How can drinking beer help clean Chicago’s water?

<p>Josh Deth, founder of <a href='https://revbrew.com/'>Revolution Brewing,</a> talks about the basics of beer brewing and how it can be sustainable. In addition to using solar energy, recycled packaging, and rooftop beehives, Josh discusses what they do with the byproducts of the brewing process. He says spent grain is the number one byproduct, and the protein-rich hops can be used to feed cattle. Josh also explains how his brewery's byproducts help clean the city's wastewater and how the spent yeast and hops become part of the Metropolitan Water Reclamation District's treatment program. </p> <p> </p>
