RE‑DAR
Waste that tells its origin.
A ceramic paint made 100% from wastewater sludge.
The water we drink leaves a sludge behind. Here it becomes colour.
Every treatment plant produces tonnes of sludge a year. RE‑DAR treats it as a raw material: it is dried, ground, dosed and fired until it vitrifies.
Tone and texture change with the metals in each city’s water. What goes down the drain comes back into view, and it can be measured.
Treatment-plant sludge in the mix.
Each batch changes colour with the metals in the water.
An earthy finish for exhibition pieces and wall finishes.
From treatment plant to glaze
Three treatment plants around Barcelona, three different sludges. Dry, grind, dose and fire until you find the temperature at which each waste vitrifies.
What we throw away keeps a memory too.
Let us design something that stays.
