Most debris from a remodel or cleanout can go in the container. Oregon's landfill rules and the facility that takes your load set the limits.
The Oregon Department of Environmental Quality lists six things that are illegal to dispose of at a landfill or transfer station in Oregon. They are vehicles, large home or industrial appliances, used oil, tires, lead-acid batteries, and computers, monitors, and TVs. DEQ says people who haul their own trash can be held liable for dumping them.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos don't belong in a standard dumpster either. Gresham's code also asks customers to keep chemicals, corrosive materials, medical waste, and hot ashes out of drop boxes.
Most banned items still have a recycling route, often for a fee per item. Pull out appliances, tires, and electronics, or list them when you book.
If you're unsure about an item, ask your account manager before it goes in.
