Scientists Crack the Secret of Turning Beer into Gasoline
“Brewtroleum” doesn’t just fuel your car—it helps protect the environment as you drive.

Leave it to New Zealand to come up with the one, and only, instance where the combination of “alcohol” and “automobiles” is actually a good thing. There, local brewer DB Export has developed a new type of eco-friendly biofuel, the sin qua non for which is, yes, you guessed it—beer.
Okay, actually, the biofuel—dubbed “Brewtroleum”—isn’t made of beer itself (Sorry Homer). Rather, it comes from ethanol that’s been extracted from the slurry of brewing yeast left over after a batch of beer is made in DB Export’s breweries. The yeast would otherwise be thrown away, or sold to farmers as feed for their herds. Once the ethanol is refined out of the leftover yeast, it is combined with petrol to create the final, environmentally sound gasoline alternative.

DB Export has reportedly partnered with Gull Petrol stations to sell the Brewtroleum, believed to be the first commercially available biofuel of its kind. Per The New Zealand Herald, an initial batch of 300,000 liters, rendered from 30,000 liters of ethanol, is expected to last around six weeks, after having gone on sale across that country’s North Island earlier this month. Once the fuel runs dry, DB Exports will then assess sales to determine whether to release more onto the market. Explains company spokesman Sean O’Donnell: “It's a case of testing consumer demand and assessing the feasibility of ongoing production and logistics.”
Vicepoints out that not only is Brewtroleum ecologically friendly in and of itself, the fact that the ethanol comes from material that would otherwise be thrown away, as opposed to ethanol cultivated from specifically grown crops on farmlands which can end up leading to deforestation, makes it a doubly green innovation.
So while humans should never, ever, drink and drive, the fact that our cars are developing a taste for beer is a pretty good sign of ecological progress.
