Antifreeze or ethylene glycol is the 30th highest volume chemical produced in the United States. At UWM, ethylene glycol is in the top 10 highest volume chemicals used.
Recycling is a favored option over disposal for ethylene glycol.
However, the Milwaukee Metropolitan Sewerage District, the authority which regulates our sewer discharges, prohibits recyclable amounts of ethylene glycol from being sewer disposed. Recycling The UWM fleet garage has a recycling unit capable of cleaning, analyzing and reconstituting spent ethylene glycol into usable antifreeze. The process uses a closed loop system to clean, reconstitute and replace the antifreeze from a motor vehicle back into that same vehicle. Batch loads can also be processed. If the anti-freeze is contaminated with other known hazardous constituents, contact Hazardous Waste Management and we'll arrange for pickup and disposal of your waste.
