Most building debris and household junk can go in your container. The limits come from California law and from Orange County's landfill rules.
CalRecycle lists the waste banned from the trash in California. The list includes batteries, fluorescent tubes, paint, solvents, antifreeze, motor oil, tires, and electronics like TVs and computers.
Orange County's landfills add a few rules. Tires aren't accepted at all. Treated wood, like old fence posts, isn't taken at the Olinda Alpha Landfill, and appliances are only accepted from residents, not haulers.
Hazardous waste, liquids, paint, solvents, fuel, propane tanks, and asbestos can't go in a standard dumpster.
If you're unsure about an item, ask your account manager before you load it.
