TOMSK, Jul 12 – RIA Tomsk. TSU entered the federal project "Infrastructure for waste management of I and II classes of hazard"; scientists will create a technology to obtain composite powders from waste, their second development will allow to separate valuable elements from recycling products and use them in production again, the university's press service said.

Earlier it was reported that it is planned to build a recycling complex for disposal of l and ll class of hazardous waste in Seversk with the project capacity up to 50 thousand tons per year. It will be built by Federal State Unitary Enterprise Federal Environmental Operator, a subsidiary of Rosatom.

As the press service specifies, the enterprise is to be completed in Seversk in 2024. The federal project on man-caused waste neutralization (it's part of the national project "Ecology") involves both scientific and educational and industrial organizations. TSU will be responsible for developing new effective methods of separating valuable components from secondary raw materials for further use.

"Two developments of Tomsk State University were included in the complex scientific and technological project "Infrastructure for waste management of I and II classes of hazard". TSU scientists will develop effective ways of using such raw materials for the production of new products, in particular composite powders," the press service reported.

It is specified, that the creation of the pilot device and technology of obtaining composite powders from the technogenic wastes will be the task of the first project. The second will be aimed at development of technology of extraction of valuable elements and their compositions from secondary products of waste recycling, on their basis it is planned to produce a line of products with higher added value.

"In the process of electrolytic production, for example, the waste remains with a lower content of chromium and nickel. Further on they cannot be used as solutions for nickel plating or chromium plating, but nobody has completely removed nickel and chromium from them. If chromium and nickel are returned in some satisfactory form, for example, in the form of salts or metal, they can be put back into electrolysis production again," explains Victor Sachkov, Head of the TSU Innovation and Technology Center and Laboratory of Chemical Technology.
