Discard paint residue
On this page we answer all questions about disposing of paint residue. How do you do this in a safe and responsible way? And what is and is not allowed? For example, can it go down the sink or in the residual waste container? In most cases, paint residues fall under chemical and hazardous waste. This is also called KGA or KCA.
Due to the harmful chemicals and solvents that many types of paint contain, rules and regulations have been drawn up by the Dutch government. This is how we ensure that together paint waste and processing takes place with the least possible impact on people, animals and the environment.
What to do with leftover paint?
You have painted your walls or window frames or hired a painter to do so. The job is done, but what can you do with the leftover paint? It can of course be useful to keep this in a safe place. You can then use it later to touch up any damaged paintwork. Paint residues can be stored in a tightly closed can or bucket, out of direct sunlight and at a cool temperature.
Are you not planning to use the remains of paint or is it very old paint? Then it is good to know that paint waste falls under small chemical waste. As a private individual, you can hand it in at the recycling center of your municipality. In some places this is called the waste depot, dump or waste collection station. Special KCA containers, KGA boxes or chemo carts are available at these municipal yards hand in old paint.
How to dispose of paint water?
Paint water contains harmful substances. So it is best to rinse used brushes and rollers in a bucket or empty paint can. You should not throw paint water down the sink or down the toilet. It then ends up in the sewage water. In addition, paint residues and pigments can become stuck in your pipes and sewer pipes, causing unpleasant consequences such as blockages. You can bring water with paint residue to your municipality in a closed bucket or can.
Can you flush paint down the sink?
No, it is very harmful to flush paint down the sink. It contains chemicals that are very harmful and should not end up in the sewer. Moreover, it is also very unwise to do so, because chemicals are corrosive substances that can destroy your pipes. Paint residues can also accumulate in your sewer pipes, resulting in blockages or leaks. So always take old paint to the recycling center.
Can turpentine go down the sink?
No, turpentine is not allowed down the sink. The same applies to other solvents, such as thinner. These are corrosive and also very toxic substances that should not end up in the sewer. They are difficult to filter by the water board. It is therefore prohibited to rinse turpentine residues through the sink. Moreover, it is not a smart thing to do, because you can seriously damage your pipes.
Where to throw away paint brushes?
You can throw away used paint brushes in special KCA containers at your municipality. Private individuals can often go to the recycling center 6 days a week to hand in old brushes, wall paint rollers and paint cans for free. In this way you contribute to a better environment.
Can paint be thrown in residual waste?
Paint falls under small chemical waste, also known as small hazardous waste (KCA or KCA). In most cases, this means that it should not be thrown away with residual waste. Almost all types of paint contain chemical, toxic and environmental pollutants. It must therefore be separated from household waste so that it can be processed responsibly and safely.
Only 100% dried water-based paint or completely empty paint cans or paint buckets may be placed in the residual waste container.
How do you throw away old paint?
The rule of thumb is to throw away old paint in the special containers at the recycling center, waste point or waste collection station of your municipality. You can deposit it there for free in the chemo cart, KGA box or KCA container. Paint is chemical waste and contains toxic and environmental pollutants. It should therefore not be disposed of with residual waste, as this is bad for the environment.

Where do you put paint waste?
Paint waste must be taken to the municipal waste depot. This is free in most cases. Paint waste includes all paint (residues), such as stain, wall paint, lacquer and component paint. Both in liquid or solid/dry form, on a water/alkyd/acrylic basis or turpentine basis. Brushes, rollers, painting tools, thinner, turpentine and other solvents also fall under (chemical) paint waste. It is not allowed in residual waste or down the sink.
What to do with leftover wall paint?
Have you painted your walls and do you have leftover wall paint? It is useful to store these leftovers in a tightly closed can or bucket. Then you can use this in the future in case of damage. Make sure it is not in direct sunlight and cannot get too hot or cold. Usually a good place to keep it is in a basement or shed.
Do you want to throw away leftover wall paint? Then think about the environment and take it to your municipality's waste center. If it is water-based paint and has dried completely, it can be thrown in the residual waste. In all other cases it falls under the category of small chemical waste and must be handed in separately.
What do you do with empty paint cans?
It is best to throw away old or empty paint cans in the special chemical waste containers at the municipality. In principle, you can put a single empty paint pot in your residual waste container, but you can go to the recycling center to throw away larger quantities or (semi-)liquid paint residues. A small effort and much better for the environment!
