Together with the research institute RISE, we have investigated how to sustainably dispose of used painting tools. The survey showed us that 55%* of people wash their roller directly in the sink, risking that plastics, metals and other hazardous substances from paint end up directly in the drains. These types of dyes cannot be cleaned by wastewater treatment plants, which means that hazardous substances are released directly into the sea, where they have a harmful effect on the environment. Our research shows that the most sustainable way is to dispose of the roller after use. Below we describe how to proceed.

1. Scrape off the paint
Use a roller scraper to get as much paint out of the roller as possible. By using a roller scraper, you can save up to 64% of the paint contained in the roller*, which is equivalent to about 1-2 m² of painting, depending on which roller you use. Paint you can reuse for other projects instead of throwing out!

2. Are you going to keep painting? Use plastic wrap!
Should you continue to use the roller with the same colour? Make sure to wrap your roller tightly with plastic wrap or a plastic bag to keep it moist. Then you can use it again the next day. Once you’ve finished your roller, lay it on some paper towels or newspaper and let it dry completely.
When you have finished painting with your roller and it has dried completely, throw it in the household waste.
