The paper discusses the use of non-traditional types of organic waste in vermicomposting in greenhouses on the territory of the middle taiga forest zone of Western Siberia. Experimental studies were carried out in the laboratories of the scientific and educational center and the center for collective use of the Institute of Natural and Technical Sciences of Surgut State University in 20012020. The main objects of the study were brewers grains, waste from the production of the Kristal brewing company in Surgut and wastewater sludge from the treatment facilities of the Gorvodokanal in Surgut. Additionally, the composition of complex composts included sand, office waste paper, waste coffee, food waste, leaf and grass litter, bird droppings and the microbiological additive Tamir. The compost worms of the Eisenia foetida Prospector species were used as vermiculture. 10 juveniles were launched in the first series of experiments and 50 juvenile worms were launched in the second series. The resulting vermicomposting is more effective in quality than the original substrates. The use of the hybrid Prospector can be effectively used in the disposal of non-traditional organic waste. Complex composts mature more efficiently when microbiological additives are added. In the studied substrates the content of heavy metals was reduced to MPC norms.
