Old paint disposal: what are the types of paint?
It’s the big question after an exciting home renovation: how do you dispose of old tins of paint? Well, it all depends on the type of paint you’re dealing with. There are four categories of paint to consider when determining how to dispose of paint safely:
- Water-based paint, or emulsion
- Oil-based paint
- Aerosol cans
- Empty tins
How to dispose of emulsion paint (water-based)
Emulsion is water-based and so you might be tempted to get rid of excess paint by pouring it down the sink. While it’s okay to wash brushes in the sink, pouring large quantities down the drain is not recommended as this can cause problems in the piping and even can contaminate water supplies.
Water-based paint waste disposal techniques
Getting rid of paint such as acrylic is easier than oil-based paints. Water-based paint such as acrylic is not toxic and can be thrown away with the general waste provided it is fully dried out. Water-based paint can only be thrown away if it is solid, as liquid paint can cause problems contaminating other waste and its container, not to mention problems when your rubbish is removed by waste disposal people.
Leaving the lid off a tub of acrylic paint for a few days is enough to dry it out, but be sure to prick the paint before disposing of it to make sure there is no liquid at the centre. Alternatively, you could speed up the process by painting the remnants onto some card or adding in some sawdust.
How do you dispose of paint and paint cans that are oil-based?
If you’re working on a home project, you can arrange a domestic hazardous waste collection for the oil-based paint tin disposal. It’s also important to know that, if you’ve hired professionals to work on a home decoration job, the materials being used are still your responsibility as the homeowner. Because of this, you should make sure that the removal of waste materials is included in the quote provided to you for the work.
For larger commercial projects, where a high number of paint tins need to be collected and recycled, paint disposal companies can help to responsibly remove used paint cans. Arrange a quote for commercial hazardous waste collection to ensure your waste paint materials are dealt with properly.
How do I get rid of old paint cans such as spray paint?
How to dispose of old paint sprays like aerosol paint cans is quite straightforward. Simply ensure the can is fully empty by spraying it until no more paint comes out, then put them into your metal can recycling bin.
How to dispose of empty paint cans
The problem that makes disposing of paint difficult is that it is a liquid. This makes disposal messy and complicated. Empty paint tins are not so much of a problem but you should check if the paint was hazardous first, if so the empty paint cans need to be collected via hazardous waste disposal.
Can I throw away paint cans in the trash?
You cannot throw paint tins in the general waste, even if they are empty. Exactly how to dispose of paint cans depends on the paint left inside the tin. Even if the tins have been washed out they will still be classed as hazardous waste. This is because the paint, dried or not, is a harmful substance, and any trace of it miss when cleaning a tin could have a negative impact on the environment.
Where to take used paint cans that are empty
Whether the paint was water-based or oil-based, paint cans need to be recycled. Many paints are classed as hazardous waste, so properly disposing of used paint tins needs to be done with the help of a qualified professional. This means you’ll need to arrange a special hazardous waste collection, or otherwise take empty paint cans to a recycling centre that can deal with hazardous waste and knows how to dispose of paint tins.

- Recycling paint into other types of coatings
