Carbyon is developing a separation machine to extract CO₂ from the air. Ultimately, they want to deploy thousands of such machines. ’Our business is successful when we are carbon negative.’

In a small room on the High Tech Campus in Eindhoven stands a prototype of a separation machine. The machine has one inlet and two outlets. It sucks in air from the outside, and the two outgoing streams are different in one very important respect: the concentration of carbon dioxide.
