Scientists at MRSU, have developed a polymer composition that includes recycled polyethylene and TetraPak multilayer packaging waste (multilayer packaging of products made of cardboard, foil and polyethylene). The presented material will be useful to enterprises in the construction industry and furniture production and can be used to create floor and wall coverings, paving slabs, furniture facades and partitions. Compared with analogues, the development has improved elastic-strength characteristics — increased strength, tensile modulus of elasticity of products and a 2−3 times reduction in cost due to the reuse of waste. «To produce the material, low-density polyethylene is melted at a temperature of 150 °C. Then shredded TetraPak packaging waste with a particle size of less than 400 microns is introduced and mixed with polyethylene. The resulting mixture is unloaded into a tray and cooled to room temperature,» commented Anton Kuzmin, Ph.D., Associate Professor of the Department of Mechanization of Agricultural Products Processing at the Institute of Mechanics and Energy. Currently, to recycle multi-layer TetraPak packaging, researchers are using sophisticated technologies that separate it into aluminum, cardboard and polyethylene. The method of MRSU scientists is more accessible and simple and can significantly facilitate the process of exploitation of this type of waste. «The use of recycled materials is one of the steps towards reducing production costs, efficient consumption of resources and improving the environmental situation. For example, the invention of scientists from our university can be used for the production of products for engineering and technical purposes, which will create conditions for the conscious use of polyethylene and TetraPak packaging,»noted the Rector of MRSU University Mr. Dmitry Glushko. The work was carried out within the strategic project «New Generation Materials and Energy Saving» of the «Priority 2030» program.

Scientists fr om our university and Jiangsu University of Science and Technology (Zhenjiang, China) are preparing a joint project to create a hybrid power plant for unmanned systems based on hydrogen technology. The Scientists plan to develop a technology for creating an energy source for marine use based on fuel cells. In addition to many important projects, last year the two parties decided to create a joint institute wh ere students will be trained in 7 fields. Upon completion of the training, students will receive diplomas from two universities (a dual degree program). The first intake of students will take place in 2025. Scientific and educational cooperation between Russia and China is of great importance for both countries. Jiangsu University of Science and Technology is mainly located in the scenic and historic city of Zhenjiang, Jiangsu province. It is an engineering-oriented university with a competitive edge in three disciplines: shipbuilding, marine engineering and sericulture study. With its excellence at cultivating engineers, it is credited as being one of the best institutions by the Ministry of Education. With diligence, virtues, experience, and practice as its motto, and the Belt and Road Initiative as its mission, JUST is dedicated to the well-being of Chinese society and world development. With the aim of becoming more globally involved, JUST has launched various scientific and educational cooperative programs with its partners from many countries and regions, Including our MRSU university (We have been implementing a joint master’s degree program in the field of «Thermal Power Engineering and Heat Engineering» since 2016. In 2019, the program successfully passed state accreditation in both China and Russia).
