Lumber, drywall, shingles, siding, flooring, cabinets, fencing, furniture, and ordinary household junk all load without trouble. The limits come from Indiana law and from what each local site accepts.
Indiana keeps whole waste tires out of landfills, with only narrow exemptions, and spent lead-acid batteries are barred from disposal as well. Open dumping and open burning are both illegal statewide, which rules out the old habit of burning construction scrap on site.
Hazardous waste never belongs in a container. Paint, solvents, fuel, motor oil, antifreeze, pesticides, pool chemicals, and asbestos all need separate handling, and so do liquids and sealed drums. The county district runs collection days through the year for exactly that material.
The county sites have their own refusals and they are strict. The district's yard waste centers take natural yard waste from county households only, and they refuse building materials, stumps, root balls, sod, and soil outright, along with anything from a business or a commercial operation. The recycling drop-off centers are household recyclables only. So a contractor cannot clear a site through either one, which is where a container earns its place. Ask your account manager about anything you are unsure of before it is loaded.
