Characterization and evaluation of Paulownia elongota as a raw material for paper production
(2008-11-19) Ates S.; Ni Y.; Akgul M.; Tozluoglu A.
Paulownia elongota, one of the most fast growing species of the world, was evaluated as raw material for pulp and paper production. The chemical, morphological and anatomical aspects of paulownia wood were determined. The lignin, holocellulose and α-cellulose contents in P. elongota wood were comparable to those of some common non-wood and hardwood raw materials. Different chemical pulping procedures were applied to P. elongota wood to evaluate its pulping potential. Paper strength properties and acidic group content bound to the cell wall were determined. The alkali solubility, water solubility and alcohol-benzene extractive content were higher than those from wood and most nonwoods. The fiber length of 0.83 mm was observed, which is close to low end of the hardwoods but fiber diameter was very wide, similar to that of softwoods. The pulpability of paulownia wood was also studied. The pulp yield and viscosity were very low and the kappa numbers were high. The strength properties were comparable to those of some wood and non-wood pulps. Although, paulownia pulps are considered as low quality materials, it can be used for paper production when mixed with long fibrous materials. © 2008 Academic Journals.

With the increase in social environmental consciousness, the interest in the production of cellulose-based nanomaterials from renewable natural resources has swiftly increased in recent years. Renewable nanotechnology displays distinguished properties of traditional petroleum-based materials, and also creates new properties such as renewability, biocompatibility, and biodegradability. Nanocellulosic materials allow the design of special materials with high performance that can eliminate present environmental and sustainability problems. Growing interest in such new generation products, which are called bio-based nanomaterials, will substitute conventional petroleum-based materials because of fluctuations in oil prices and scarcity of sources. The generation of these new nanomaterials will lead to the production of materials with high performance while eliminating environmental problems. This chapter presents a unique literature survey on the production methods, characterization, and modification of nanocellulose, and also on the effects of nanocellulose as a coating and additive material on paper and board.
