This article discusses the global problem of the exhaustion of natural resources in the territory of the Russian Federation at the present rate of export and consumption, as well as environmental pollution products of combustion of fossil fuels. It is argued the idea of ​​replacing the traditional sources of biogas energy. The article is subject to consideration of the topic of recycling organic waste. Compares the volume of produced biogas, depending on the feedstock composition. Based on the work shown that the amount of biogas that can be isolated from various agricultural waste under anaerobic conditions of processing depends on the amount and composition of the substrate, the process conditions, the bacterial composition in the installation and other circumstances. It is found that the release of biogas starts on average 3-5 days. It depends primarily on the ratio of proteins, carbohydrates and fats contained in each individual constituting the substrate, as well as the "push start", which acts as the temperature of the process.

Based on aircraft monitoring data for the period 2017-2021, an analysis of methane concentration in the atmosphere over Central Yakutia at altitudes from 34 m to 3,000 m was carried out. Seasonal variations were identified that minimum methane concentration values are characteristic of the warm period, while maximum values are characteristic of the cold period. The vertical profile of methane concentration shows stable stratification. Maximum concentrations are recorded at levels of 34–100 m, and minimum concentrations are recorded at altitudes of 2000–3000 m, regardless of the time of year. It is shown that intense wildfires in 2021 disrupted this vertical structure.
