Most remodeling and cleanout debris is fine to load. The limits come from Texas rules and from what Hunter Ferrell Landfill will take.
The Texas Commission on Environmental Quality lets landfills accept scrap tires only after they've been split, quartered, or shredded. Whole tires should stay out of your container. The state also warns that some electronics, like circuit boards, batteries, monitors, TVs, and laptops, can test as hazardous waste, so recycling is the better route for them.
The landfill sets its own limits. It won't take chemicals or flammable materials such as gasoline, household cleaners, and pool chemicals. It also turns away any waste that looks hazardous, unidentifiable, or questionable. The usual exclusions apply as well, so keep out hazardous waste, liquids, paint, solvents, fuel, and asbestos.
For leftover chemicals, Dallas County runs a Home Chemical Collection Center, which you can reach at 214-553-1765. Appliances and scrap metal are recycled separately at the landfill, so tell us about them when you book.
If you're not sure about an item, ask your account manager before it goes in.
