Most construction and household debris is fine. The limits come from state law, city code, and what the county landfill will accept without a penalty charge.
South Carolina puts the electronics duty on both the person throwing the item away and the landfill taking the load. State law tells consumers not to discard a covered device into waste headed for a landfill, and tells the landfill operator not to accept loads holding more than an incidental amount of them. Take televisions, monitors and computers out before the container is hauled.
Used oil has a flat statutory ban. State law bars anyone from knowingly putting used oil into municipal solid waste. Waste tires, lead acid batteries, yard trash and large appliances are all handled separately rather than buried, and the Solid Waste Authority says plainly that yard waste is banned from South Carolina landfills by state law.
Hazardous material of every kind stays out: gasoline, oils and grease, poisons, acids, caustics, chemicals, explosives and highly flammable material are all defined as hazardous refuse in city code and barred from any collection container. Liquids have to be drained before anything goes in.
A few local specifics are easy to miss. The city does not collect tires at all. It does not haul trees, logs or stumps from tree removal, which stays with the property owner or the contractor who did the work. And residential bulky item pickup expressly excludes building materials, roofing, soil, rock and concrete, which is exactly the material a container is for.
If an item is borderline, ask your account manager before it goes in. The county's contamination and prohibited load charges make that a cheap phone call.
