FIELD: processing household wastes into useful materials and fertilizers. SUBSTANCE: method for processing household wastes includes drying at temperature of 75-105 C, removal of metal inclusions, and pressing into bales. Remaining mass of household wastes is crushed up to sizes of coarse sand, mixed with water and passed through sand traps. Then, components heavier than water are withdrawn from sand trap to form bricks and blocks in mixture with cement. Floating organic matter is passed through arched sieve, mixed with waste water sediments and pilled. Pile is saturated with air oxygen and prepared into- organic fertilizer. Water with dissolved organic matter is directed to settling tank and repeatedly used in sand traps, and sediments are mixed with initial material after passing the arched sieves and waste water sediments. EFFECT: higher efficiency of processing household wastes into fertilizers and useful materials. 2 cl, 1 dwg
