Bin locations

Centralized compost collection bins are available in all three residence hall areas for students who wish to collect and dispose their organic waste for composting. Click on area for organic waste collection locations: Cuarto, Segundo, Tercero.

Compost collection bins are not provided in residents’ rooms. Any container with a lid can be used to collect organic waste. A coffee can with a lid, disposable food container (such as a large yogurt container) and cardboard oatmeal containers used with a liner are just a few examples. Containers can also be purchased at local retail stores. Residents are encouraged to empty compostable containers regularly.

Where does it go?

The organic waste collected in Student Housing and Dining Services is sent to the commercial composting facility Northern Recycling Compost Facility in Zamora, Calif. The facility recycles green material, food waste, wood waste, and agricultural waste to provide compost, mulch, biomass fuel, and value-added soil and compost blends.
