Waste Reduction

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.

Waste-to-Landfill Performance

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 first brewery reached landfill-free status in 2011. 

MillerCoors Trenton, Ohio, Brewery was its first landfill-free location. Trenton’s best practices have provided the foundation for implementing landfill-free processes throughout MillerCoors other major breweries. Since 2009, MillerCoors has reduced its waste across the organization by 89 percent, equal to keeping more than 9 million pounds of waste out of local landfills.

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."

Coors Light Partners with Leave No Trace to Protect Nation’s Parks

Coors Light and environmental leader the Leave No Trace Center for Outdoor Ethics announced a new initiative in September 2018 to ensure parks across the country will be accessible and enjoyable for future generations through their program The Explore-Refresh-Protect Project. 

The Explore-Refresh-Protect Project will expand the reach of Leave No Trace’s scientifically-proven education practices and programs to areas in need across the country, called “Hot Spots.” Leave No Trace Hot Spots are areas suffering from the severe impacts of outdoor activities that can thrive again with Leave No Trace solutions. The result will be educational programs and tools, to put these Hot Spots on the road to a healthy recovery.

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.
