There are many recyclable waste materials, such as wool, wool, wool, wool, fly, wool, etc., which account for 10% of wool raw materials, but they can not be used in textile and nonwovens production. In the past, there are two ways to deal with these wastes. One is burning, not only producing waste gas containing sulphide, but also producing toxic gas when blended with chemical fibers.
Two, it is pported to the garbage dump, wasting capacity, occupying land and polluting the environment.
There is a woolen textile enterprise in St Petersburg. There are 100 tons of solid waste discharged into the refuse dump every year.

The most recent research topic is the use of waste wool in basidiomycetes culture.
Specifically studied is an industrial blended woolen fabric (containing wool 60%, containing polyamide or polyester 40%), which produces the components and characteristics of the waste wool produced in its various manufacturing processes. The wool, spinning, weaving, dyeing and finishing waste wool is placed in the culture medium to cultivate basidiomycetes, and some strains are selected in basidiomycetes to grow in the culture medium, which can effectively synthesize biological enzyme preparations, and the addition of waste wool can enhance the activity of these enzyme preparations.
