The chemistry of halogens is part of the cycle in the fabrication of multiple chemicals. That alone explains the importance of having a closed halogen loop so this process occurs in an efficient and sustainable manner. That “recycling” idea is what Prof. Javier Pérez-Ramirez (aCe Catalisys Engineering at ETH Hönggerberg) wanted to picture in this image, which made it to the cover of Chemical Reviews.
