Single-Stream Drop-Off

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.

Cardboard Boxes & Brown Paper Bags

Cardboard boxes and brown paper bags are collected in a separate bin. This helps reduce costs for transportation and processing.
