Paints are made up of a combination of resins, pigments, solvents and additives. If you wash brushes or paint tins in a driveway or roadside gutter, the untreated waste can end up in our waterways via the storm-water system.
Environment Canterbury has spoken with local painters and is working with paint manufacturers and suppliers to help inform people about correct paint handling methods to ensure our local waterways are protected.
Below is some useful information for home handymen and trade workers.
The best was to avoid paint waste is to just buy what you need. Work out exactly the amount of paint you require for a job and then only buy that amount. Your paint retailer can help you do this if you know the surface area you need to cover.
Use leftover paint for touch-ups or apply another coat instead of disposing of it. If you are giving it away, make sure it is in the original container with the label intact.
Small amounts can be left to dry by removing the lid in an area away from children or animals. When the paint is completely dry, the paint and container can then be disposed of in your general rubbish.
Large amounts of leftover or unwanted paint should be taken to a ‘household hazardous waste drop-off’ facility or a privately operated scheme such as the Resene PaintWise facility.
Both Dulux and Resene offer a paint take back scheme where you can drop off your unwanted pain and know that it will be taken care of correctly.

If you are paid to paint, your waste is classified as “trade waste” and you should be considering a commercial system to suit your needs:
