In this study, we investigated the physical properties of kraft pulps made from rice husk, peanut husk andgarlic stems. These agricultural byproducts were collected individually, and then various pulps weremanufactured from them by controlling active alkali, sulfidity, reaction time and the liquor ratio in thekraft pulping process in order to analyze the applicability of these agricultural byproducts as raw materialsfor kraft pulps. After kraft pulping, we measured yield, flake content, fiber length, fiber width andfreeness of pulps, and the fiber shapes of the pulps were observed by using an optical microscope.

When the higher active alkali, longer reaction time and lower liquor ratio were applied in kraft pulpingprocess, reject content decreased and fiber yield increased. The pulp from garlic stems had the longestfiber length and that from rice husk showed the highest intial freeness. All of the pulps from agriculturalbyproducts showed higher initial freeness, shorter fiber length and the similar fiber width compared toOCC, BCTMP and hardwood BKP. The fibers of the pulps made from agricultural byproducts showeda similar shape to those of commercial pulps. It was concluded that these agricultural byproducts had apotential as raw materials to produce an alternative pulp to the commercial pulps.
