METHOD OF A MASS PROCESSING OF A BIOWASTE WITH PRODUCTION OF A GAS METHANE AND AGRICULTURAL FERTILIZERS Russian patent published in 2005 - IPC

FIELD: biogeotechnology; engineering bioenergetics; production of gaseous methane and agricultural fertilizers.

SUBSTANCE: the invention is pertaining to biogeotechnology, in particular, to engineering bioenergetics. The method allows to reduce a biowaste processing duration. The household, urban and agricultural garbage (biowastes) in the unsorted state is loaded into rack stacks by a layer of 50-70 cm, distributing solid impurities for obtaining porosity. Then the fermenting chamber is sealed. Each 1.5-2 hours automatically the waste mass is humidified, and at an initial stage of fermentation the temperature in the chamber is kept up to + 55°C by the heating system ensured with system of a preheating. In 8-10 days the fermentation process is ended, the gaseous methane is finally pumped out by the air engine into a gas holder and grading starts: 10 % of the gained fertilizer is left as a seeding agent for the next charge. The soft and solid plastic impurities are stored for their further use as a feed stock at production of the necessary household items: packaging materials, containers, hoses etc.

EFFECT: the invention allows to reduce a biowaste processing duration.
