FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing biofuel from vegetable wastes, particularly to production of pellets from winemaking wastes. Method of producing pellets, involving grinding of vegetal raw materials, moistening, moulding, cooling and packaging, is characterized by that the vegetal raw materials used are wastes from the wine industry, namely grape stalks. At that, grinding of raw materials is carried out to particle size of 1.0-1.3 mm, moistening of crushed raw materials is carried out to moisture content of 10-12%, moulding is carried out by forcing of crushed raw material through a matrix at pressure of 100-110 MPa and temperature of 200-250 °C and subsequent cutting into cylindrical granules.
EFFECT: method described above extends the range of methods for producing pellets, reduces the environmental load and improves the consumer properties of the pellets.
