A team led by chemists at the University of Liège has developed a new polyurethane production technique using CO2 to create new types of easily recyclable plastics. The study, published in the Journal of the American Chemistry Society, could provide a solution for the development of truly sustainable plastics.
Commodity plastics have transformed global industry. Whether in construction, clothing, vehicles or food packaging, these plastics are everywhere in our daily lives, so much so that their global use has been estimated at around 460 million tons in 2019.
"This number is staggering, but not surprising, because plastics, also known as synthetic polymers, have met a large success thanks to their irreplaceable characteristics: they are light, cheap and incredibly versatile," explains Christophe Detrembleur, chemist at the Center for Education and Research on Macromolecules (CERM) of the University of Liège. "However, the fact that they are difficult to recycle, or even impossible to recycle in the case of thermosets, has serious consequences."
