Cellulosic solid residual, which is the by-product of oil palm empty fruit bunch (OPEFB)-xylan extraction process, was evaluated in terms of cellulose recovery by eco-friendly approach. The OPEFB-fibre was initially treated with alkaline for xylan extraction. The resulting solid residue was dried before treated with mild concentration of bleaching agents of 20% (v/v) formic acid and 5% (v/v) hydrogen peroxide at 85°C for the extraction of cellulose. α-cellulose content of 84.16±0.4% was achieved. Fourier transform infrared spectroscopy (FTIR) analysis showed that the products obtained have the standard cellulose structure and functional group. The crystalline nature of the extracted cellulose, as proven by X-ray diffractometer (XRD) has crystallinity index and crystalline size of 54.4% and 5.5 nm, respectively, whereas the thermogravimetric analysis (TGA) indicates the sample purity in terms of thermal stability at 370°C by comparing the results to commercially available cellulose. Meanwhile, scanning electron microscope (SEM) observation showed that the extracted cellulose morphology is in the form of separated fibrils. In terms of impurities, trace elemental analysis showed the presence of phosphorus (P) as the major element but the quantity of fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and sulphur (S) detected on the cellulose was insignificant.
