Model notes

  • Tensile model: 3.4·cellulose% + 2.1·crystallinity − 60 (MPa), calibrated against bast-type lignocellulosic fibre.
  • Nanocellulose side stream fixed at 22% of technical fibre via TEMPO oxidation route.
  • Remediation credit: 26 m³ of waterway cleared per tonne of wet biomass removed.
