Abstract

Production of biogas with anaerobic degradation from organic waste is one of the pledge alternative energetic solutions, especially from organic manure made from animal farming and other residuals of agricultural production. According to 2005 livestock manufacture data daily quantity of animal excrements in Croatia, based on LSU number, is 784 015.26 m3. The aim of this paper is to determine the possibility of production of biogas from the most common types of domestic animals in Croatia. Anaerobic fermentation period of 40 days in mesophilic conditions produced from 1 kg of beef, 31 litres of biogas slurry and from pig slurry 14.83 litres of biogas. From our study it follows that the Republic of Croatia (based on the number of UG) could produce 426,995,250.00 Nm3 biogas annually.
Exploitation of biogas can decrease import of the referred energents, especially electric energy.
