Summary
More than 6 million metric tons of polypropylene (PP) is produced annually in the U.S. It is the second most produced plastic in the U.S. Less than 1% of this PP is recycled because common recycling methods are inefficient and often produce low-quality material. Instead of recycling PP, a special chemical process with catalysts can break down PP into useful products, turning plastic waste into valuable materials. However, when PP melts, it becomes thick and sticky, which makes it hard to heat and mix evenly during processing. This CAREER project will study how carbon dioxide at certain tempe
