Outline of Final Research Achievements |
Paper sludge (PS) is one of the typical waste materials in the papermaking industry. The reuse of PS was difficult due to the existence of various minerals and damages in the pulps. Therefore, we extracted cellulose nanofiber from the PS by using chemical and physical treatments. The extracted cellulose nanofibre was combined with biodegradable resin to make green composites, and then the mechanical properties were examined. We found that the green composites obtained had tensile strength of 115 MPa and Young's modulus of 6.8 GPa. It is suggested that these high properties were derived from fiber reinforcement from cellulose nanofiber extracted and refinement of mineral particles by ultra-sonication during the extraction process.
