Brewers everywhere are excited about the potential of spent grain, the leftover grains used in beer-making, to be more sustainable. A new study by researchers at the University of Massachusetts Amherst has found that spent grain can be used to create a sustainable energy source, potentially cutting down on the amount of waste produced in the brewing process. By combining spent grain with seaweed and other byproducts, the researchers were able to create a fuel-like material that can be used to generate electricity and heat. The researchers believe this could be a viable and sustainable energy source for the brewing industry.
