How to Properly Dispose of Old Antifreeze in Your City

Why Antifreeze Disposal Matters

Antifreeze contains ethylene glycol or propylene glycol, toxic chemicals that poison water supplies and harm ecosystems. Even small amounts of antifreeze contaminate groundwater and surface water. Canada has strict environmental regulations governing antifreeze disposal. Proper disposal protects your community's water and environment.

The Toxicity of Antifreeze

Ethylene glycol antifreeze is highly toxic to humans and animals. Small quantities can cause serious illness or death. Antifreeze has a sweet taste that attracts children and pets, making accidental poisoning possible. Propylene glycol is less toxic but still harmful. Never leave antifreeze accessible or dispose of it improperly.

Canadian Environmental Regulations

Canada classifies antifreeze as a hazardous waste. Federal and provincial regulations prohibit pouring antifreeze into municipal sewers, storm drains, or soil. Violating these regulations can result in fines up to several thousand dollars. Businesses and individuals must comply with proper disposal requirements.

Municipal Hazardous Waste Collection

Most Canadian cities operate hazardous waste collection programs. Contact your municipality to find designated collection dates and locations. Many cities accept antifreeze at designated drop-off centers year-round. Some offer curbside pickup for hazardous materials. Services are typically free or low-cost for residential generators.

Automotive Repair Shop Disposal

Local automotive repair shops collect and properly dispose of antifreeze. When you have your radiator flushed at a local shop, they handle antifreeze disposal professionally. Many shops will accept antifreeze from DIY customers for a small fee. This is often the most convenient option.

Retailer Take-Back Programs

Many automotive retailers accept used antifreeze for free when you purchase new antifreeze. Some retailers have take-back programs specifically for hazardous materials. Check with local retailers for their specific policies. This is often the easiest option if you're purchasing new coolant.

Storing Old Antifreeze Safely

Store used antifreeze in sealed, labeled containers. Keep it away from children and pets. Store it away from food and water sources. Keep it in a cool location away from direct sunlight. Store antifreeze only temporarily while arranging proper disposal. Never store large quantities for extended periods.

Finding Your Local Disposal Options

Search online for your city plus hazardous waste disposal. Check your municipality's website for collection programs. Call your local environmental department for guidance. Ask your local repair shop where they recommend disposing of antifreeze. Most communities have multiple convenient options.

The Cost of Proper Disposal

Proper antifreeze disposal is free or very low-cost at most locations. Municipal collection is typically free. Repair shops may charge $5-$15 for disposal. This minimal cost is far less than potential environmental cleanup expenses or legal fines for improper disposal.

Why Not to Pour Antifreeze Down the Drain

Pouring antifreeze down the drain violates environmental laws and contaminates water. Municipal water treatment systems don't remove antifreeze. It enters groundwater and surface water, poisoning aquatic life and potentially human water supplies. Never pour antifreeze into drains, storm sewers, or soil.
