Abstract
The lack of support for construction and operation of installation of biogas plants in Poland makes looking for cheap and efficient substrates. The most commonly used substrate is maize silage. This is related to the high biogas efficiency and the advanced technology of its extraction. The problem, however, is the cost of buying the silage by the biogas plants, which has grown considerably in recent years, due to its wide use. It finds food applications, is a rich nutrition source for animals but is also the most commonly used substrate in the production of renewable energy for production of bioethanol as well as in biogas fermentation. As a result, maize is a desirable substrate on the market. This paper indicates the possibility of using of post-slaughter waste in biogas plants. The methane fermentation of these waste materials allows them to be safely disposed of, so that these substrates can be obtained for a small fee or even for free. Slaughterhouse waste materials have also shown high biogas and methane efficiency and are therefore the substrates desired in the anaerobic biodegradation process. It should be noted, however, that these substrates require additional thermal treatment prior to application into the fermentation chamber, which reduces the potential income for the biogas plant..
