One of the main problems of the modern world is the search for and supply of renewable energy resources that could compete with oil and natural gas. In recent years, the world is entering the era of biotechnology, which uses renewable raw materials to produce energy and materials. One of the sources of alternative types of fuel is peat, which is the cheapest type of fuel for the population, raw material for nutritious soils and organic-mineral fertilizers. The purpose of the work is to create the latest technology for obtaining composite fuel and fertilizers. The article examines the study of drying kinetics on a convective drying stand with an automatic system for collecting experimental data and their processing. The optimal modes of drying the composite mixture based on the solid residue of peat after the extraction of the humic component with crushed corn residues have been determined. According to the methods, the kinetics of heat-moisture exchange during drying of the composite mixture was calculated and it was determined that the generalized drying curves of the composite mixture coincide with the obtained experimental curves. The technology for obtaining humic substances and biofuel from peat and nutritious corn residues has been developed. Biofuel obtained by the technology on the basis of solid residue after extraction of humic substances from peat and nutritious residues of corn meets the standards of quality fuel and is 12.3 MJ/kg.
