Ash and lignin content of Kenaf (Hibiscus cannabinus) / Rosnizam Ramli

The percentage of lignin content and ash content in Kenaf (Hibiscus cannabinus) was determined from segment stem and branch in accordance to TAPPI standard. In both cases, the segment of stem exhibited higher value for ash and lignin content when compared to those segments at the branch. Lignin content ranged from 20% to 24% and the ash content ranged from 1.0% to 3.0%. These values of high lignin and low ash content could serve as good indication for better utilization especially when machining and chemical pulping. On the other hand, wood with high lignin content would influence bleaching during pulping process.
