Biocement is produced by stimulating thousands of bacteria to form solid structures: In presence of urea and calcium chloride, Sporosarcina pasteurii is connecting granulated building waste with calcium carbonate. In the production process, neither a firing process and thus a lot of energy is required nor CO2 is emitted. The combination of biofabrication and digital tools enables the material to be formed in a new way. The project investigates the key functional and aesthetic potentials of the new material. Serving as an object of knowledge, it has been translated into a seating furniture.
