Zero Waste

What Goes in Each Bin?

CSUN's new interior waste bins were made possible through a grant from CalRecycle. The goal is to replace all indoor communal waste bins with a new three-stream system to enable proper waste sorting and divert more material from the landfill. Explore the guides below to learn how this new system impacts waste handling processes on campus.

Why have the bin colors changed?

CSUN is changing the color of its recycling and organics streams to match the City of Los Angeles' curbside bin colors. Green (formerly bottles and cans) now represents compostable/organic items. All recyclable are now comingled in the blue bin, and landfill waste goes in the black bin. This change was also made in anticipation of upcoming requirements by CalRecycle that would standardize bin colors for waste streams statewide.

Some large cardboard boxes won't fit in the new recycling bins, what should be done with those?

Cardboard boxes should be flattened and placed behind or next to the recycling bin. If you have 5 or more boxes, you can contact Associated Students at x4262 or email to arrange for them to be picked up.

What about other recyclable items, such as ink cartridges and personal electronics?

These unconventional recyclables are still processed by Associated Students. Call extension x4262 or email to arrange a pickup, or drop them off at the Sustainability Center.
