Composting 101

As part of our goal to reach Zero Waste by 2025, and per SB 1383, we are rolling out compost bins all across campus! All waste bin sets will include a landfill, recycle, and compost bin, except for those in office spaces and classrooms.

"In order to reach our campus goal, we all need to do our part in properly sorting our waste." - Marissa Acosta, Zero Waste and Sustainability Specialist
