In an effort to create positive social and environmental impact, industry leaders Bühler, Covestro and Evonik (in previous years also Belimo, and Danfoss) joined forces to reduce the environmental impact of manufacturing and industrial processes. Students from across the world shared their ideas to fight global warming and climate change. The most innovative ideas were selected and the teams behind them gathered in Switzerland to develop and pitch their ideas to a jury from the consortium of companies. 2018 was the fourth year in which the challenge was run. Nearly 150 teams participated from all around the world, with 5 teams advancing to the finals. While each of the finalist teams were awarded prize money, Team Fresh Tag walked away with the title.
