Brewtroleum was created by beer company DB Export, which has been testing the product since February.
"Brewtroleum was an idea sparked over a few beers, which presented the opportunity to take the natural by-product of the brewing process and turn it into something that can genuinely help the environment," said DB's head of domestic beer marketing Sean O’Donnell. "What’s more, men can help to save the world just by doing what they already love – drinking DB Export.”
During the process, scientists extract high-grade ethanol from the yeast slurry byproduct that would otherwise go to waste. After this, the ethanol is distilled and then blended with high-octane petrol (10 percent ethanol and 90 percent petrol) to create bioethanol capable of running a car's engine.
DB Export was reportedly searching for commercial partners just last week. Gull is the first to jump on board.
This makes sense, as while DB Export has technically accomplished a New Zealand first by distilling a biofuel composition from beer, it's following in the footsteps of Gull, which started production of dairy-wastage based biofuel in 2007. The fuel provides a slightly more environmentally friendly means to power automobiles.
Rather than adopting humility in promoting this undeniably impressive feat, DB Export has released a series of ads that make the bold claim that this move could literally save the entire world—as well as the dolphins and pandas that inhabit it. It says biofuel, such as the Brewtroleum, can reduce carbon emissions by 8 percent.
DB Export will initially release 300,000 litres of Brewtroleum made from 30,000 litres of ethanol. Over 58,000 litres of yeast slurry (what's leftover from the beer brewing process) contributes to making the ethanol.
The yeasty concoction is due to be unveiled at Gull Kingsland this morning, and then will be rolled out to 60 of its service stations across the North Island from today.
