FIELD: process engineering.
SUBSTANCE: organic wastes are laid layer by layer and liquid biological additive is added. The mix is biologically heated and subjected to anaerobic fermentation. Formed biogas is collected and diverted. Effluent is used as said biological additive in amount of 3-8% of the total weight of organic wastes including mineral fertilisers, N:P:K in amount of 0.1:0.16:0.18%, respectively, and local microflora with the density of microorganisms of 260×108 KOE/ml.
EFFECT: higher efficiency of sites, lower costs of cultures cultivation, accelerated processing of wastes.
