Ecologically feasible ways of cereal wastes recycling are considered and their comparative analysis is carried out. The description of granulation methods for waste is especially investigated and the most effective technical solution for the studied elevator is proposed. Grain wastes of category III are not suitable for cattle and poultry feeding, therefore, they are stored in the territories adjacent to a grain processing enterprise for a certain time, and then they are taken to the landfill or burnt. The wastes include the wastes from the process of grain cleaning with the grain content of not more than 2% and with the presence of straw particles - buckwheat, oats, barley and suction husks, scouring black dust. The given waste type of elevator has properties that make it possible to use them as a secondary material resource. Their recycling acquires an important environmental, economic and energy-saving significance. In Western Europe, the use of solid fuels - granules and briquettes - has become widespread. The main types of plant-growing subcomplex wastes in agro-industrial complex, which are used for solid, liquid or gaseous biofuels production, are straw, cut and husk of cereals crops, peeling, corn shell, flax bonfire and other plant materials.
