Overview

Comparative study shows improved cellulose nanocrystal production in non-food biomass, indicating enhanced nanomaterial sustainability.

Key Points

  • This study aims to evaluate the production of cellulose nanocrystals from sea mango fibre waste using different hydrolysis methods.
  • Utilized sulfuric acid hydrolysis for cellulose extraction.
  • Optimized conventional hydrolysis parameters via Taguchi experimental design.
  • Applied ultrasound-assisted processing to enhance CNC production.
  • Conducted kinetic analysis using Saeman first-order and two-fraction models.
  • Characterized CNC properties through structural and thermogravimetric analysis.
  • Achieved a maximum CNC recovery of 72.09% under optimal conventional hydrolysis conditions.
  • Ultrasound-assisted processing reduced reaction time from 60 min to 30 min.
  • Increased apparent rate constant for CNC formation to 0.1213 min−1 with ultrasound.
  • Produced CNCs with 82.23% crystallinity and narrower particle size distributions compared to conventional methods.
  • Confirmed the presence of sulfate ester groups on CNC surfaces via characterization.
