There are several methods used for antifreeze recycling including filtration, distillation, reverse osmosis, and ion exchange.
How is used antifreeze recycled?
All waste antifreeze recycling methods involve two steps: 1) remov ing contaminants either by filtration, distillation, reverse osmosis, or ion exchange and 2) restoring critical antifreeze properties with additives.
Is antifreeze a recyclable waste?
Remember that only pure, used antifreeze can be recycled; antifreeze with traces of gas or oil must be disposed of at a hazardous waste facility.
How do you dispose of antifreeze?
When refilling your engine coolant, do not recycle the empty bottle. Traces of antifreeze in recycling facilities may cause cross contamination. Also, rinsing the container may lead to antifreeze ending up in waterways. The safest option is to dispose of your antifreeze container in your regular rubbish bin.
What happens recycled coolant?
Recycling Antifreeze and its Benefits
In California, it is illegal to dispose of antifreeze in the trash, ground, or storm drains. … Recycling antifreeze conserves the earth’s limited natural resources by reclaiming glycol.
What is antifreeze recycling?
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.
What type of waste is antifreeze?
First, antifreeze would be considered hazardous waste if it is mixed with a hazardous waste (such as gasoline).

Is antifreeze hazardous waste?
Many cleaning and maintenance products are considered hazardous waste such as antifreeze, lead-acid batteries, used oil and oil filters, oil/fuel saturated absorbents, solvents, paints, zincs, varnishes and cleaning products.
What are the 3 main properties of coolant?
low viscosity and density; chemical neutrality to construction materials; chemical resistance and harmless; low cost and availability.
Does antifreeze breakdown in the environment?
Potential Environmental Impacts: Antifreeze can pollute groundwater, surface water and drinking water supplies if dumped, spilled or leaked, and is harmful to marine and aquatic life. While in an engine, antifreeze can become contaminated with lead or fuel to the point where it must be managed as a hazardous waste.
Is antifreeze biodegradable?
Both propylene glycol and ethylene glycol are biodegradable and will soon break down into carbon dioxide and water.
Does antifreeze expire?
A sealed bottle of antifreeze has an indefinite shelf life. Once opened, it will keep for years if stored in the original container. Antifreeze – coolant that has not been mixed with water – tends to last even longer than pre-mixed engine coolant, though both last for years.
Does AutoZone recycle antifreeze?
Most of the AutoZone stores will accept transmission fluid, gear oil, motor oil, and automotive oil. They are also dealers in antifreeze and brake fluids. … At AutoZone, they will provide the recycling of all these fluids, all aimed at helping take care of your car and the environment.
