Prohibited Items & What Can’t Go in a Dumpster

S&A Container Service

Quick Answer Summary

As a general rule, if it is liquid, flammable, toxic, or contains hazardous chemicals, it cannot go in a dumpster. Prohibited items fall into two categories: Hazardous Materials (which are never allowed) and Special Handling Items (which require a separate quote or specific loading instructions).

Tossing prohibited items into a container can result in “Dig-out Fees,” where the driver must empty the load to retrieve the item, or heavy fines from local transfer stations.

Common Garage & Shed Items People Forget About

One of the biggest mistakes we see during garage, basement, and estate cleanouts is customers accidentally throwing away old chemicals that have been sitting on shelves for years.

Common examples include:

Old gasoline cans
Oil containers
Pool chemicals
Weed killers & pesticides
Paint thinners
Automotive fluids

Even if the containers are old or nearly empty, they are still considered prohibited materials and should be separated before loading the dumpster.

Pro Tip: Dry Out Small Liquid Residue Before Disposal

Small amounts of leftover paint or residual gasoline inside old lawn equipment, containers, or cans should never be placed directly into a dumpster while still in liquid form.

For small residual amounts only, absorbent materials such as kitty litter or oil-absorbent products like Speedy Dry can help solidify the liquid before proper disposal.

Any larger quantities of gasoline, oil, paint, or chemicals should always be separated and brought to an approved hazardous waste collection facility.

Special Handling: Call Before You Toss

Some items aren’t “hazardous” but are regulated differently by local municipalities. We can often take these, but they must be declared and may incur an extra fee:

1. Appliances (White Goods)

Refrigerators, freezers, and AC units contain Freon (refrigerant gas). By law, this must be recovered by a professional before disposal. We cannot accept units that still contain Freon.

2. Electronics (E-Waste)

Items like “old school” CRT monitors, flat-screen TVs, and computers contain heavy metals. Many local towns require these to be recycled at specific e-waste hubs rather than mixed with general construction debris.

3. Tires

Tires are “trapped air” hazards at landfills; they tend to float to the surface of a landfill cell and pop liners. We can sometimes take tires for an additional per-tire fee, but they cannot be buried at the bottom of the container. Larger commercial, equipment, or oversized truck tires may carry significantly higher disposal fees than standard passenger vehicle tires, so it is always best to confirm tire quantities and sizes before loading the container.

4. Mattresses & Box Springs

Many local transfer stations now charge a high “unit fee” for mattresses because they are difficult to crush and clog up recycling machinery. Always let us know if you have more than one. Disposal fees are typically charged per mattress or box spring regardless of the overall dumpster weight, so it is important to mention larger quantities ahead of time.

Pro Tip: Always let us know ahead of time if your load includes mattresses, box springs, or tires so pricing and disposal requirements can be confirmed before pickup.

Railroad Ties, Docking Lumber & Treated Wood Materials

Railroad ties, dock pilings, bulkhead materials, and certain pressure-treated lumber products often require special handling and should always be discussed before loading a dumpster.

Many of these materials have been exposed to preservatives, saltwater environments, creosote, or older treatment chemicals such as Chromated Copper Arsenate (CCA), which can affect how the material is handled, transported, or disposed of at transfer stations and recycling facilities.

Because disposal requirements can vary depending on the material type, age, condition, and local regulations, it is always best to confirm these materials in advance before loading the container.

The Paint Question

This is our most common FAQ. Can you put paint in a dumpster?

NO: If the paint is liquid. It will leak out of the truck and create a chemical trail down your street, or leak into your driveway
YES: If the paint is completely dried/solidified
The Trick: Mix kitty litter or “paint hardener” into the cans. Once it is a solid block, leave the lids off so our driver can see they are dry.

How to Avoid Fines & Fees

Issue	Potential Result	Prevention
Hidden Hazard	$250+ “Load Rejection” Fee	Check old garage shelves for chemicals before clearing them out.
Leaking Liquid	Environmental Cleanup Fine	Never put wet paint, oil, or chemicals in the bin.
Overweight Bin	Overage Charges	Use our Dumpster Weight Guide for heavy materials like dirt or concrete.
Prohibited Item at Scale	Reload or additional per item disposal cost	Be specific about items you’re disposing of and call to ask any questions if you’re unsure.

FAQ: Prohibited Items

What should I do with my hazardous waste?

Most local towns host “S.T.O.P.” (Sovereign Toxics On Premises) days or hazardous waste collection events throughout the year. These are free for residents to drop off oil, chemicals, and pesticides.

Can I put a propane tank in if I leave the valve open?

No. Propane tanks are pressurized vessels and are strictly prohibited from all standard roll-off containers due to the risk of explosion during the compaction process at the landfill.

Will I be charged if a neighbor throws trash in my bin?

Unfortunately, yes. As the permit holder/renter, you are responsible for the contents of the container. If you are in a high-traffic area, we strongly recommend keeping the dumpster covered with a tarp overnight to help discourage unauthorized “drive-by” dumping from neighbors, pedestrians, or nearby contractors.

Whenever possible, it is also best to have the dumpster placed farther onto the property and in a well-lit area rather than directly near the street. This can help reduce unauthorized use and make the container easier to monitor during longer projects or overnight use.

What Waste Is Strictly Prohibited?

The following items are hazardous to the environment and our drivers.Local and Federal Department of Environmental Control and Town laws prohibit these from being landfilled:

Flammable & Volatile Liquids: Gasoline, motor oil, propane tanks (even empty), kerosene, and paint thinners.
Toxic Chemicals: Pesticides, herbicides, pool chemicals, and industrial cleaners.
Biohazardous Waste: Medical waste, needles, and animal remains.
Lead-Acid Batteries: Car batteries and large UPS backup batteries.
Asbestos: Asbestos materials require a specialized abatement hauler, categorized as either friable or non-friable depending on how easily they release fibers. Friable materials, like insulation, can be easily crumbled by hand and pose an immediate inhalation risk, while non-friable materials, like shingles or floor tiles, are tightly bound and generally only release fibers if damaged or broken.
Radioactive Materials: Smoke detectors (which contain small amounts of Americium-241) should be mailed back to the manufacturer.
Asbestos: There are two types of asbestos-containing materials: friable and non-friable.

Friable asbestos materials can be easily crumbled, pulverized, or reduced to powder, which can release hazardous airborne fibers during handling or demolition. Non-friable asbestos materials are generally more stable and are not easily reduced to powder under normal conditions, but they can still become hazardous if broken, cut, sanded, or otherwise disturbed.

Common asbestos-containing materials may include older roofing materials, floor tiles, insulation, siding, pipe wrap, plaster, and wallboard products.

Because asbestos regulations and disposal requirements can vary depending on the material type, condition, and local regulations, asbestos-containing materials should never be placed into a standard dumpster without first confirming proper handling and disposal requirements.

What’s the Difference Between Heavy Debris and “Clean” Loads?

If you are doing a renovation, be careful with “mixed” vs “clean” loads. Mixing the following can drastically change your pricing:

Clean Fill: Dirt only
Clean Masonry: Concrete only
The Rule: If you fill a 20-yard dumpster with “clean” concrete, it’s recyclable. If you toss even one bag of household trash or wood on top, it becomes a “Mixed Load,” and you will be charged the higher tonnage rate.

Even a small amount of the wrong material inside a recycling-only dumpster can cause problems at the recycling facility.

First, recycling facilities are often not permitted by local or state DEC regulations to accept certain mixed materials. What may seem like a small amount in one dumpster can quickly add up to hundreds of cubic yards across multiple loads.

Second, contaminated loads require additional labor to manually separate materials from the recycling stream, and the facility then takes on the additional disposal costs of removing and transporting those non-recyclable items.

During renovations and demolition projects, it’s very common for materials to become mixed together as crews work quickly throughout the job. Separating heavy debris such as concrete, brick, dirt, asphalt, and metal from general construction waste can significantly reduce disposal costs and help avoid overweight charges.

For larger commercial cleanouts, warehouse tear-outs, or demolition projects, having a dedicated scrap metal dumpster on-site can be an especially cost-effective solution. Removing heavy metal debris from standard construction dumpsters lowers overall tonnage weight, and in many cases, metal-only containers are charged primarily by the haul fee rather than disposal weight.

Local Warning: In our coastal areas, beware of “Wet Debris.” If your debris is soaked from a storm or flood, it weighs significantly more, which can lead to unexpected overage charges at the scale.
