Indus was designed and created at the Bartlett School of Architecture as a modular system of algae constructed tiles. Each tile is made by pressing clay into a fan-shaped mould which is then filled with micro-algae. The tiles are then suspended within a “biological scaffold” of seaweed-derived hydrogel to keep the algae alive.
Once erected and assembled on a wall, water is poured into the system through inlets at the top. It trickles through the tile channels and is collected at the bottom. As water moves over the channels, the water is subject to a process called bioremediation, in which microorganisms such as algae or fungi are used to consume and break down toxins in the environment.
