A New Zealand Brewery Has Invented a Way to Run Cars on Beer Waste

DB Export Beer has dreamed up a new fuel for cars: ‘Brewtroleum,’ made from juice left over from the beer-making process

We’ve heard of cars that run on Champagne, motorcycles that run on bacon, and even airplanes that run on cooking fuel, but this has to be the first time we’ve heard of a car fueled by beer. DB Export, a brewery in New Zealand, has invented a new fuel called “Brewtroleum.” The fuel is made from the ethanol waste products of the beer-making process, and the brewery claims that it can power cars, according to Stuff.co.nz, a New Zealand news website.

If this really works, it could be a dream both for car manufacturers and environmental enthusiasts. After all, the ethanol produced by yeast and grain during the fermentation process will produce fewer greenhouse gases and leave less of a carbon footprint. DB Export claims that it is the world’s only “commercially available biofuel produced by beer.”

The commercially available part may be true, but after a quick Google search, we found that Cornell scientists already worked out a way to create biofuel from ethanol gases found in beer waste using a similar process back in 2012.


Brewtroleum is not yet widely available to the public; according to DB Export’s blog, “there’s still a little bit of work to do, but we’re confident we’re going to crack it.” However, to celebrate the invention, drivers in Auckland were invited to fill up their cars for free to test out the brew fuel. The first batch is expected to last six weeks, and consumers may see a wider rollout in later months.
