F.A.Q. Antifreeze

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.

Hazards

  • Toxic to small children and may be deadly to animals attracted by its sweet taste.
  • Spent antifreeze may contain metals from the engine (lead, zinc, copper).
  • Can disturb the biological action of sewage treatment and septic systems.
     

Handling

  • Collect and store spent antifreeze in sealed, labeled, plastic or metal container, away from heat sources, children and pets.
  • Never store in a beverage container; original container is best.
  • Clean up spills with absorbent (kitty litter, shredded newspaper, vermiculite, rags, etc.); bag waste materials and discard in the trash. Flush soiled area with water.
  • Do not mix with oil.
  • Do not dispose down the drain or in storm drains.
