A brewery in Sydney, Australia is getting creative with the carbon dioxide emissions produced by yeast during fermentation. Young Henrys, with the help of a local university, is feeding those fermentation gases into tanks of native river algae that turn that CO2 back into oxygen. This process neutralizes the emissions. The CO2 produced to make one six pack of beer would take a tree two days to absorb.
“You have this really amazing yin and yang scenario,” said Oscar McMahon, Young Henrys co-founder. “One tank of algae is capable of creating the equivalent amount of oxygen as one hectare of Australian bush. It takes a long time to grow that, whereas we can grow a tank of algae within weeks.”
