“…To increase the lignin purity, some techniques have been employed such as various washing treatment frequencies during the isolation process [17,18] or the fractionation step [19]. Other than that, pretreatment before delignification has successfully improved the lignin yield by removing extractives attached to biomass such as in areca leaf sheath (ALS) [20].…”

Lignin, a naturally abundant aromatic polymer of natural origin, offers numerous desired intrinsic properties belonging to rich functional groups. However, the lignin properties vary influenced by the source of biomass (hardwood, softwood, and herbaceous) with different monomer unit proportions, delignification methods, and isolation techniques. To extract lignin, two routes have been introduced i.e. cellulose first fractionation and lignin first fractionation. The focus of this review is revisiting the strategy of cellulose first fractionation in which lignin is mainly present as a side product of the delignification process via the sulfur-bearing process and the non-sulfur-bearing process. After that process, the isolation process was employed in black liquor as a by-product of the process. By this route, technical lignin is produced with the potential to convert into biomaterial feedstocks. The main property concern of this lignin is its condensed structure which requires further modification for specific purposes. Physical and chemical modification can be introduced to increase the reactivity of lignin to widen the application

This study investigated the use of sodium carbonate pulping in oil palm empty fruit bunch (OPEFB) pulp production for paperboard manufacturing. The pulping varying the active alkali (AA) (4.5 %, 6.5 %, 8.5 %), NaOH fraction (F) (10 %, 20 %, 30 %), and cooking time (T) (30′, 60′, 90′). The performance was evaluated based on screened pulp yield, kappa number, and delignification selectivity. Furthermore, the functional groups, S/G ratio, and morphological structure of the optimum pulp were observed. The tensile and tear indices of the OPEFB pulp paperboard were also measured. The results suggest sodium carbonate pulping at a low chemical dose successfully produced OPEFB pulp. Based on the highest delignification selectivity value of 12.74, the most effective pulping conditions were achieved with AA-6.5 %, F-30 %, and T-90′. The optimum OPEFB pulp analysis revealed a decrease in lignin proportion with the dominant degradation of the syringyl unit. Thus, the fibers are easily separable during mechanical treatment. These characteristics influenced the paperboard, resulting high tensile and tear indices of 7.90–8.15 Nm g−1 and 15.09–16.25 mN m2 g−1, respectively. Overall, this study demonstrated the potential of sodium carbonate pulping to produce high-quality pulp and paperboard from OPEFBs, highlighting the thoroughness of the research process in the pulp and paper manufacturing field.
