MATERIAL INFORMATION

Home >> Waste Directory "Yellow book" >> Material List >> Material Information

 
 
Service Type: Business
Material: Antifreeze
Proper Disposal: Antifreeze that is not recycled must be disposed of as a hazardous waste.
Recycle: • Recycle antifreeze on site with your own recycling equipment.

• Recycle antifreeze with a vendor (see the vendor list below).

• Always separate ethylene glycol antifreeze from propylene glycol antifreeze for successful recycling.

• Eligible small quantity generator businesses can bring small amounts of antifreeze to one of the collection facilities listed below. For more information go to the Small Business Hazardous Waste Disposal link.


The Department of Ecology exempts recycled spent ethylene glycol antifreeze from being counted in your shop's monthly hazardous waste totals if certain best management practices are followed.
For more information, go to the Antifreeze link below or call Ecology at 425-649-7000.
Potential Hazards: • Antifreeze is toxic hazardous waste if it contains ten percent or more of ethylene glycol.

• Waste antifreeze (whether ethylene glycol or propylene glycol) can also contain toxic contaminants like lead and benzene.
Safer Alternatives: Antifreeze solutions made with propylene glycol are less toxic than those made with ethylene glycol, but they can also become hazardous after use.
