The Austin, Arlington, and Health Science Center campuses have comprehensive recycling programs for office waste. In Austin, 40 percent of paper, cardboard, cans, bottles, and other materials are diverted from landfills annually. In Arlington, 400 tons of such waste is recycled and 27 tons of landscape and food waste are composted. The Sustainable Food Center at UT–Austin is continuing to investigate food purchases that are locally grown or produced.
