where can i recycle antifreeze
Most recycled antifreeze is put back to use treatment as antifreeze. Automotive shops can recycle it on site using specialized machinery. The machines remove the heavy metals and any oil that has made its way into the liquid, and then add chemicals to keep the ethylene glycol from breaking down.owever, it is important to recycle antifreeze no matter the contents. As the liquid passes through the engine block, it picks up heavy metals such as lead and cadmium. This adds to antifreezeâs toxicity and is another reason it is treated as hazardous waste by most states.
