Award winning designed Swiss pen. The casing of this writing instrument is made out of biobased, biodegradable and non-toxic biopolymers (PHA’s) which are sustainably generated through natural processes like biosynthesis. The same natural way microorganisms produce biopolymers, they also rapidly decompose them again- wherever they happen to be, even at sea. So what appears to be plastic was actually manufactured naturally by microorganisms. The paper used for the pen pouch was made from algae, which otherwise clog up fragile marine areas.
