MUD 2-C6
Output
Material sample tile is made with mud-like sewage sludge - a residues from wastewater treatments from the ceramic production collected from ARCH Valadares and atomized stoneware GM by MOTA Ceramic Solutions.
Starting with the raw material "mud" various recipes were developed involving different percentages of sewage sludge, ranging from 0% to 100% reuse.
This tile is part of the MUD MATTERS project for Porto Design Biennale 2023.
MUD - sewage sludge - results from the entire process of transforming raw materials into clay of Vitreous China (Sanitary Porcelain), Gresanit (Fine Fire Clay), and HighCer, as well as in Glaze/Enamel, followed by the transformation into the final product (shaping, finishing, glazing, etc.). This mud also includes the cleaning of all production sections.
Raw Materials: Clays, Kaolins, Feldspars, Silica, Zirconium Silicate, wollastonite, Zinc Oxide, byproduct (recycling of our non-conforming product).
