What Can and Cannot Go in a Dumpster in Colorado?

A roll-off dumpster handles most of what a renovation, cleanout or construction project generates, but a specific list of materials is banned from every container we run — some because they are dangerous to haul and dispose of with general debris, others because Colorado and federal law require separate handling. Here is the straightforward version.

What's allowed

• General household junk: furniture, boxes, clothing, toys, décor
• Construction and renovation debris: wood, drywall, flooring, trim, cabinetry
• Roofing debris: shingles, underlayment, flashing
• Yard waste: brush, limbs, dead turf, small stumps
• Concrete, brick, tile and similar masonry (priced separately by weight)
• Non-refrigerant appliances

What's banned from every container

• Paint, solvents and adhesives
• Motor oil, fuel and other petroleum products
• Tires
• Batteries of any kind, including car batteries
• Propane tanks and other pressurized gas cylinders
• Medical and biohazard waste
• Asbestos-containing material (without prior testing and licensed handling)
• Refrigerant-containing appliances (unless certified refrigerant-free)
• Ammunition and firearms

Why these items are banned

Some banned items are dangerous to compact or transport — pressurized cylinders and batteries can rupture or ignite under the weight of a full load. Others are regulated because they contaminate landfills or require specific processing — paint, solvents and fuel are classic examples, and refrigerant has to be recovered before an appliance goes to a shredder rather than vented into the atmosphere. Asbestos is regulated because disturbing it without proper containment is a genuine health hazard, not just a disposal inconvenience.

Where prohibited items actually go instead

The Colorado Department of Public Health and Environment (CDPHE) publishes current guidance on household hazardous waste disposal, including periodic collection events and permanent drop-off options in the region. Tires and batteries are usually accepted at auto parts retailers or dedicated recycling points. Paint can often be dried out and disposed of as solid waste once fully hardened, or taken to a paint-specific recycling program where available. If you are not sure where something belongs, call us — we deal with this question regularly and can usually point you the right direction even for material we cannot personally haul.

What happens if something prohibited ends up in your load

If our crew finds prohibited material in a container, it has to be pulled and disposed of correctly before the rest of the load can be processed, and that removal cost is charged back to the rental. It is always cheaper and simpler to keep these items out from the beginning — a five-minute sort at the curb saves a real cost later.
