“…However, these results cannot be compared because the processes were carried out without the prehydrolysis stage. The findings of Dewi et al [ 12 ] with nipa palm petioles cannot also be compared. This implies that the effect of prehydrolysis time on the NPF pulp yield and kappa number after cooking was first reported in this study.…”

“…Soda-SAQ cooking and TCF bleaching are considered environmentally friendly due to the sulfur-free process in the cooking and reduction in the halogenated organic compounds emissions during bleaching [ 32 , 33 , 34 ]. Jahan et al [ 8 ] and Dewi et al [ 12 ] evaluated Nypa fruticans wastes, namely nipa palm fronds (NPFs) and petioles, as pulping materials without prehydrolysis and bleaching. A previous study obtained a low pulp yield of 36.2–37.2% based on the raw materials as well as a high residual lignin content of 27.2–29.1 using the soda-AQ and kraft processes because the conditions were not optimal.…”

The search for alternative methods for the production of new materials or fuel from renewable and sustainable biomass feedstocks has gained increasing attention. In this study, Nypa fruticans (nipa palm) fronds from agricultural residues were evaluated to produce pure cellulose by combining prehydrolysis for 1–3 h at 150 °C, sulfur-free soda cooking for 1–1.5 h at 160 °C with 13–25% active alkali (AA), 0.1% soluble anthraquinone (SAQ) catalyst, and three-stage totally chlorine-free (TCF) bleaching, namely oxygen, peroxymonosulfuric acid, and alkaline hydrogen peroxide stages. The optimal conditions were 3 h prehydrolysis and 1.5 h cooking with 20% AA. Soda cooking with SAQ was better than the kraft and soda process without SAQ. The method decreased the kappa number as a residual lignin content index of pulp from 13.4 to 9.9–10.2 and improved the yields by approximately 6%. The TCF bleaching application produced pure cellulose with a brightness of 92.2% ISO, 94.8% α-cellulose, viscosity of 7.9 cP, and 0.2% ash content. These findings show that nipa palm fronds can be used to produce pure cellulose, serving as a dissolving pulp grade for viscose rayon and cellulose derivatives.

“…The bacteria or fungi used in delignification are usually commercial microbial inoculants containing yeasts, lactic acid bacteria, and photosynthetic bacteria, such as Lactobacillus sp., Streptomyces sp., and Actinomycetes sp. (Dewi et al, 2018). The biological degradation of solid organic materials consumes low energy and is environmentally and budget-friendly (Dewi et al, 2018;Fan et al, 2018).…”

Empty fruit bunch (EFB) enhances biogas production in the anaerobic digestion of palm oil mill effluent (POME) by acting as a co-substrate. Yet, lignin in EFB inhibits the performance boost. Therefore, EFB was delignified before using it as a co-substrate as much as 4%. This study compared three delignification techniques using the pairwise comparison method: Bacterial, chemical, and hydrothermal. Three parameter variations were selected for each method, namely bacterial concentration, molar concentration, and temperatures. Chemical delignification at a NaOH concentration of 2 M yielded the largest production of biogas and methane (302.0 and 153.8 mL, respectively), followed by hydrothermal at 180°C (260.0 and 83.8 mL, respectively). Although bacterial delignification required a long time (2 weeks), it was the simplest to implement and yielded the largest lignin reduction. However, the bacterial method yielded lower biogas (103-204 mL) than hydrothermal and chemical, probably because of lower hemi-and cellulose contents. Based on biogas and methane yield, production hazards, preparation time, and required infrastructure, chemical delignification was selected as the best method because of its gas production, followed closely by hydrothermal due to its efficiency and safety.
