Abstract

Each year 590-880 million tons of methane is released into the atmosphere by microbiological activity. Approximately 90% of the methane emitted derive from the biogenic resources. Big animal farms with huge number of animals have big methane production. That is not ecologically acceptable. By correct management of organic manure it is possible to decrease environment pollution, at the same time producing energy and making profit. In 1996 Croatia ratified the UN convention of climatic changes. According to that Croatia must reduce emission of greenhouse gases in the period from 2008 to 2012 by 5% in relation to the initial year. One of the ways is to reduce the use of fossil fuels and increase the use of energy from renewable sources. Great and unused potential for energy production is farm manure and agricultural biomass. The aim of the research was to evaluate the possibility of using cow liquid manure in biogas production, to determine the biogas volume, its energy amount and how much energy can be supplemented with biogas on farms.
