Turning By-product from Brewery into Biofuel
In the past, we have highlighted companies like (B)Engery and Daily Dump, that uses organic waste to make biogas and compost respectively. Similarly, DB Export, a brewery in New Zealand, is utilizing the yeast and grain leftover after brewing their beer to make biofuel.
The by-product of brewing beer, a yeast slurry, which would normally be thrown out or used as livestock feed, is sent to a lab which turns it into ethanol. The ethanol is then mixed with regular petroleum and sold as biofeul. They are not the first to make biofuel from leftover yeast, but certainly the first to successfully make it available to the public. Their “Brewtroleum” as it is called is now available at the pumps at Gull New Zealand.
Alone, this could very well be a marketing stunt but if all other breweries utilized their leftover waste to produce ethanol, it would definitely add up to something. We do drink a lot of beer in our part of the world. Would it be smart to capitalize the leftover yeast and grain to produce ethanol?
