Oil palm empty fruit bunch (OPEFB) is considered the cheapest natural fiber with good properties and exists abundantly in Malaysia. It has great potential as an alternative main raw material to substitute woody plants. On the other hand, the well-known polymeric hydrogel has gathered a lot of interest due to its three-dimensional (3D) cross-linked network with high porosity. However, some issues regarding its performance like poor interfacial connectivity and mechanical strength have been raised, hence nanocellulose has been introduced. In this review, the plantation of oil palm in Malaysia is discussed to show the potential of OPEFB as a nanocellulose material in hydrogel production. Nanocellulose can be categorized into three nano-structured celluloses, which differ in the processing method. The most popular nanocellulose hydrogel processing methods are included in this review. The 3D printing method is taking the lead in current hydrogel production due to its high complexity and the need for hygiene products. Some of the latest advanced applications are discussed to show the high commercialization potential of nanocellulose hydrogel products. The authors also considered the challenges and future direction of nanocellulose hydrogel. OPEFB has met the requirements of the marketplace and product value chains as nanocellulose raw materials in hydrogel applications.

“…The decreasing of pH level possibly was attributed to the release of sulphonyl groups on eNC from adsorbent back to MO solution. However, our previous studies showed that the amount of sulphonyl groups release back to the treated water was insignificantly changed (Septevani et al, 2020). The results for TDS analysis both eNC and eMC showed that there was a significant decrease in the amount of TDS after adsorption for all the adsorbents which achieved up to 78% TDS reduction.…”

“…Meanwhile, rod-like nanocellulose was observed in the B-eMC ( Figure 1D) with the low aspect ratio of 13 at 10.7 ± 1.8 nm in width and 128.4 ± 17.2 nm in length. High purity of cellulose after bleaching (B-eMC) is postulated to be easier deconstruction into a smaller size compared to D-eMC which still contained complex structure of lignin and hemicellulose (Septevani et al, 2020). Adsorption MO onto EFB-NC The adsorption efficiency was determined by using UV spectrophotometry by comparing the concentration of MO before and after treatment of EFB adsorbent.…”

“…Raw e-EFB possesses a higher thermal stability as a note by lower percentage of weight losses, simply because it still contains many impurities including Silica to give a higher resistance at high temperature (Septevani et al, 2020). Further, eMC based adsorbent (D-eMC and B-eMC) exhibited a single-step and sharp decomposition with a greater weight loss compared to eNC samples (D-eNC and B-eNC).…”

“…EFB contains high cellulose about 43%, hemicellulose 24%, and lignin 21% Septevani et al, 2018). The high content of cellulose can be used as a potential advance material due to, low density, low abrasiveness, high biodegradable capability and recently reported as effective adsorption capacity (Septevani et al, 2018;Septevani et al, 2020).…”

The purpose of this research is to determine the adsorption capability of micro and nano-cellulose derived from oil palm empty fruit bunch (EFB) as dye removal. Cellulose based adsorbents were successfully obtained from EFB in the form of microcellulose (eMC) via both delignification (D-eMC) and bleaching processes (B-eMC) as well as in nanocellulose (eNC) by using acid hydrolysis method and hence termed as delignified-eNC (D-eNC) and bleached-eNC (B-eNC) respectively. Dye adsorption test was carried out by UV-Spectrophotometer by comparing initial dye MO concentration (as a control solution) to the treated MO solution upon the addition of micro- and nano- cellulose based adsorbent. It was clear that the dye removal efficiency of micro-cellulose both D-eMC and B-eMC were lower than the nano-cellulose structures. The higher adsorptive capacity of nano-size cellulose compared to the micro-size cellulose was confirmed by the distinct presence of FTIR shifting peak of hydroxyl and sulfonyl groups. It was expected as the micro-size of cellulose would not be able to provide a good adsorptive capability of hydroxyl surface active agent to adsorb the dye. In the case of eNC, the result showed that D-eNC afforded a better dye adsorption than B-eNC. At the same concentration of eNC at 3 wt. %, D-eNC could adsorb at about 19.3% of MO while only 2.4% of MO could be removed by B-eNC. Finally, all of adsorbent could maintain pH and TDS within water quality specification.
