Purpose: Production of non-polluting cellulose intermediate products from straw of one-year plants intended for manufactur-ing of paper and cardboard articles, as well as for usage as a fiber-filling material in food-processing industry.
Area of application:
- pulp and paper industry
- mining industry
- food-processing industry etc.

Advantages: 
- usage of by-products (lignin) as fertilizing in agriculture
- material- and resource-saving due raw materials' usage from available and cheap waste of agricultural production
- usage of standard equipment for pulp and paper production, as well as additionally modified (curing equipment)
- self-contained scheme of water recirculation is envisioned
- organization of small-mass production in radius of 50 km is economic efficient
Implementation: There were made the sample production series of paper and cardboard on the basis of composition with yellow straw pulp on nitrate, mono-sulphite and soda ways on the joint-stock company "Paper plant "Spartak"
Forms of cooperation: Sale of the licenses, organization of joint manufacture
