Featuring seven tile sizes, Pietra Jura is the first eco++ line from Coem. An eco++ designation means that the porcelain stoneware is fired at a temperature that is 100 C lower than conventional firing temperatures, which the company claims reduces CO2 emissions by 30%. Made from more than 30% post-consumer recycled content and 10% pre-consumer waste, the tiles weigh an average of 12% less than conventional tiles of an equal size and thickness, according to Coem. www.coem.it
