Since 2017, the process is used by a large paper company in Japan to manufacture CNF in the form of dispersed nanofibers with uniform fiber width of 3 to 4 nm.26 The company starts from bleached wood pulp at two different paper mills, and supplies the “Cellenpia” product series to different industrial customers producing CNF-reinforced tires, paper barrier cups for beverages, personal care, hygiene, and cosmetic products.26 In 2019, the same company successfully developed a CNF-reinforced composite subsequently used to produce a car whose weight was about 10% lower than a conventional car made in steel.27
