Can you recycle plastic bags in Boulder, CO?

Not in your recycling cart. Bags and film wrap around the sorting equipment at the facility City of Boulder uses, which is why they're excluded almost everywhere. Take clean, dry bags back to a grocery-store drop-off, or put them in your trash cart.

What do I do with batteries in Boulder, CO?

Batteries never go in any of your Boulder, CO carts — not the recycling cart, not the trash cart. They're household hazardous waste and a genuine fire risk in the truck. Tape the terminals and take them to a local e-waste or household-hazardous-waste drop-off.
