| Outline of Final Research Achievements |
This work investigated the production of eco-refinery pulp contained cellulose nanofiber (CNF) from moso bamboo using high-temperature and high-pressure steam treatment combined with the milling treatment. This pretreatment method can be considered as an environmentally friendly method because the treated product contains only wood-derived components and water that generally do not lead to significant corrosion problems and formation of neutralization sludge. The specific tensile strengths of CNF obtained in this work were almost the same values as that of a commercial CNF. Furthermore, an eco-refinery pulp was made of holocellulose and CNF those were obtained from moso bamboo by this pretreatment method and its mechanical strength was evaluated. By changing the steam treatment conditions, it is possible to produce eco-refinery pulp of various specific tensile strengths adapted to the application and purpose.
