Australian Brewery Young Henrys uses algae in beer production to help mitigate climate change

Australian brewery Young Henrys is fighting climate change by incorporating algae into beer production.

Since the fermentation process that occurs during beer production releases massive amounts of carbon dioxide, internally grown algae not only absorb CO2, but it produces as much oxygen as two and a half acres of the wilderness. , reported Food Tank.

“This is a one-time project and the goal is not to make a profit,” said Oscar McMahon, co-founder of Young Henrys. “It’s about creating something that we can then share with other people to adapt and use. “

Young Henrys signed this project with Sydney University of Technology in order to achieve carbon neutrality. Young Henrys uses two bioreactors to grow algae. The first is a control which contains CO2, oxygen and algae. The second contains the same three components, but is connected to a fermentation tank, reported Food Tank. As the fermentation process produces more CO2, the gas flows into the bioreactor.

At the end of each day, the control bioreactor consistently contains 50% less algae, McMahon reported. McMahon hopes that this system can not only reduce CO2 emissions from beer production, but also convert them to oxygen.

This specific project will continue for another year, Food Tank reported.

Young Henrys is currently experimenting with incorporating algae into foods, pharmaceuticals and bioplastics.

In order to increase algae production and develop new products, McMahon and Young Henrys are in consultation with engineering groups and the beer industry.

According to McMahon, the beauty of the algae and microorganisms used in the fermentation of beer are “yin and yang organisms, similar things that live in large reservoirs of liquid that do opposite but corrective work.”
