All known (mechanical, chemical, biological) methods of raw materials processing out of the alternative materials have essential drawbacks. They are: high prime cost and low quality of the raw material processing, and the extremely low percentage of its output. At application of the mechanical method - there is high explosiveness of the process. At the chemical and biological technologies there is added even poor controllability of the technological process. Furthermore, at the chemical method of cottonine realization harmful wastes in large quantities are formed as the by-products
