A quantitative evaluation is given for the unusable wastes formed at various stages in the manufacture of woven cloths for technical purposes, which contain wool and synthetic fibers (polyamide and polyester). Analyses of the components and elemental compositions are given for the wool-bearing wastes, and their hygroscopic and toxic features are characterized. It is shown that the Basidiomycetes Trametes maxima, Pholiota highlandensis, Trametes hirsuta, Trametes ochracea. can be grown in liquid nutrient media including the wastes from spinning and finishing processes. There is increased activity of the oxidative enzymes in the Basidiomycetes Trametes maxima, Trametes hirsuta, Pholiota highlandensis on culturing in the presence of wool-bearing wastes, so these are considered as promising objects for growing on these wastes. The oxidative enzymes formed on growing Basidiomycetes on media containing wool-bearing wastes may be of interest for practical use.
