Biomass plastics
BioethanolWe have succeeded in producing polylactic acid and polyethylene as wood-derived
biomass plastics, and will continue to establish mass synthesis methods and develop

applications. The knowledge of producing polyethylene from ethanol may also be applicableto the production of "Sustainable Aviation Fuel (SAF)," and we will examine the possibility ofproviding wood-derived ethanol as raw materials for SAF.

Cellulose nanofiber (CNF) is produced by nanofibrillation of pulp to a nanometer order (1nm= 0.000001mm). Taking advantages of its functions and features such as transparency,lightness, and durability, we will continue development of CNF for further practical use tomeet a wider range of needs, including construction sites, sports products, and cosmetics.

The Oji Group is promoting innovation based on the diverse core technologies
it has developed over 150 years of paper manufacturing and forestation sinceits founding, and is actively working on the following three themes as newmaterials derived from wood fiber.

Lactic acid

Suger solution

Ethanol

EnzymeRecoveryWith the super-aging society and growing interest in extending healthy life expectancy, there
is a need for new and different form of medicine and healthcare. The Oji Group has developed
a technology to produce active pharmaceutical ingredients from wood. We are going beyond
our traditional businesses to enter the medical and healthcare field and meet new needs forhuman and animal medicine and healthcare.

CNF has great potential as a structural member of composite materials, and its role as areinforcement material will be a focus in the future.

・Both natural rubber and CNF are natural materials
・New materials utilizing the characteristics of CNF

Composites made from natural rubber and cellulose are expected
to replace existing materials with fossil fuel-derived fillers.

Oji's proprietary technology is puriﬁcation of hemicellulose, one of the major components of wood, to a high degree of purity for pharmaceutical use.
