Back in 1873, Rocky Mountain spring water put the Coors brewery in Golden, Colo., on the map for lovers of beer. Now, lovers of all things green will mark the facility as well: This week, the largest brewery in the country moved to landfill-free status.

The accomplishment, announced Monday, means that the 135 tons of waste the brewery generates each month is now recycled or reused. Spent grains, for example, are fed to livestock, while all paper, glass and pallets are recycled.
