Framing, drywall, roofing, flooring, carpet, cabinets, doors, siding, brick and block are all normal Chapel Hill loads. Two separate sets of limits apply.
The first is state law. The North Carolina Department of Environmental Quality keeps used oil, yard trash, large appliances, antifreeze, aluminum cans, whole scrap tires, lead-acid batteries, oil filters, recyclable rigid plastic containers, oyster shells, discarded computer equipment and televisions out of landfills statewide. One line matters more here than almost anywhere: fluorescent lights and mercury thermostats are barred from unlined landfills, and in North Carolina every construction and demolition landfill counts as unlined. Chapel Hill debris goes to a construction and demolition landfill, so old tubes and thermostats have to come out first.
The second is the county's own refusal list at the gate. The Orange County Landfill takes no household trash, no furniture, no mattresses and no building cleanouts, refuses asbestos shingles, and will not take metal plumbing fixtures or metal pipe in a construction load, because those belong in the scrap metal stream.
Hazardous waste, liquids, paint, solvents, fuel and asbestos stay out of any standard container. If you are unsure about an item, ask your account manager before it goes in.
