Longtime MillerCoors brewery employee Kelly Harris was a driving force in the efforts. As a shop floor technician, Harris noticed small process changes could lead to large waste reductions. After conducting research, he developed and implemented a waste-reduction business plan that in 2010 led MillerCoors Trenton, Ohio, brewery to become the company's first landfill-free facility and the world's first zero waste mega-brewery. Three other MillerCoors breweries – Shenandoah, Irwindale, and Eden – have also achieved landfill-free status. "There's a misperception that sustainable manufacturing is expensive, but employee behaviors are really the key to efficiently and affordably making the change," Harris said. "Working alongside brewery leadership, we developed a way to do things differently and implemented new manufacturing processes at the brewery. We've proven that there's an alternative place for all waste, even at one of the world's largest breweries."
