In Maine, Colby College’s sustainability programs extend to the school’s dining halls, which spent 20% of their budget on local products in 2005. One dining hall regularly has more than 20 organic items on the menu. In addition, Colby is committed to purchasing only sustainable seafood, has eliminated paper cups from the dining hall, and has implemented a just-in-time strategy so that food is cooked to order, thereby reducing pre-consumer waste by 80%.
