UMD strives to not only teach students about environmentally sustainable practices, but how to use them. There are 350 low-flow showerheads in residence halls to reduce water consumption. Roughly 65 tons of plastic, glass, tin, aluminum, paper, and cardboard are recycled from on-campus housing each year. Buildings are cleaned with Green-Seal® cleaning supplies and are painted with less hazardous paints to keep campus air quality high. UMD partners with the Minnesota Mattress Recycling Project to minimize landfill usage, and annual student furniture pickups keep neighborhoods clean and encourage re-use.
