The water used for production is treated and reused, and the heat from the cooking ovens is recovered and returned. In addition, materials such as clay chips that are produced during ceramic manufacturing are reintroduced into the manufacturing process. ASA Selection's production partner also applies this sustainable strategy to enamel: the enamel that overflows during the process is thus recovered and then filtered and can then be used for the new Re:glaze series. The result is recycled clay sandstone, combined with incomparable white.
