Exploring acid hydrolysis conditions and extended mechanical processing for producing cellulose nanocrystal and nanofibrils from pineapple leaf fibers.

This study investigates the potential of pineapple leaf fiber (PALF), as a renewable source, to produce cellulose nanofibrils (CNF) and cellulose nanocrystals (CNC), addressing a gap in the literature regarding optimal conditions for CNC extraction from PALF. Chemical analysis revealed a high α-cellulose content (78.14 %), making PALF suitable for nanocellulose production.
