Most household and construction debris is fine to load. The limits come from Georgia's rules and from what the transfer station accepts.
Liquids are the big one. Georgia's Environmental Protection Division notes that garbage trucks can't pick up liquid waste, so leftover paint, solvents, fuel, and chemicals must be dried out or taken elsewhere.
Georgia also wants yard trimmings kept out of landfills and returned to the soil. Brush and leaves should go to a yard waste site, not mixed with construction debris.
Hazardous waste and asbestos can't go in a standard dumpster. The county transfer station charges extra for tires, mattresses, propane tanks, paint cans, and appliances with Freon, so list those items when you book.
If you're unsure about an item, ask your account manager before loading it.
