This paper aimed at analysing the current state of methods of increasing methane generation during treatment of organic sewage sludge. The authors considered the theoretical principles of biogas production and the main directions of intensification of methane fermentation processes. A chemical study of sediments produced at sewage treatment plants in the city of Kharkiv, Ukraine, showed that the C/N ratio in the investigated excess activated sludge is 4-5, in the mixture of primary and secondary sediment -5-6, in sediment from sludge sites -6 -10, which is significantly less than the ratio of 20:1, which limits the negative impact of increased nitrogen content in organic substrate for methane fermentation. The directions for rising speed of the first phase of sediment fermentation and directions for increasing methane output during fermentation of a complex organic substrate have been determined. The promising technologies of adding organic substrates, richer in carbon compared to sewage sludge, have been noted. This solution will not only make it possible to improve productivity of fermenters, but at the same time resolve the issue of organic waste management.territories adjacent to treatment plants due to the occurrence of fires, emissions of greenhouse gases and toxic substances, contamination of groundwater with environmentally hazardous compounds. At the same time, according to its chemical composition, this sediment can potentially be used as a fertilizer, and is also a highly promising substrate to produce gas fuel.
