PureCycle Technologies and Mitsui & Co. Ltd. announced a signed heads of agreement (HOA) to develop and operate a polypropylene (PP) recycling plant in Japan. In September of 2021, the two sides announced a signed memorandum of understanding.

The two sides are targeting completion of a plant in 2026. The first plant is designed to transform PP waste into an ultra-pure recycled (UPR) resin and expected to have an annual capacity of 59,000 metric tons (130 million pounds). PureCycle uses a patented technology that can remove virtually all contaminants, colors and odors from polypropylene plastic waste (designated as No.5 plastic) and transform it into an ultra-pure plastic resin that can be used multiple times.
