The possibility of the installation of district heating pipeline and reconstruction of heating system is currently under consideration and it will be supposedly realized in the near future. The utilization and sale of the produced energy highly increase the incomes and competitivenes of the company.
