Xylinum is a research project that poses the question: what could future materials and production processes be like? The title Xylinum is the name of a bacterium which produces an artificial cellulose material. This bacterium counsumes sugar and builds a cellulose fibre structure around any given form. Since the process takes place in a nutrition liquid, the wet material can be dryed later on, resulting in a durable and 100 % biodegradable material. The properties of this material can be adjusted by changing the genetic code of the organisms. In collaboration with the company Jenpolymers, a technique was developed to create a “skin” around a wooden stool frame, forming the coating and seating surface.
