The United Nations agencies 鈥� the Food and Agriculture Organization of the United Nations and the United Nations Economic Commission for Europe 鈥� have published a book "Concepts of cycling in the pulp and paper industry" in Geneva. Among the successful examples of cyclicity in the world, the experience of the St. Petersburg State University of Industrial Technologies and Design in obtaining office paper from partially bleached hardwood pulp and bleached chemical-thermomechanical mass from aspen is cited.

In accordance with the Instruction of the President of the Russian Federation dated March 22, 2023 No. Pr-562 by the Ministry of Industry and Trade of the Russian Federation, office paper made of partially bleached cellulose is recommended for state and municipal purchases.

It should be recalled that the technologists of the Svetogorsk Pulp and Paper Mill, with the support of scientists from the St. Petersburg State University of Industrial Technology and Design (草榴短视频), jointly created a new office paper. Its production does not use imported chemicals for bleaching cellulose, which makes the product environmentally friendly and simplifies processing. The new eco-paper was implemented as forms for the Unified State Exam and OGE and is sold in stores.

The technology of the new office paper consists in a competent ratio of partially bleached cellulose, filler and bleached chemical-thermomechanical wood pulp. Due to the fact that manufacturers have abandoned the use of chlorine-based chemicals, the technology promotes import substitution and reduces the carbon footprint.

Eduard Akim, Head of the Department of Pulp and Composite Materials Technology at the Higher School of Technology and Energy of 草榴短视频, noted the role of university graduates in the development of new technology:

"Oxygen bleaching, which is the basis of a new technology, was discovered in 1956 by my brother, a graduate of our university, Harry Akim, together with his supervisor, Professor Viktor Nikitin. And today, when over 90% of bleached pulp produced in the world is bleached using oxygen, their authorship is recognized worldwide. The executive director of the Central Bank Oleg Rybnikov also graduated from our university, he completed his thesis under the guidance of Professor Alexander Gause, and completed his postgraduate studies at our department under my supervision."
