Fuel your car with beer in New Zealand

New Zealand just took one step closer to becoming a complete utopia, where smiles function as money and drinking beer counts as environmental activism. Starting today, drivers can fill their cars with DB Export Brewtroleum, a biofuel made with the yeast leftover from brewing beer.

Simon Smith, a spokesman for DB Export—the New Zealand brewery that created the biofuel—told VICE it’s actually pretty easy to turn beer into something that can run a car. So easy that “a few guys having a few beers” came up with the idea back in February. Six months later, the biofuel is being pumped at Gull Petrol Stations across New Zealand.

Here’s how the process works. When brewing beer, there’s always a bit of sediment left once the drink has fermented. It’s mainly made up of inactive yeast, and people in the brewing business call it slurry. Usually, as Simon explains, “The yeast slurry is passed on to farmers for stock feed, but sometimes it can go to waste.”

The DB Export folks realized the slurry could still be used to produce ethanol; a key ingredient in biofuel. So instead of dumping it, they sent 15,300 gallons of slurry to a refinery. There, the ethanol from the yeast was refined until it was pure enough to start mixing with petrol. Simon explains “Brewtroleum is 10 percent ethanol from our yeast, and 90 percent petrol.” That’s the same ratio as the E10 at your local service station, which almost all modern cars can run on.

DB Export made 79,250 gallons of biofuel, which Simon expects to last about six weeks, but he says a second batch might be on the cards. “It’s gone off with a bang, so we’ll just see how people enjoy it.” In fact, one of Gull’s Auckland employees reported people turning out in droves for Brewtroleum’s launch, making it their “busiest day of the year, so far.”

Despite the hype, biofuel itself isn’t always the holy grail of sustainability, so there’s a little bit more to consider. As Professor Peter Scales from the University of Melbourne warns, not all biofuels are created equal.

Moeraki Boulders

The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach on the wave-cut Otago coast of New Zealand between Moeraki and Hampden. Moeraki Boulders New Zealand 08They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve. The erosion by wave action ofmudstone, comprising local bedrock and landslides, frequently exposes embedded isolated boulders. These boulders are grey-colored septarian concretions, which have been exhumed from the mudstone enclosing them and concentrated on the beach by coastal erosion.[1][2][3][4]
