A group from Canterbury University is rewriting the normal relationship between students and beer with a undertaking that might stop 13,700 tonnes of waste going to landfill every year.
The undertaking, referred to as NanoBrew, hopes to use a biochemical course of to turn grain leftover from the manufacturing of beer into a extremely helpful material referred to as nanocellulose.
Team member Jade Wilson instructed Morning Report altering the way in which brewery waste, referred to as spent grain, is processed might considerably reduce carbon emissions.
“Grain is produced in quite large quantities and it spoils quickly. So, what ends up going to landfill is about the equivalent of 3,300 petrol cars being driven around for a year in terms of carbon emissions.”

Approximately 85 p.c of brewing waste is spent grain.
“The thing that we’re trying to get out of the spent grain is something called nanocellulose, which is essentially just a tiny little natural fibre, which has some really cool properties.
“It’s very robust, it is very versatile, and which means it may be utilized in a spread of actually thrilling functions from, biodegradable plastic alternate options to cosmetics to digital circuit boards.
The nanucellulose could possibly be utilized in cosmetics, biodegradable plastic alternate options and even digital circuitboards, and has a world market worth within the billions of {dollars}.
“What we’re doing is we’re just using these little proteins called enzymes to break down the grains and get that valuable nanocellulose,” Wilson mentioned.
“It’s quite difficult to compost. It ferments quickly and it’s quite wet, so there’s a lot of technical challenges there. Most of it goes to the landfill.”
The concept for NanoBrew got here from one in all its 10 members who was working at a neighborhood brewery, and had been wanting into the brewing course of and the waste concerned.
“We were really drawn to the opportunity to reduce that waste and some of the carbon emissions. It’s definitely a bunch of nerds involved, but we’re very passionate about how science can create impact in our communities,” she mentioned.
The NanoBrew undertaking is a part of the worldwide Genetically Engineered Machine (iGEM) artificial biology competitors. And, the group is fundraising to current its findings at a jamboree in Paris this November.
“The competition is centred around using science to solve issues that are impacting our global communities. We’re very excited to be representing New Zealand on the international stage,” Wilson mentioned.
