Australian beer makers struggle local weather change by feeding carbon to algae

Australian beer makers have brewed up a novel strategy to struggle local weather change: capturing the carbon dioxide produced by fermenting hops and feeding it to micro-algae.
The carbon emitted by fermenting hops to make a six-pack of beer can take a tree two days to soak up, specialists say. To deal with that drawback, the founders of Young Henrys brewery in Sydney teamed up with scientists to arrange two “bioreactors” stuffed with trillions of the tiny organisms.

Inside the 2 400-litre bioreactors on the firm’s brewery in Sydney, the algae soak up the carbon, then reproduce and rework it into oxygen. Each bioreactor produces as a lot oxygen as two hectares of bushland, Young Henrys co-founder Oscar McMahon instructed Reuters.

“We could knock down our whole site and plant trees, and … it would take years before they did the same amount of carbon sequestration and oxygen creation as those two bioreactors,” McMahon instructed Reuters. “As an urban carbon sequestration and oxygen producing solution, it’s mind-blowing.”
The Young Henrys staff, the scientists from University of Technology, Sydney have additionally joined business group Meat & Livestock Australia to research whether or not the algae may very well be used to offset the methane emissions of Australian livestock.

“Instead of us digging something up, making a product and then throwing it away, we circularise it and we’re actually going to use our carbon effectively,” mentioned Professor Peter Ralph, the chief director of the Climate Change Cluster on the UTS.
Australia, one of many world’s high producers of coal and fuel, has adopted a goal of internet zero carbon emissions by 2050, however Prime Minister Scott Morrison has mentioned he wouldn’t legislate the goal.
