Leftovers from beer brewing turned into biofuel

WASHINGTON — If your car could talk, it might ask for a round or two of this: biofuel derived from beer.

At the end of the beer brewing process, there is yeast left over.

Those leftovers have been turned into a biofuel that’s being sold for a short time at gas pumps in New Zealand.

Beer maker DB Export calls the fuel Brewtroleum.

Watch this funny video with a touch of science that details the process:

Although cleaner burning than regular gas, Popular Science reports Brewtroleum is 90 percent gasoline.

Another beer derived biofuel created by Molson Coors was pumped into cars used at the 2008 Democratic National Convention.

That stuff was just 15 percent gasoline.
