In an effort to find a more sustainable energy source, a New Zealand brewery is using beer as a green fuel available at pumps across the country. DB Export Brewtroleum is helping consumers move away from a reliance on petroleum by offering an alternative made partially out of natural beer waste. The product is currently available at select Gull Service Stations as part of a special partnership.
The biofuel is made by distilling leftover yeast, which is from the brewing of DB. The result is 95% pure ethanol that can be used as green fuel. This releases less greenhouse gases compared to regular gas and also reduces waste produced by the brewery in their processes.
