UNC strives to reduce waste going to the landfill by practicing campus-wide sustainable materials management and encouraging individual behavior change. In 2016, 47% of waste was diverted from the landfill. The Office of Waste Reduction and Recycling hosts events that encourage students to recycle, such as move-in and move-out donation drives and Residential Green Games. Carolina Dining Services also reduces waste by practicing food composting and recycling fryer oil to be used as biodiesel.
