Day 353 – Antifreeze lowers the freezing point of the water in your engine and prevents boiling in high temperatures. So, it is necessary for your car to use antifreeze throughout the year. There are two types of antifreeze, toxic and non-toxic. Antifreeze made from ethylene glycol is toxic. Antifreeze made from propylene glycol is non-toxic and has been approved by the Food and Drug Administration for safe human consumption in low doses.

Tips on Recycling Antifreeze:

1. If unopened, it will last indefinitely.
2. Once opened it should last up to eight years.
3. Some auto stores will accept antifreeze to have recycled. Check the Earth911 database for local recycling options. 
4. Take it to your local household hazardous waste (HHW) program.
5. Many HHW locations operate swap shops where you can pick-up free products. This is a great way to get more antifreeze.

“Most used antifreeze is recycled into new coolant by filtering out any metals or oil and adding new chemicals. So, you may be buying recycled antifreeze without even knowing it.” – Earth911
