Behind every steaming cup of coffee there is a great environmental challenge: what to do with millions of tons of polluting waste. An Argentine scientist based in the United Kingdom and his Colombian colleague found a possible answer to the problem: transform coffee waste into electricity. These wastes have already been used to produce biofuels, but it is the first time they have been used to generate electricity.
The research is the product of the collaboration of Claudio Avignone Rossa, a professor at the University of Surrey, in England, with Lina Agudelo, from the University of Antioquia. Both say that using coffee waste to produce electricity could not only reduce the problem of pollution, but help financially to coffee farmers.
