Most household junk and construction debris can go in your container. The limits come from the Teton County Trash Transfer Station, which receives Jackson's trash.
The transfer station won't take asbestos, liquid waste, or electronics like TVs, computers and phones. Batteries are refused too, including car batteries and lithium batteries. So are bear spray, propane canisters and other compressed gas cylinders, and fluorescent bulbs. Household hazardous waste, such as antifreeze, oil-based paint, turpentine, used motor oil and pesticides, goes to the county's seasonal drop-off by appointment instead.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos don't belong in a standard dumpster either. Demolition debris needs an asbestos test before it can be dumped. Concrete and masonry chunks must be no bigger than two feet on a side, with rebar cut flush.
When you're unsure about an item, check with your account manager before you load it.
