Advanced Recycling Method for Polyethylene and Polypropylene Solid Wastes

Dr. Damien Guironnet from the University of Illinois has developed a chemical recycling method for upcycling propylene and isobutene solid wastes. This technique may be used to produce higher value feedstock materials (e.g., propylene and isobutene) from polyethylene and polypropylene with high selectivity. This process achieves high yield, in comparison with other chemical recycling techniques, through a combination of reactor design, catalyst selection, and process optimization.
