Most building and household debris is fine to load. The limits come from South Carolina law and from what the county landfill will accept.
Electronics are the big one, and the rule is strict. In South Carolina it is against the law to put computers, monitors, televisions, printers, or any other electronic equipment, or parts of them, into a landfill, and it is equally against the law for the landfill to accept them. That ban covers construction and demolition debris landfills as well as household waste landfills, so a tear-out load is not exempt. One old television can get a whole load turned away. Greenwood County takes electronics at all nine of its convenience centers instead.
Tires, scrap metal, and used appliances are separate streams too. The county sends tires to a processing plant and sells scrap metal and old appliances for recycling rather than burying them, and city rules make a commercial user responsible for disposing of any appliance left behind by a trade.
Standard exclusions apply as well: hazardous waste, liquids, paint, solvents, fuel, used oil, and asbestos cannot go in a container. Greenwood also bars mixing yard waste with garbage and appliances at the curb.
If you are unsure about an item, raise it with your account manager before it goes in the container.
