Biocement is made using bacteria to bind recycled bricks together with calcium carbonate. The process doesn’t require firing or emit CO2. Using biofabrication and 3D printing, innovative forms of the material can be created. During the project, the key functional and aesthetic potential of biocement was investigated and used to design a piece of seating furniture. The chair, consisting of three individually manufactured profiles, was created to make research more accessible through design.
