Clean up with coffee

It is an age-old problem, what to do with all the coffee waste. Coffee grounds usually just get dumped in the trash and taken away and that’s the last thought we have of them as they become someone else’s problem to dispose of. But scientists in Germany have found a new and innovative solution. They have made a disinfectant using coffee waste products.

Two German scientists working at the Jacobs University Bremen have found a way to turn coffee chaff, the skin of the coffee bean that is removed during the roasting of the beans and instead of using it as a compost have transformed it into another useful product, a usable and useful disinfectant. In spray form it could be another useful tool to keep hospitals and public transport clean and safe.
