Lumber, drywall, shingles, siding, flooring, cabinets, fencing, furniture and everyday household junk all go in without fuss. The limits come from Indiana law and from what the county sites accept.
Whole waste tires are kept out of Indiana landfills but for narrow exemptions, and spent lead-acid batteries may not be disposed of either. Open dumping and open burning are both illegal statewide, so burning construction scrap on site is not an option, and the county recycling district says part of its own purpose is discouraging exactly that.
Hazardous material never belongs in a container. Paint, solvents, fuel, motor oil, antifreeze, pesticides, and pool chemicals all need separate handling, and so do liquids and sealed drums. The county runs collection days through the year for that material. Asbestos is licensed removal work and goes by a separate route entirely.
The county sites add their own refusals and they are strict. The recycling drop-off centers take clean, loose household recyclables only, and their published not-accepted list includes electronics, appliances, furniture, scrap metal, batteries, and food or yard waste. An attendant on duty can refuse any material. So separate out appliances and electronics before loading and tell us about them, because they are usually billed per piece rather than by weight.
