Inadequate disposal of antifreeze has the potential to cause significant environmental damage. If poured into drains or onto the ground, it may pollute water sources, endanger wildlife, and present a risk to pets and children, given its sweet taste.

Safely extract the antifreeze from your vehicle into a clean, leak-proof container. Always use protective gloves and eyewear to avoid accidental skin or eye contact.

Keep the sealed container in a cool, dry place, away from the reach of children and pets, until you are prepared to dispose of it.

Step 4: Locate a Nearby Recycling Center

Check online resources or contact your local government's waste management department to find recycling centers or hazardous waste facilities that accept used antifreeze.

Step 5: Transport the Antifreeze with Care

When ready to dispose of the antifreeze, transport the securely sealed container to the recycling center. Ensure it is stably placed in your vehicle to prevent spills during transit.

Upon reaching the recycling center, follow their specific instructions for disposing of the antifreeze. They may have designated areas or specific protocols for handling hazardous materials.
