UT Austin spent approximately 2 percent of its budget on locally grown food during the 2008-2009 academic year, and close to 6 percent on locally processed items. The university also purchases organic items, cage-free eggs, and hormone-free chicken. Vegan options are served daily. Customers receive discounts when they bring reusable bags and mugs. The Trash to Treasure Donation Drive collects unwanted items from students every spring.
