METHOD OF OBTAINING BIOGAS AND FERTILISER FROM ORGANIC WASTES Russian patent published in 2009 - IPC B09B1/00 B09B3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to methods of organic wastes utilisation, namely to method of their recycling into biogas and fertiliser. Method includes preparation of base from hydrolysing material, assembling gas-drainage construction from rigidly connected pipes combining functions of vertical and horizontal gas drainage; sorting and crushing of wastes, their inoculation with methanogenic microorganisms and moisturising; filling layer-by-layer by pouring from upper part of gas-drainage construction with sprinkling of layers with gas-and-water-proof material; biogas is removed via gas-drainage construction, filtrate being removed via hydrodrainage system, mounted into base. Recycled by anaerobic microorganisms biomass can be used as fertiliser. After installation discharge cycle of wastes recycling is repeated.

EFFECT: simplification of method of organic wastes recycling into biogas and fertiliser, ensuring reliability of biogas removal from biomass bulk and cyclicity of wastes recycling process.
