Project PhycoForm embraces the circular economy framework by creating a biodegradable range of architectural products derived from the residues of harvested Tasmanian seaweed and other locally available waste resources. Designed for a niche clientele who are climate conscious, this bespoke material was created as an alternative to the existing unsustainable construction materials in the market. My material exploration investigates the unique properties of alginate present in brown seaweed and how this can be utilized to make more resilient and fire-retardant building materials.
