The U.S Environmental Agency estimates that over 12 percent of our trash is made up food waste that, instead of being composted, is sent to the landfill. Most on-campus USC eating facilities, inlcuding dining commons, restaurants, and cafes, compost their food scraps. USC Facilities Management Services is responsible for the compactors and bins designated to collect this food waste. In calendar year 2009, 100% of the food waste retrieved from these compactors and bins -- more than 338 tons -- was composted. These 338 tons help reduce waste sent to the landfill and the resulting methane production- a greenhouse gas 21 times more potent than carbon dioxide!
