Antifreeze

Antifreeze Recycling

Antifreeze combined with water creates a coolant for internal combustion engines. In addition to acting as a coolant, antifreeze also protects engines from freezing and corrosion. Antifreeze is commonly made from ethylene glycol or propylene glycol, which are toxic to humans and animals.  As coolant circulates through an engine, it may pick up heavy metals, causing the antifreeze to become hazardous. Due to its toxicity and potentially hazardous qualities, it is important to recycle or dispose of antifreeze properly.

While it is common to replace coolant every two years or 30,000 miles, Do-It-Yourselfers should consult their vehicle’s manual to determine how often it needs replacing. DIYers should never dump antifreeze on land, place it in the trash, or discharge it to a storm drain, ditch, stream, or septic system. 

If you are looking to dispose of or recycle antifreeze, some used oil collection centers accept it. To find a facility near you, visit our interactive map.

The State of Tennessee also offers Household Hazardous Waste collection events throughout the year where you can dispose your antifreeze. To find an HHW event near you, visit our HHW event page.
