Despite digitisation, the demand for printing ink is rising. Ink is one of the most expensive liquid commodities in the world. The most expensive ingredient for ink is pigment. Coffee on the other hand - has become the most consumed beverage in the world. Every day we produce coffee waste that is equal in weight to 3 Eiffel towers.
In a response to this waste stream, our team develops a method to create pigments out of this coffee waste. If all of the global coffee waste were to be processed into pigment, it would provide 50% of the global pigment market.
