Campus Composting Program

Composting bins that appeared in every dining hall this semester accept food scraps, napkins, compostable containers. The university claims they have diverted 40 tons of organic waste from the landfill in the first 3 months alone. Color-coded in green for compost, blue for recycling, black for landfill, with photographs above each bin showing what goes where rather than text. Photographs work better in a setting where people are making a split-second decision while holding a tray. Compost goes to a facility that turns it into soil amendment for the campus gardens. The closed-loop logic of eating food, composting the waste, growing more food is elegant even if the current scale is small. Learning that food waste in landfills produces methane, a greenhouse gas 80 times more potent than CO2 over 20 years, reframed composting from a nice-to-have into an urgent infrastructure need. Contamination is still high, about 15% of what goes in the compost bin isn't actually compostable. Dining staff sorts before sending it to the facility and the trend is improving as people learn. Monthly diversion numbers published by the university, plus compost output visible in the garden beds behind the science building, both reinforce trust in the program. My hall has a volunteer program where students serve as waste ambassadors standing by the bins during peak hours to help people sort correctly. Getting corrected by a peer is apparently the most effective education strategy. Bins smell worse than the other waste streams, which is a design problem the current ventilated lids only partially solve. Normalizing composting as a default behavior rather than an exceptional one is the program's real achievement. A generation that grows up sorting food waste in dining halls will expect it everywhere.
