MUD 4-C7
Output
Material sample tile is made with residues from wastewater treatments from the ceramic production and leftover clay.
This tile is part of the MUD MATTERS project for Porto Design Biennale 2023.
Starting with the raw material "mud" various recipes were developed involving different percentages of sewage sludge, ranging from 0% to 100% reuse.
