Global demand for biofuels is set to grow by 28% over 2021 levels by 2026, or about 41 billion litres, according to the International Energy Agency.
WD News: Plastic, cow poop, beer wastewater – you name it, and researchers are working with it to create alternative biofuel products. Biofuel is a fuel derived directly from living matter, and is being used more and more to potentially replace fossil fuels.
Researchers at the University of San Diego in California are developing an unlikely mixture to help power the future. They are taking beer wastewater from Stone Brewing and mixing it with kelp and fish or sheep waste to create a new sustainable fuel option.
Stone Brewing supplied 14 litres of reclaimed beer wastewater to the research team. Last year, using an on-site water reclamation system, they reclaimed more than 11 million gallons of wastewater.
They are using mini anaerobic digesters for the fuel creation process. They got the idea from a similar project in Barbados, where researchers are combining rum wastewater, sargassum (or seaweed), and sheep waste.
