Abstract
This study investigated the effect of bamboo nodes on the properties of paper produced from Kawayan Kiling (Bambusa vulgaris Schrad.), a widely cultivated bamboo species that has a potential for pulp and papermaking. The chemical composition and fiber characteristics of the bamboo nodes and internodes were compared and evaluated as well as the strength properties of the paper produced from the (1) the internodes only and (2) the mixture of nodes and internodes. Results show that the pulp and papermaking properties of the internodes of B. vulgaris compare favorably with those of the different hardwood and softwood species which are suitable for pulp and papermaking. It was also found that the paper produced from the internodes generally has better strength properties than that produced from the mixture. With this, the additional cost of removing the nodes of the bamboo prior to pulping was estimated. The amount needed to invest for bamboo cross-cutting machines is Php 212,400, and Php 3,188.16 and Php 19,200.00 are needed per day for the labor and energy cost, respectively.
