Abstract

Utilisation of organic waste from agriculture is one of the most acute environmental problems that require immediate solution. This problem is relevant for the majority of farms and agricultural complexes, regardless of the number of animals. Violation of waste disposal rules can lead to contamination of soil and water bodies, as well as to negative consequences for human and animal health. This paper considers the method of anaerobic digestion of agricultural organic waste as an effective solution to this problem. Anaerobic digestion is a process in which organic matter decomposes without access to oxygen, resulting in the formation of biogas and high quality organic fertilisers. The processing of organic waste in a biogas plant contributes to sustainable agriculture. The aim of the research is to increase the energy efficiency of the organic waste utilisation process by developing the design and substantiating the main parameters of a low-volume biogas plant. Experimental studies were carried out according to the known methods on the newly developed biogas plant. The digestion temperature was maintained within the range of 50-55 °C. Experimental studies allowed to determine the rational design and technological parameters of the low-volume biogas plant.
