"The University of Illinois – Urbana-Champaign spends 25 percent of its yearly food budget on locally grown or processed food items. Campus dining services also exclusively serve fair trade coffee and almost all seafood is sustainably harvested. The university is also very committed to reducing waste and has enacted efforts to recycle cooking oil for biodiesel production and currently a quarter of the meals served on-campus are trayless."
