Eucalyptus sp. is the most important planted crop for production of chemical pulp. This pulp mostly bleached with chlorine dioxide, which produces hypochlorous acid in situ when reacting lignin. However, applying hypochlorus directly not practiced, even though it contributes significantly to bleaching reactions. Therefore, this article presents as main oxygen delignified kraft The results showe...

This paper aimed to determine the quality indexes for and cellulose based on fiber features from two wood species of interest, Eucalyptus pellita E. tereticornis. The mean annual increment (IMA) was calculated by measuring DBH Height (25 years), a 10 cm disk each tree collected density determinations anatomical studies paper. Tree height, trunk diameter at 1.30 m in height (DBH), volume per wer...

The economic importance of some Eucalyptus species, including interspecific hybrids, has been extended from the traditional interest of pulp and paper production to the emergent areas of bio-fuels and bio-materials. New genomic resources and high throughput technologies have provided the Eucalyptus research international community with the opportunities to identify genomic regions of interest i...

Abstract Pulp and paper wood plantations are one of the substantial forestry estates in Indonesia that usually integrated with a pulp mill industry. The atmospheric condition glasshouse gases keep increasing primarily due to anthropogenic activities represent critical issues on human health affect forest productivity. Therefore this study measured concentration common pulpwood plantation Riau P...

Abstract Xylan is the main contaminant of hardwood sulphite dissolving pulp used for production regenerated cellulose. The amount xylan in should not exceed minimum allowable values and which easy to achieve. To control pulping process, a basic knowledge removal essential. In this study, Eucalyptus globulus glucuronoxylan (GX) conversion during acidic Mg-base acid was assessed first time pilot ...
