Antifreeze Do not pour unused or unwanted antifreeze into a storm sewer or down the drains in your home. Storm drains flow directly to streams and Lake Erie. Antifreeze is a serious health hazard to humans and animals if it is ingested. Antifreeze from a residence should be disposed via the Household Hazardous Waste Disposal Program. City service departments hold seasonal or year-round collections for residents. Are you a business? There are different rules for disposal of haz waste from a business, including antifreeze. Businesses must contract with a licensed company for proper disposal or recycling. See our Business Recycling Directory.
