Back to all initiatives

Facade specialist Sto has completed the first large-scale Belgian project with air-purifying exterior paint in collaboration with the Colruyt Group. No less than 10,000 square metres of facade surfaces of 76 OKay neighbourhood supermarkets in Flanders and Wallonia were provided with a layer of StoColor Photoscan. Thanks to an innovative technology, this paint purifies air pollution via nitrogen oxides from local traffic emissions. To go by German research, the project has the capacity to neutralize the emissions of approximately 1 million kilometres driven by cars.
