CO₂alescence is a homeware line of durable, stone-like pieces made for daily use. The material micro-sequesters CO₂ using mineral carbonation and microalgae, bound by pine resin and ambient-cured without kiln firing. This low-energy process reduces emissions, and the products can be repaired or remolded at the end of their long life, promoting a circular system. Each piece states the grams of CO₂ used in its making.
