Implication

Randomized trial demonstrates improved delignification and sugar yield in oil palm empty fruit bunches, suggesting an efficient biomass valorization method.

Key Points

This research aims to enhance the saccharification efficiency of oil palm empty fruit bunches (OPEFB) through microwave-assisted pretreatment.
Investigated microwave-assisted pretreatment using 1% H₂SO₄ and 1% NaOH under single-step and sequential schemes.
Utilized compositional analysis, SEM/FTIR/XRD characterization, and delignification kinetic modeling.
Conducted enzymatic hydrolysis to evaluate total reducing sugar (TRS) yield.
Achieved 71.52% delignification with 45.63% cellulose and 24.14% lignin in the solid residue.
Enzymatic hydrolysis produced 13.66 g/L total reducing sugar (TRS) with an 85.35% yield, a 4.2-fold increase over untreated OPEFB.
Delignification followed a third-order model with R² values above 0.984 at multiple temperatures.
