New Zealand drivers can now fill their cars up with a fuel made using beer byproducts, reports The Independent.  

Brewtroleum, a term coined by its makers, creates up to 8 percent less carbon dioxide than regular fuel and is the first commercial fuel made from brewing byproducts, according to Gull Fuel.

Gull Fuel and DB Export brewers created 300,000 liters  (79,252 gallons) of the biofuel by extracting 30,000 liters (7925 gallons) of ethanol from 58,000 liters (15,322 gallons) of yeast slurry that would have otherwise been thrown away or given to farm animals.

If the first 300,000 liters of Brewtroleum prove successful, its makers may consider producing more of it in the future, according to Gull Fuel.
