Single-Stream Drop-off Centers

Boulder County Drop-off Centers (DOC)  

Single-Stream recycling is a processing method used at the Boulder County Recycling Center that accepts recyclable materials in one bin. All recycling drop-off centers operated by Boulder County accept single-stream recycling with a separate box for Corrugated Cardboard and Brown Paper Bags.
