The MCMUA operates one of NJ's most comprehensive household hazardous waste (HHW) programs. This F.A.Q. page and information on hazardous materials is intended as a guide about HHW materials as well as the MCMUA's HHW program. This information is a general guide and does not constitute official rule, regulation or law.
Hazardous Waste Materials
- Appliances (CFCs)
- Art & Crafts
- Batteries (Auto & Boat)
- Batteries, Household (dry cell)
- Cell Phones
- Compressed Gas Cylinders
- Driveway Sealer
- Fire Extinguishers
- Medical Waste
- Motor Oil & Filters
- Muriatic Acid (HCl)
- Paints & Stains
- Photo Chemicals
- Pool Chemicals
- Rock Salt
- Smoke Detectors
- Wood with Lead Paint
- Thinners and solvents contain volatile organic compounds (VOCs)
- Thinners and solvents can be absorbed through the skin.
- Thinners and solvents are flammable.
Some solvents are carcinogenic.
- Keep thinners and solvents in closed and labeled glass or metal containers. Some plastic containers may deteriorate in contact with solvent.
- Store thinners and solvents away from sources of sparks or heat.
Do NOT put leftover product in the trash or down the drain.
- If product is unused, try to give it away to someone else who can use it.
- If the product cannot be given away for reuse, and the municipal paint collection program accepts it, take it there.
- Solvents mixed with paint may be reused. First, let solids settle out and pour off liquids for future use as a solvent. Label container clearly.
- The solids may be disposed of wet at an HHW collection. Alternatively the solids may be dried out by adding absorbents such as kitty litter or vermiculite, in a well ventilated area, away from ignition sources such as appliances with a motor or pilot light and out of reach of children and pets. Dried solids can be disposed of in the trash.
- Small amounts of used or new paint thinner can be added into oil-based paint. Add to same color paint as that used with the thinner.
If the thinner or solvent cannot be reused through the above options, save for the next HHW collection day or take to a commercial hazardous waste facility.
