Colruyt has modernized 76 Okay stores from early 2018 to now. The retailer also took care of the facades with a new coat of paint. In total, 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”
he catalyst in the air-purifying paint is modified titanium dioxide, a pigment for white paint. It reacts with sunlight and converts nitrogen oxides into nitrates with the help of oxygen, 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, the operation is guaranteed.”
Future plans at 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 too recent to be renovated, says Ivo Van Zandweghe, responsible for sustainable infrastructure at the Colruyt Group. “There are already future plans to do the same at about thirty Bioplanet stores.”
