Most household and construction debris is fine to load. Oregon's landfill bans and the county's own rules set the limits.
The Oregon Department of Environmental Quality says it's illegal to dispose of six kinds of items at a landfill: abandoned vehicles, large appliances, used oil, tires, lead-acid batteries, and computers, monitors, and TVs. People who haul their own trash can be held liable for disposing of them, so keep them out of your container.
The City of Roseburg adds its own warning list. Lithium batteries from phones, laptops, and tablets start most fires at local landfills and transfer bins. Hot ash, used fireworks, propane tanks, fire extinguishers, oily rags, paint cans, and chemicals also stay out.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos aren't allowed in a standard dumpster. The county handles asbestos only with a disposal permit.
Before you load something you're unsure about, check with your account manager.
