METHOD OF PROCESSING BARK OF CONIFEROUS AND DECIDUOUS TREES

摘要

FIELD: wood processing industry.;SUBSTANCE: method of processing the bark of coniferous and deciduous trees includes grinding the bark of coniferous and deciduous trees to the average size of individual particles1-7 mm, further mixing within 5-7 minutes of the grinded bark with manure or droppings of farm animals, anaerobic digestion of the resulting mixture at a temperature of 30-50°C and its constant mixing for 5-7 days. During the operation of anaerobic digestion of the mixture, the evolved biogas is collected, and after the end, the remaining sludge used as biofertilizer is collected.;EFFECT: reduction of the processing time of the tree bark to produce biofertilizer and biogas.;1 cl
