“…The decrease in brightness at high concentrations of the AP liquor is attributable to the redeposition of the alkaline leachate on the surface of the biomass hence resulting to the phenomenon of alkaline darkening. This is similar to the observation reported by Liu and co-workers [24].…”

This chapter explores the potentials of the alkaline peroxide pre-treated oil palm vascular bundle (oil palm waste) in the industrial production of pulp, paper and other cellulosic products like microcrystalline cellulose. Management of this escalating waste is a herculean task and creates environmental hazards hence urgent action is needed to create value out of these waste biomass. The pulp and paper industry being a large consumer of lignocellulose materials preferred the use of coniferous and deciduous trees for pulp production and papermaking because their cellulose fibres in the pulp make durable paper. In addition to this, the global population explosion and the economic development has resulted in the significant increase in demand for paper. With improvements in pulp processing technology through the use of environmental benign technology like alkaline peroxide pre-treatment it has been considered as suitable for paper pulp and other cellulose based products such as microcrystalline cellulose. Characterization of the alkaline peroxide pre-treated oil palm vascular bundles using the scanning electron microscope (SEM), Fourier transmission infra-red (FTIR) spectroscopy and X-Ray Diffraction (XRD) analyses confirm the micro-sized cellulose fibres. Use of these lignocellulosic materials can reduce the burden on the forest while supporting the natural biodiversity.

“…The tensile index and tightness of paper made from the 29°SR aspen APMP synchronously increased with the increase in DCSP as shown in Table 4. The result of DCSP addition to aspen APMP was similar to that of the extraction of hemicellulose prior to aspen chemithermomechanical pulping in that it reduces the tensile index of paper (Liu et al 2012). The effect of DCSP on the APMP may be similar to the impact of fines on mechanical pulp (Moss and Retulainen 1997).…”

Corn stalk rind (CSR) was treated with Trametes hirsuta lg-9 and then refined into pulp. The biotreatment resulted in loss of paper strength and brightness, but energy consumption during refining (ECR) was reduced. Meanwhile, multiple linear regression was carried out, for which ECR served as the dependent variable, and the yield and infrared relative absorbance intensities at 3414 cm -1 and 1653 cm -1 of the biotreated CSR served as independent variables. Results showed that the determining parameters of the biotreated CSR may be used to predict the ECR. In this work, delignified corn stalk pith (CSP) was added to aspen alkaline hydrogen peroxide mechanical pulp (APMP). The CSP enhanced the strength properties of the aspen APMP and inhibited yellowing. The biomechanical pulping of CSR has the potential to produce a low-cost green pulp, and the delignified CSP can serve as a pulp additive.
