This work describes one of the promising and innovative concepts for the use of biofuel from animal fats. Diesel biofuel made from cheap raw materials can compete with traditional fuels of petroleum origin, especially in terms of non-toxicity and environmental cleanliness. Raw materials for the production of methyl and ethyl esters of fatty acids can be vegetable oils, animal and bird fat, lard, yellow fat and by-products of fish farming. The main component of oils and fats are triglycerides, which make up about 90-98% of the total mass of raw materials. In real production conditions, periodic emissions of fatty waste are not excluded, which leads to the loss of fat-retaining raw materials, which worsens the environmental situation. Therefore, the task of the poultry processing industry is to obtain food products from high-quality raw materials, as well as third-party products in order to reduce production waste. The purpose of the work is to analyze the process of processing fat-containing waste of poultry processing enterprises into biofuel and to study its potential in providing sustainable and ecologically clean energy. The research used technical chicken fat (CHF), which was heated to 75-80°C and kept at this temperature for one hour with constant stirring to remove moisture, and then filtered to separate insoluble impurities.
