Alexandre Marronoz’s new urban outdoor seating designs, as the designer says, “take the concept of “green” furniture a step further.” The free form designs are inspired by nature, interpreted as large stones, tree trunks, or logs “for sitting, refecting or simply breathing the fresh air.”  The pieces, made from TX Active cement, double as urban seating and sculpture. TX Active contains a photocatalyser that speeds up the natural oxidation process of pollutants in the presence of natural or artificial light, making it more environmentally-friendly as it transforms the pollutants into compounds such as water, nitrates, or carbon dioxide.
