Chemistry in Grinding Jars

Solvents make up a large percentage of the waste generated by the chemical industry. Lars Borchardt can do without them altogether.

Typically, chemical reactions are carried out in solvents, which then have to be separated from the desired product, producing a lot of waste. Lars Borchardt’s team wants to get away from solvents: the researchers rely solely on mechanical energy. To this end, they use ball mills in which grinding balls collide like marbles, thus initiating chemical reactions. This eliminates waste and harbours potential for previously unknown reactions and products.

The project starts in 2020.
