Descripción
Trema orientalis L. is a fast growing tree in tropic and sub-tropic region. Traditionally, leaf, bark and root extract of T. orientalis is being used in therapeutic purpose in different part of the world. Leaf, root and bark extract of T. orientalis also shows antioxidant and antibacterial activity. T. orientalis bark contains 22% tannin material and suitable for leather tanning. Tannin from bark also can be used in in biobased resin preparation. Wood from T. orientalis had good amount of α–cellulose (45-50%) and moderate amount of (20-25%). Many researches were carried out research on T. orientalis pulping. In the chemical pulping processes, the pulp yield was about 50% with kappa number around 18-25. The papermaking properties of T. orientalis pulp were comparable to tropical hardwood pulp. Dissolving grade pulp with high purity could also be produced from this species. This species can be a good alternative for pulpwood production in tropical countries. A complete utilization of tree in biobased products development is possible through T. orientalis.
