Carlo Ratti Associati designs "world's first fully compostable marker"
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) ? a polymer that is used to produce biodegradable plastic ? and lignin.
The replaceable cartridge would be filled with a non-toxic, water-based ink made from edible ingredients and composted after it is used.
The bioplastic pen outer will be fully compostable, made from the same materials as the cartridge, while the wood and aluminium barrels aren't compostable but are designed to last a long time. Carlo Ratti Associati has designed a concept for the "world's first" compostable marker pen
"Upon learning that over 35 billion markers are sent to the landfills every year, we began to work on a solution in line with the concept of circular economy," said the CRA design team.
"As we arrived at the innovative concept to create a cartridge that can be separated from the barrel, we tested a large amount of organic fibres in order to produce the biodegradable cartridge with the optimal performance."
