Promoting a Circular Philosophy
How wastes is created, recycled or disposed of, both in our breweries and across our product life cycles, is an important driver of our products’ environmental impact. We are fully committed to see all of our major manufacturing facilities achieve zero waste to landfill by 2025. Currently, we reuse or recycle nearly 100 percent of our brewery waste including protein-rich residual brewer’s grain and spent yeast, glass cullet, aluminum, plastic, wood and other materials. We turn waste into energy, compost and soil conditioner for our own use. And we send the remaining byproducts to companies that use them for other beneficial purposes.
Being one of the largest brewers in the world gives us a uniquely powerful opportunity to make an impact on sustainable brewing. MillerCoors has remained an industry leader in waste reduction since its Trenton, Ohio, brewery reached landfill-free status in 2011. All MillerCoors major brewing facilities are zero waste to landfill.
MillerCoors is Landfill Free
By leveraging key learnings from our Trenton Brewery and the passion of its people to brew beer more sustainably, we have become landfill-free all seven of our major breweries. As of 2016, every MillerCoors brewery has earned landfill-free verification from NSF International, a global nonprofit public health organization. We are proud to recieve first beverage company to have all its major breweries verified as landfill-free by NSF International.
Achieving landfill-free operations at all major breweries is not the end of MillerCoors commitment to waste reduction. By 2025, our goal is to "achieve zero waste to landfill at all of our major manufacturing facilities."
Converting Waste Beer Into Fuel-Grade Ethanol
Since 1996, our Golden Brewery has partnered with a facility (owned by Merrick & Company) that produces more than 1 million gallons of ethanol per year. Ethanol is extracted from waste beer at the brewery through two stills. The end result is 200 proof, or essentially pure, ethanol. This pure ethanol is then mixed with gasoline to reduce automobile emissions. This process reduces the amount of wastewater treated at the wastewater treatment plant and reuses ethanol made at the brewery.
