Brewery Makes Green Algae Beer to Creatively Combat Climate Change

Green beer. Green beer.

Young Henry’s Brewery in Australia is using green algae to make an environmentally friendly beer.

Oscar McMahon, the brewery founder, insists that even though there are tanks of bubbling algae, the algae is part of the production process.

“It never touches the beer. This is not green beer,”He stated.

Algae is a good example of this. The beer’s fermentation produces carbon dioxide, which is then released into the atmosphere. The algae prevents the greenhouse gas from entering the atmosphere.

“Basically, the CO2 is then ingested by the microalgae, which uses it to photosynthesize. That creates more algae, releases oxygen, and the world is a better place for it,”McMahon also adds

“For combating climate change, algae capture CO2 up to 400 times more efficiently than a tree,”Professor Peter Ralph, University of Technology, Sydney, explains.

The carbon dioxide produced by fermenting only enough hops to make six packs of beer used to take trees up to two days to absorb.

Young Henry’s beer isn’t just about fighting climate change. They are also researching another way that greenhouse gases can be released into the atmosphere.

The grain left over from the brewing process is used as cattle feed. The methane gas cattle produce in their farts and burps is reduced by adding algae to cow food.

According to Dr. Ralph many people will see more of algae or other substances in products. “eat” carbon.

“I think that’s going to be the future, where industries want to use recycled carbon, not fossil carbon.”
