CLV is part of Swegon’s RE:3 concept based on the key principles of circularity, and which consists of RE:duce, RE:use and RE:vitalise. CLV is made with sustainable sheet metal called RRP, where RRP stands for “recycled and renewably produced”. The steel has a recycled steel content of at least 75 per cent. In addition, the manufacturin process uses electric arc furnaces that run on 100 per cent renewable energy.
