Italian studio Carlo Ratti Associati (CRA) has designed a concept for a compostable marker pen comprising natural fibres and a water-based, edible ink that would break down within six months.
The Scribit Pen comprises a barrel made from a choice of either wood, bioplastic or anodised aluminium, which is designed for repeated use.
This holds a nib and cartridge made from natural fibres including sawdust, hemp fibres, polyhydroxybutyrate (PHB) ā a polymer that is used to produce biodegradable plastic ā and lignin.
