Most debris from a renovation, roof job, or cleanout is fine to load. The limits come from Virginia's landfill rules and from what the receiving landfill accepts.
Hazardous waste, liquids, paint, solvents, fuel, propane tanks, and asbestos can't go in a standard dumpster. Keep car batteries and motor oil out, too.
Virginia works a little differently from some states on electronics. State law makes computer makers run take-back programs, but it doesn't ban TVs or computers from landfills. Even so, recycling them is the better route, and it's worth mentioning any electronics when you book.
Tires and appliances with Freon usually need separate handling, so tell us about them before delivery. Virginia law also limits how many waste tires can be stored on a property without a permit, so don't let a tire pile build up while you wait for pickup.
