FIELD: waste disposal. SUBSTANCE: layer of organic filler (sawdust, straw) is poured onto a floor with net-covered channels. Then a layer of worm-inhabited substrate is laid which is every-day watered. From below, air is blown through organic filler, whereas leaked water is withdrawn. As processing continues, new substrate layers are added and watered. In the layer of organic filler, which may be mixed with agricultural wastes, composting process occurs at optimum temperature and, by the end of processing of substrate into biohumus, optimum temperature is established for filler to be processed into substrate used in the following cycle. Installation constitutes building 1 with drained floor containing fan to supply air through channels 4 in the floor into organic filler. In the latter, optimum conditions for composting are provided with no need of additional room and expenses on heating the building. EFFECT: enhanced efficiency of process and reduced power consumption. 5 cl, 2 dwg
