by Phoebe French (The Drinks Business) The National Autonomous University of Mexico (UNAM) is using waste products from the wine and cheese industries to produce hydrogen and methane. Researchers working in the university’s engineering department in the Mexican state of Querétaro are undertaking the project. Led by researcher Germán Buitrón Méndez, the team is using grape marc and whey to create the two gases, which are then used to generate so-called clean electricity.
Buitrón Méndez said in a statement that the marc was collected from wineries in the local area (between the cities of Tequisquiapan and Ezequiel Montes) from June to November, while the whey is obtained throughout the rest of the year.
