Alkaline thermal process generates hydrogen fuel from mixed plastic waste

A team of researchers from the Ewha Women’s University and the University of California at Los Angeles have taken a step toward addressing one of main challenges in plastics recycling — economically processing mixed plastics streams without the need for presorting. They developed a method, known as alkaline thermal treatment (ATT), that can directly convert mixed polymers, including polyethylene terephthalate (PET), polyethylene (PE) and polypropylene (PP), into hydrogen at temperatures significantly lower than conventional gasification and at atmospheric pressure.
