It's not a great idea to drink beer and then drive a car, but using beer to fuel a car is another story. That's happening in Auckland, New Zealand, where a chain of local filling stations is offering what it calls "Brewtoleum," reports the New Zealand Herald.
The 98 octane fuel is made by blending petroleum with ethanol that is extracted from leftover yeast used to make beer. The creation comes from DB Breweries, a Singaporean and Dutch company that operates in New Zealand. It claims the product is the world's first biofuel made from beer byproducts: "We're helping Kiwis save the world by doing what they enjoy best — drinking beer," DB spokesperson Sean O'Donnell told the Herald. Brewtoleum is available at 60 Gull service stations across the country.
The new fuel is another example of how beer can help the world, instead of just getting it drunk. Last month, a Chinese company developed a brew made with fake rhinoceros horn that aims to curb the poaching of rhinos.
