Most household junk and building debris can go in a dumpster. The Ada County Landfill says construction and demolition waste, yard waste, and household trash can all go in the landfill.
The limits come from the landfill's rules. The Ada County Landfill doesn't take hazardous waste, which includes anything flammable, corrosive, explosive, reactive, or toxic. Asbestos needs a certification before it can be disposed of. Refrigerators, freezers, and air conditioners that hold Freon are charged per item because of the special handling.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos can't go in a standard dumpster.
The landfill has a separate recovery area for appliances, metal, electronics, clean wood, and tires, so tell us about those items before you load them.
If you're unsure about anything, check with your account manager first.
