Abstract: This research finding was aimed at determining the pulp and paper potential of sap stained oil palm fronds rachis vascular bundles (OPFB) using an ecofriendly alkaline peroxide pulping. Alkaline peroxide pulping (APP), which combines both pulping and brightening actions into a single process, was attempted on sap stained oil palm frond rachis vascular bundles (OPFB). After the maceration of the raw samples, a total of two hundred fibres were randomly examined under light microscope and the mean values of their morphological dimensions were recorded. The obtained data was utilized to calculate the felting rate, flexibility coefficient, Rigidity coefficient, Runkel index and rigidity index. The effects of these properties on paper strength were equally evaluated.
