Colruyt has modernized 76 Okay stores from the beginning of 2018 to now. The retailer also took care of the facades with the new coat of paint. A total of 10,000 square meters are covered with the air-purifying paint, which, according to the maker, can neutralize the emissions of 1 million kilometers annually with a modern diesel engine.
“The rain washes the facade clean again”
The catalyst in the air-purifying paint is modified titanium dioxide, a pigment for white paint. It reacts with sunlight and converts nitrogen oxides with the help of oxygen into nitrates and ozone into oxygen. “The rain then washes the facade clean again,” says Alexander Rickert of producer Sto. "As long as there is light on the facade, operation is guaranteed."
Future plans for Bioplanet stores
The retailer did not disclose the size of the investment for Colruyt. The new layer was not applied to the other 61 Okay stores because they were still too recent to renovate, says Ivo Van Zandweghe, responsible for sustainable infrastructure of the Colruyt Group. "There are already plans for the future to do the same at some thirty Bioplanet stores."
