In 2018, 61.8 million metric tons of plastic waste was produced in the European Union with only 9.4 million metric ton recycled. This constitutes a huge amount of plastic waste, which rapidly needs to be addressed. One solution is to turn to magnetic density separation, which can separate plastic materials using magnetic fields, but this technique is not always effective. Rik Dellaert studied flows of plastic particle mixtures in wind tunnels to assess the effect of turbulence on the separation process. He’ll defend his Ph.D. thesis on November 26th at the department of Applied Physics.
