When you rent a roll-off dumpster, the assumption is that you can throw pretty much anything in it. For the large majority of what comes out of a house, a remodel, or a job site, that's true. But every landfill operates under state environmental rules, and a short list of items is either banned outright or has to be handled separately.
Getting this wrong is not a small thing. A load with prohibited material in it can be refused at the scale, which means the container comes back to your property still full, and you are paying for a trip that accomplished nothing. Knowing the list up front takes about two minutes and saves that entire headache.
The items Texas landfills will not accept
These are the categories that cause almost every rejected load.
- Liquid paint. Dried paint is generally fine. Liquid paint is not, because it can leak through the container and contaminate the load. If you have partial cans, leave the lids off in a ventilated spot until the paint hardens, or mix in cat litter or a hardener product to speed it up.
- Automotive fluids. Motor oil, transmission fluid, antifreeze, brake fluid. These are classified as hazardous and have their own disposal channels.
- Tires. Texas regulates scrap tire disposal separately, and landfills track them by count. Most tire shops will take old tires for a small per-tire fee.
- Batteries. Car batteries especially, but also large lithium-ion packs. Auto parts stores routinely accept car batteries and often pay a core credit.
- Appliances containing refrigerant. Refrigerators, freezers, window air conditioning units, and dehumidifiers all contain refrigerant that has to be professionally recovered before the unit can be scrapped.
- Propane tanks and pressurized cylinders. Even an empty-feeling grill tank holds residual pressure. These are a genuine hazard in a compactor.
- Asbestos-containing material. Common in pre-1980 popcorn ceilings, floor tile, and pipe insulation. This requires a licensed abatement contractor, not a dumpster.
- Medical waste and sharps. Needles, lancets, and similar items need a sharps container and a pharmacy or clinic take-back program.
- Solvents, pesticides, and pool chemicals. The general rule: if the label carries a hazard warning and the container still has product in it, it does not belong in a roll-off.
Electronics are a gray area worth asking about
Televisions, monitors, and computers contain heavy metals, and rules around them have tightened over the years. Some facilities take them as ordinary bulk, some route them to e-waste, and some refuse them. This is the single most common item people are surprised about, so it is worth a phone call before you load a pile of old monitors into the container.
Most metro-area municipalities run free or low-cost e-waste drop-off days, and many big-box electronics retailers accept small electronics year-round.
Heavy material usually needs its own container
Concrete, brick, dirt, rock, and roofing shingles are not prohibited, but they are dense enough that they change how a container has to be loaded. A 20-yard container filled with concrete would be over the legal weight limit for the truck long before the box was full.
The standard solution is a dedicated heavy-debris container, loaded to a fill line rather than to the top. If your project is generating concrete or dirt, say so when you book, and you will get the right container instead of a surprise at pickup.
What happens if something prohibited ends up in the load
Usually one of three things. The driver spots it at pickup and asks you to pull it out, which is the best case. The scale house spots it and rejects the load, which means a return trip. Or it gets discovered during sorting and the disposal facility applies a contamination charge, which passes through to the rental.
None of these are catastrophic, but all of them are avoidable with a quick scan of the container before you call for pickup.
A practical way to handle it
Set aside a corner of the garage or driveway as a "not in the dumpster" pile before you start. Paint cans, batteries, that old propane tank, the tires that have been leaning against the fence for two years. Everything else goes in the container without a second thought.
Then handle the small pile in one trip. Most counties in the Fort Worth area run household hazardous waste collection events, and between an auto parts store, a tire shop, and a hazardous waste drop-off, that pile is usually gone in an afternoon.
Ask before you load, not after
The list above covers the common cases, but disposal rules vary by facility and they do change. If you are looking at something unusual - a hot tub, a piano, a fuel tank, a shed full of unlabeled chemicals - the fastest path is to describe it when you book the container.
At Sundance Disposal we would much rather answer that question on the phone than have a driver leave a full container sitting in your driveway. If you are planning a project in the Fort Worth area and you are not sure how to handle part of it, ask us before the container arrives.
