Turning CO2 into Plastic: Caltech Develops Breakthrough Technology

Caltech researchers have developed a groundbreaking two-step system that uses electricity from sustainable sources to convert atmospheric carbon dioxide into useful plastics. The system first electrochemically transforms CO2 into ethylene and carbon monoxide, then feeds these gases into a second catalytic loop to produce polyketones, strong and heat-resistant plastics. This breakthrough offers a more environmentally friendly and sustainable path for plastic production, reducing reliance on fossil fuels. While still in the lab stage, the system's high-concentration output (11% ethylene and 14% carbon monoxide) and tolerance for impurities show immense potential.
