Antifreeze should be identified by its formulation and contamination, not by colour alone. Used coolant can contain oil, corrosion products and cleaning chemicals that were not present in the original product. We take those changes into account before arranging collection.
Antifreeze Disposal
Antifreeze disposal for used coolant and unwanted stock held in workshop containers or larger vessels.

Coolant composition
Product formulation and contamination determine classification; colour does not.
Separation of workshop fluids
Mixing coolant with oil or other liquids can change hazards and limit treatment options.
Used coolant and workshop contamination
Different glycol and additive systems can produce different wastes. Mixing antifreeze with waste oil, brake fluid or other workshop liquids can change the hazards and make treatment or recovery more difficult. Keeping fluids separately identified preserves useful information about each stream.

Bulk and packaged coolant
A bulk vessel needs suitable transfer access, while small bottles and drums need secure closures and packaging appropriate to the liquid. Contaminated absorbents and empty containers are separate materials and should be identified if they are to be removed at the same time.
Changes in coolant products
A workshop may switch coolant products while continuing to use the same waste container. That can change the composition of the waste even if its colour looks similar. Previous classification should therefore be reconsidered when the product or process changes materially.
Antifreeze Disposal: common questions
Is antifreeze always hazardous waste?
The actual formulation and contamination determine classification. Different coolant products and used fluids can differ.
Can antifreeze be added to a waste oil drum?
Keeping the fluids separate preserves their identity and avoids changing hazards or restricting recovery.
Does coolant colour identify its waste code?
No. Colour is not a reliable basis for classification. The source and composition of the waste are what matter.
Can spilled antifreeze absorbents need separate disposal?
Yes. Their contamination and material need assessment and explicit inclusion.
Does dilution automatically make coolant non-hazardous?
No. Classification depends on the actual composition and hazardous properties of the waste.
