Yijun Shi, Professor of Machine Elements

Published: 11 November 2021

Yijun Shi is driven by the desire to do something that benefits the environment and people. He has already come a long way by manufacturing a sustainable lubricant that has both won awards for its innovative and environmentally friendly technology, and entered an international market. His dream is to develop the new green lubricants that will be used in all cars and machines in the world in the future.

Lubricants protect components in the industry by reducing friction and thus saving energy and minimizing accidents. The oil-free product Sustainalube, which he developed together with his research colleagues, is completely renewable and based on glycerol, which is extracted using residual products from biofuels. It contains neither pollutants nor toxins and is used today mainly in the forest and construction industry, where leakage of lubricant is a major problem. Apart from the fact that there are environmental benefits, and that the process does not cause any carbon dioxide emissions, it is better and cheaper to produce than traditional lubricants. For this, he has received several awards, including the Future Award, which is awarded by Svensk Energi, Teknikföretagen and others.

Yijun Shi, born in 1981 in Jiangsu Province, defended his dissertation in 2007 at Nanjing University of Technology, with a dissertation on self-lubricating materials. He was employed at Luleå University of Technology in 2012 and came in contact with research at Tribolab, a lab that is unique thanks to its collaboration with industry and its world-leading measuring and testing equipment. In his spare time, he spends a lot of time with his family and his two children.
