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:
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.
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.
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 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.
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.
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.
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.
How to dispose of used paint isn’t as straightforward as throwing it out with your general waste. Let’s look at what to do with unused paint that doesn’t involve waste or recycling.
Your excess paint could come in handy to someone working on a project of their own. Before deciding how to get rid of paint consider asking friends, family and neighbours if they could use it.
You could go further and put a post on social media with some pictures of the paint shade and how you used it. Someone might be inspired and would be happy to get some free paint. Independent workmen might also have a need for paint, so this is a good way to get on their radar.
Casting the net ever wider, there are community projects in the UK that are always on the lookout for leftover paint. RePaint is an organisation that can connect you with groups in your area looking for unwanted paint.
Taking paint and paint cans to your local tip is one of the best ways to dispose of unused paint. Just be sure to check the facility can accept hazardous waste beforehand.
As a skip hire company we’re often asked ‘can you put old paint in a skip?’ Due to the fact that paint is classed as a type of hazardous waste, it cannot be put into a skip. Paint that is dry and empty paint cans cannot be put into a skip either.
As a rule of thumb, only general household waste can go into a skip
Recycling paint tins is the correct way of disposing of paint. All liquids are banned from landfill, including paint. However, you cannot recycle old paint cans in your normal household recycling bins either if the paint is oil-based. UK laws dictate that as hazardous waste, paint cans should be handed over to a registered hazardous waste handler to deal with.
The recycling rate in the UK continues to steadily grow. In 2017 we had achieved a 45.7% recycling rate for household waste. Our recycling efforts are supported by recycling conscious waste collection companies, and recycling centres up and down the country. When you arrange a waste collection with a company like T W Services you can be sure that all waste materials will be recycled where possible, including paint recycling.
If you’re wondering where to recycle used paint cans yourself, many recycling centres have the capacity to deal with hazardous waste recycling. However, you’re likely to be charged for taking paint cans to a recycling centre and there may be a limit to the number of paint cans you can take along.
The process to recycle paint cans involves sorting the paint into different categories: water-based, oil-based, aerosols, and empty paint cans. Different uses can then be determined depending on the quality of the paint. Some uses are:
Several paint manufacturers like Dulux run schemes to support more sustainable household paint disposal. It’s a good idea to check with the manufacturer of your paint whether you can hand in old tins to be used.
Plastic paint cans are not yet as widely recyclable as metal ones. If the paint was oil-based you may need to arrange for the plastic containers to be collected by a hazardous waste collection service.
