Sažetak
Energy, as a significant driving force of the economy and of all social activities, represents one of the crucial issues in Europe today. Technologies that are currently available are still insufficient and it is necessary to carry out extensive research into various possibilities of the use of waste materials for the energy generation that will not present environmental hazard. Slaughter house waste has become a part of our everyday life. It is generated mostly in slaughterhouses for ungulates and poultry and, because of the increasing consumption of meat ; its quantities have been constantly increasing during the last twenty years. Slaughter house waste is processed into meat-bone meal and grease for technical purposes by treatment in rendering plants. After the appearance of the bovine spongiform encephalopathy the use of proteins of animal origin in animal nutrition was banned. Alkaline hydrolysis, as an alternative method of the management of slaughter house waste, imposes itself as one of the solutions for the disposal of high-risk proteins, thus opening new possibilities regarding highly profitable and environmentally acceptable technologies. This paper represents research in the field of alkaline hydrolysis effectiveness as a method for processing slaughter house waste, the use of the method as the pre-treatment in bio gas production and the use of that material in fertilization, comparing production of meat bone meal and hydrolysates.
