poljoprivreda 16-1.indd POLJOPRIVREDA 16:2010 (1) 67-72 INTRODUCTION Exploitation of fossil fuels such as lignite, brown coal, crude oil and natural gas comes from the oxidation of carbon stored over millions of years in the Earth’s crust; the combustible energy when released in the atmosphere emits carbon dioxide (CO2). Increased concentration of CO2 in the atmosphere causes global warming, because it is a greenhouse gas. Fossil fuels are limited and concentrated in several geographic areas of our planet. The permanent status of the countries located outside of the oil-rich areas is uncertain and they are dependent on imported energy. Thus, the most European countries largely depend on imported fossil fuels from fossil fuel-rich regions such as Russia and Middle East countries. Due to limited fossil fuels in terms of availability and the ecology and the need for finding other sources of energy, the European Union has focused on the production of a number of alternative fuels: biogas, biodiesel, bioethanol and hydrogen. Of all the renewable energy, the fastest development is expected from biomass (Van Dam et al., 2007). Biomass is plant or animal origin material that can be used as fuel or for industrial production. It is a renewable energy source, and can be divided into the wood raw material, wood processing industry waste material, agriculture ISSN 1330-7142 UDK = 662.767.2:636.5 COMPARISON BETWEEN BIOGAS PRODUCTION FROM MANURE OF LAYING HENERS AND BROILERS S.

Rupčić (4), Daria Jovičić (2) Original scientific paper Izvorni znanstveni ~lanak SUMMARY Biogas plants that process raw materials from agriculture, such as poultry manure, are one of the most significant applications of anaerobic fermentation. In Asian countries, particularly in China, India, Nepal and Vietnam, there are several million very simple, small biogas plants that produce gas for household cooking and ligh- ting. In E
