Can drinking more beer, save the planet? That's what a beer brewery in New Zealand is saying.

According to various reports, DB Export, a brewery in New Zealand, announced last month it had created a biofuel made using leftover yeast from brewing beer called "Brewtroleum."

The NZ Herald reports that the company recycles yeast slurry, which would otherwise be thrown out or given to animals, and turns it into ethanol that can be mixed with regular petroleum fuel.

This isn't particularly revolutionary, as fuel comprised of 10% ethanol and 90% petroleum (E10) is already very common, but DB claims it's the first time that commercially available E10 has been made from beer by-products. The company believes that MillerCoors was the first to make fuel from beer by-products, but DB is the first to make it public.

According to Mashable, a company spokesperson said its 98 octane E10 is theoretically no different than any other E10, though DB argues its is more fun to make.

E10 is sold as a greener, more sustainable alternative to pure petroleum fuels, but these claims have attracted much debate. A 2013 investigation from the Associated Press found the increased corn production to make ethanol in the U.S. caused great environmental harm and drove up the cost of corn at the supermarket.

Sources say there is also debate about the performance effects of gas with ethanol mixed in, especially in E15, which uses a mix of 15% ethanol and 85% petroleum.

DB Export's Brewtroleum is a stunt, but maybe they're on to something by using the yeast leftover from beer production.
