Waste as an indicator is at the heart of sustainability in a practical measurable way

Our goal is zero waste

Sustainable schools use resources no faster than resources can be renewed. Sustainable schools generate wastes no faster than wastes can be absorbed into the ecosystem.

To become a sustainable school, Catlin Gabel School uses less and recycles, composts food waste, and purchases with end-of-use in mind to produce zero waste. Our  zero waste initiative launched in 2007-08.
