Ordinary building and cleanout debris is welcome. The restrictions come from Pennsylvania law and from the county authority that receives the load.
Pennsylvania keeps electronics out of landfills. The Department of Environmental Protection describes televisions, desktop and laptop computers, and monitors and peripherals as prohibited from disposal at municipal waste facilities. Pull them out before you load, or one old TV can sour the whole container.
The Greater Lebanon Refuse Authority publishes its own refusals. Its unacceptable items list rules out hazardous waste, liquid waste, explosives, radioactive waste, infectious and pathological waste, chemotherapy waste, covered electronics, and any waste generated outside Lebanon County. That last one matters if your project straddles a county line.
A few more practical limits. Hot ashes are flatly refused, and every open load has to arrive under a tarp. Refrigerators, freezers, air conditioners, and dehumidifiers carry a per-appliance charge for refrigerant removal, and tires are billed each, by size, with no rims allowed.
Paint, solvents, fuel, used oil, and asbestos stay out of any standard container. If you are not sure where something falls, check with your account manager before it goes in.
