Ordinary rehabilitation debris loads normally: lumber, drywall, plaster, lath, roofing, flooring, cabinets, doors, windows, fixtures, furniture and general cleanout material.
Nothing hazardous belongs in a standard container, and nor do liquids, paint, solvents, fuel or asbestos. Asbestos deserves real care on Ottumwa's pre-war housing. It turns up in pipe insulation, floor tile, mastic and siding, and it has to be tested and removed separately before demolition.
Iowa bars several materials from land disposal: yard waste, baled solid waste, lead-acid batteries and waste tires. Whole tires cannot go into a sanitary landfill unless cut down to eighteen inches or less. So grass, leaves, branches, car batteries and tires all come out of the pile first.
The City's own ordinance also treats toxic and hazardous waste as outside its definition of solid waste altogether, so those materials are not a container question at all and need a licensed specialist route.
Appliances and electronics are generally priced per item rather than by weight, so set them aside and declare them when you book.
When one item is the thing you are unsure about, ask your account manager before it goes in rather than after the container is loaded.
