Disposal Rules
What Can Go in a Dumpster in St. Charles County
The working accepted and prohibited list for Wentzville and St. Charles County: what goes in a container without argument, what needs a second box, and what has to go somewhere else entirely.

The question comes in a dozen ways every week. Can I put the old deck boards in? What about the paint cans from the basement shelf? The pile of brush by the fence? The answer is usually yes, sometimes no, and occasionally “yes, but not in this container” — and the difference matters, because a load with the wrong thing buried in it becomes our problem at the scale and your problem on the invoice.
We have hauled out of Wentzville and across St. Charles County since 2015, and the list below is the one we actually work from. It is not a legal document. Landfill acceptance policies and county drop-off programmes change, so confirm the current rules with St. Charles County or your own municipality before you plan a big cleanout around them.
The short version
General construction and demolition debris, household junk and furniture are fine. Anything liquid, pressurised, toxic, infectious or containing asbestos is not. Yard waste is legal to generate and illegal to bury, so it travels on its own. Everything else is a detail.
What goes in without a second thought
The bulk of what we haul out of St. Charles County is ordinary construction and demolition debris, and there is very little argument about it:
- Framing lumber, sheathing, trim and offcuts — the standard output of a basement finishing job in Wentzville.
- Drywall and joint compound, whole sheets or scrap.
- Pressure-treated deck lumber. This one surprises people. Treated boards, joists, posts and railings go in a standard C&D container without special handling. What you must never do is burn them.
- Plaster and lath from the older stock around Pearce Boulevard, historic downtown Wentzville and Main Street in St. Charles — accepted, just brutally heavy at roughly two to three times drywall for the same volume.
- Brick, block, concrete and mortar rubble, including egress window spoil. These belong in a small container on their own; see our concrete and heavy debris service for why.
- Roofing — architectural shingle, underlayment, felt, flashing, and multi-layer tear-offs.
- Flooring of every kind: carpet and pad, laminate, vinyl plank, sheet vinyl, hardwood, ceramic tile and thinset.
- Cabinetry, countertops, vanities, interior doors and trim from a first-refresh kitchen or bath.
- Furniture, appliances without refrigerant, toys, boxes, clothing and general household junk — the whole contents of a basement, in other words.
If your load is mostly items from that list, you are in the clear and the only real decision is which dumpster size you need.

Yard waste: legal to cut, illegal to bury
Missouri bans yard waste from sanitary landfills. Grass, leaves, brush and branches cannot go in the ground under state law, which means they cannot go in a container headed to the landfill. They go to a composting or organics facility instead, as a separate clean load — not mixed in with the drywall and deck boards.
This trips up storm work more than anything else. After a straight-line wind event you have fence sections, soffit, shingles and a downed tree in the same yard, and the instinct is to fill one box with all of it. Do not. One container takes the building debris, another takes the wood. Our yard waste removal service exists precisely because the two streams cannot legally ride together, and the same split applies to storm and hail damage cleanup.
Be honest with yourself about the weight, too. Local tree debris here is oak, hickory, maple, sycamore, silver maple and Bradford pear. Green hardwood limb wood runs far heavier than people expect — a 15 yard box of fresh oak limbs is a serious tonnage, and a Bradford pear that split in a spring storm fills volume fast while still weighing plenty.
Prohibited outright
These do not go in any container we own, on any job, for any customer:
- Liquids of any kind, including wet paint, stain and sealer.
- Solvents, thinners, adhesives and strippers.
- Gasoline, diesel, kerosene, motor oil, transmission fluid, brake fluid and antifreeze.
- Pesticides, herbicides, fertiliser concentrate, pool chemicals.
- Propane bottles, oxygen and acetylene cylinders, fire extinguishers, and full aerosol cans.
- Batteries of all chemistries, and anything with a lithium cell in it.
- Medical, biohazard and infectious waste, including sharps.
- Tires.
- Refrigerant-containing appliances until a certified tech has evacuated them.
- Contaminated soil.
- Asbestos-containing material in any form.
Asbestos and lead in pre-1980 houses
St. Charles County has plenty of older stock, and pre-1980 construction routinely carries asbestos in places nobody looks: 9x9 floor tile and the black mastic under it, pipe and duct wrap on old basement ductwork and boilers, plaster skim coats, cement siding and roofing felt. Basements are where it turns up here, because that is where the old ductwork and the original mechanical room live.
We cannot take asbestos-containing material in a container under any circumstance. If the house predates 1980 and you are opening up ductwork, pulling old tile or tearing off original roofing, stop and have it tested. Missouri DNR runs the state asbestos programme, and demolition work generally triggers a NESHAP inspection and notification even when no asbestos turns up. Abatement is a licensed contractor's job and produces its own regulated waste stream.
Pre-1978 houses also fall under the EPA Renovation, Repair and Painting rule for lead paint, which governs how a paid contractor disturbs painted surfaces. The EPA publishes the current requirements. These programmes are amended from time to time, so verify the rules that apply to your project before the first sawzall cut rather than after.
The basement garage-and-workshop problem
Nearly every house here has a full basement, and a good share of them have a workshop corner and a shelf of chemicals that has been accumulating since the Clinton administration. Half-used latex and oil paint. A jug of motor oil. Antifreeze. A gas can with two-year-old mower fuel in it. Weed killer, bug spray, driveway sealer, a car battery, a milk crate of aerosols. None of it belongs in a container.
It all goes to a St. Charles County household hazardous waste drop-off. One point worth stating plainly: PaintCare does not operate in Missouri. There is no retail paint take-back scheme here, so do not drive leftover cans to a paint store expecting them to be accepted. The county HHW programme is the route. Dried-out latex paint with no liquid left in the can is generally treated differently from wet paint, but confirm the current handling rules with the county before you count on it.
Sort that shelf before we deliver, not after. It is the single most common reason an estate cleanout stalls halfway through, and it is why our home cleanout checklist puts chemicals in step one.
Pull the scrap metal first
Before anything goes in the box, walk the basement and the garage for metal. An old furnace and water heater, sheet metal ductwork, steel shelving, a treadmill or weight set nobody has used since 2011, deck railings and joist hangers, cast iron radiators, copper and aluminium. Metal is dense, it eats your weight allowance, and it has value as scrap. Pulling it out is free money and a lighter load in the same motion. Our notes on recycling and disposal in St. Charles County go into where the streams separate.
Electronics and CRT televisions and monitors are a related case — ask before they go in, because e-waste is often routed separately. Mattresses and box springs are usually accepted but frequently handled and charged on their own at the facility, so declare them up front rather than burying them in the middle of a junk removal load.
Railroad ties and burning
Railroad ties and creosote-treated landscape timbers turn up constantly on the acreage west and south of town — New Melle, Defiance, Foristell, Flint Hill. Creosote is a restricted material at many facilities. Tell us how many you have and we will confirm the route before the truck rolls.
And burning is not the answer. Outdoor burning is restricted or outright banned in many St. Charles County municipalities, including inside city limits in Wentzville, and rules differ block to block between incorporated and unincorporated areas. Pressure-treated lumber and creosote timber must never be burned under any circumstance — burning them releases the preservative chemistry straight into the air and leaves contaminated ash behind. Check your municipality's current ordinance before you strike a match.
What happens if prohibited material shows up
At the scale, loads get looked at. When something prohibited is spotted, the outcomes run in this order: a handling or sorting charge added to the ticket; the load rejected and returned, which means a second haul and a second tip; and in the case of hazardous or asbestos-containing material, a regulatory referral with penalties that land on the waste generator — the property owner — not on the truck. There is no version of this where hiding a can of thinner under the drywall comes out ahead.
The fix is a two-minute conversation. Tell us what the job is, what the house is, and what is on the basement shelf, and we will tell you what goes in, what needs a second container and what needs a different destination entirely. That applies whether it is a demolition debris job on an old outbuilding or a straightforward garage clearout.
