FIELD: food industry.
SUBSTANCE: invention is related in particular to disposal of brewery waste. The method of production of a biodegradable moulded product with creation of water vapor pressure inside the composite mould includes the division of brewer's grains into two uneven parts, and the first smaller part is used without processing, with natural moisture content, the second larger part is subjected to a drying process until the moisture content is 0.1 to 20%, while the first part in an amount of from 1 to 10% of the measured volume is placed at the bottom of the mould heated to 140°C, then the second part of the material used is added there in the amount of the remaining volume, after which the upper part of the mould, heated to 140°C, is closed, and pressing is carried out for 3-7 seconds with a pressure of 1 to 100 t/cm2 with a simultaneous increase in the temperature of the mould in the range from 140 to 250°C, after which the mould is opened and the finished product is taken out.
EFFECT: invention makes it possible to dispose of brewery production waste (brewer's grains).
