Certain methodology has been developed to study the destruction of organogenic waste containing biopolymer lignocellulose complexes, the composition of which is determined by the functioning of the natural soil-biotic ecosystem. Soils determine the stability of natural ecosystems. Soil quality is assessed by its fertility (humus content), which is regulated by the constant supply of biopolymers, the subsequent destruction and accumulation of intermediate substances in the soil-biotic complex, which are adsorbed on the mineral component of the soil with the formation of organomineral colloids or mineralized to biogenic nutrients or gaseous substances. The humified product was obtained using effective microorganisms, which are contained in the biologically active preparation “Tamir”. The preparation contains a consortium of 86 beneficial soil microorganisms existing in symbiosis: lactic acid, nitrogen-fixing, photosynthetic, cellulose-destroying bacteria, unicellular microorganisms, microscopic fungi and cellulose-lignin waste: food waste, industrial (sawdust), agricultural (barley straw). The main stages of anaerobic bioconversion of cellulose-containing raw materials are: hydrolytic decomposition of biopolymers; growth of cells of effective microorganisms on hydrolysis products and the formation of humified soil. Waste bioconversion was carried out in mesophilic conditions (25–40 ºС) for three days. The main advantage of anaerobic enzymatic processing of cellulose-lignin waste from other utilization systems is the minimum energy consumption for the fermentation process and the production of additional energy in the form of biogas.
