Oji Holdings starts operation of pilot Cellulose Nano-Fiber facility in Japan

Oji Holdings Corporation (Oji) announced start of pilot facility for Cellulose Nano-Fiber (CNF) production in January 2017. According to the announcement, in December 2016 the company completed installation of the equipment with 40ktpa production capacity at Oji Paper’s Tomioka Mill, located in Anan city, Tokushima prefecture of Japan.

At the same time, Oji is proceeding to demonstrate that chemical treatment process involving phosphate esterification is the most efficient and produce high quality CNF in terms of high transparency, high viscosity and thixotropic property.

OJI installs a new manufacturing demonstration facility for cellulose nanofibers

OJI Holdings Corporation (OJI) announced  installation of a new manufacturing demonstration facility for cellulose nanofibers (hereafter, CNF), which applies a phosphate esterification chemical treatment method.

After evaluation of a variety of chemical processes which could potentially reduce the energy requirements of the refining process OJI determined that newly developed chemical treatment process involving phosphate esterification is the most feasible technology at the present time to achieve practical implementation. Therefore, OJI has decided to install a manufacturing demonstration facility to further inspect this production process.

With the introduction of the demonstration facility, OJI expects not only inspect the energy reducing effects of this production process, but broaden array of samples to be provided to users at the implementation stage. This will also expedite the initiative towards commercialization. The company states the following merits of the original phosphate esterification process:

  1. This technology enables us to produce CNF with high quality (ultra-high transparency, ultra-high viscosity).
  2. It will also provide the means to manufacture by using exclusively safe chemicals (phosphate, etc.) found in common products such as cosmetics.
  3. We expect strong electrostatic resistance between individual CNF which may substantially reduce the energy required in the manufacturing process.
