Forest volume estimation and yield prediction. Moreover, all of the investigated tensile properties of paper made from ‘Hybrid ’ pulp were higher than for paper produced from birch pulp.
Fast growing grasses, despite lower pulp yield ( to %), showed comparable tensile properties to birch. Therefore, these pulps are promising raw materials for papermaking. Biermann's Handbook of Pulp and Paper: Raw Material and Pulp Making, Third Edition is a comprehensive reference for industry and academia covering the entire gamut of pulping technology.
This book provides a thorough introduction to the entire technology of pulp manufacture; features chapters covering all aspects of pulping from wood handling. The pulping of these six mangrove species was also carried out by kraft process and papermaking properties were also evaluated.
Pulp yield was lower and kappa number was higher as compared with other tropical hardwoods. But the physical properties of these species Cited by: 1. The chemistry. Acacia mangium wood, a prominent fast-growing plantation species used in the pulp and paper industry, has been studied to quantify and structurally characterize the lignin, xylan and cellulose by Pinto Table 1 summarizes the general chemical composition of Acacia mangium Size: 80KB.
a sustainable basis is to obtain wood from social and farm forestry plantations (Kulkarni, ). The small paper mills set up in the early seventies almost exclusively use agricultural wastes as raw material for paper production whereas large mills mainly Eucalypts in pulp and paper industry 0 5 10 15 20 25 30 35 Chemicals Raw material Power File Size: 2MB.
Two most important properties of any papermaking cellulosic raw material are, how much cellulose fiber it has and how long the fibers are. The amount of cellulose fiber in wood determines the pulp yield, ease of pulping and cost of pulp produced. The importance of fiber length is explained in pulp properties.
The maximum average fiber length. Keywords：fast growing tree, papermaking, kraft pulping, soda-AQ pulping 1. Introduction For the past years, the utilization of fast growing trees as raw materials has become popular in the pulp and paper industry. Fast growing tree species can be grown in plantations and thus, a manageable.
The ones that now grow wood are set up to have rapidly growing crops of trees that can be used for logging and with suitable remnants for paper, pulp and fiber. Another name for the product grown with this farming technique is "fast wood." Forestry specialists have helped to establish these fast wood.
The properties of wood depend on growth factors, such as the location of the tree from which it came and its location within the tree. Trees growing on wet, warm, and sunny locations are fast-growing and have coarse, stiff fibers, whereas trees growing on dry, cold, and less sunny locations are slow-growing and have fine, dense fibers.

The chemical composition would not obviously cause major problems in pulping processes. Eucalyptus globulus is one of the most important hardwood species used by the pulp and paper industry due to its high pulp yield, high wood density, excellent fibre quality and good handsheet.
Summary Four species of fast growing annual plant viz. Hibiscus sabdariffa, Crotalaria juncea, Tephrosia candida and Hibiscus cannabinus and a variety of reed, Neyraudia reynaudiana were evaluated in the laboratory for their pulp and paper making properties.
Data on proximate chemical analysis of raw materials. The influence of the pulping variables (active alkali charge, sulfidity, temperature and pulping time) on the pulp yield, Kappa number and strength properties of Acacia mangium kraft pulp was examined.
The dissolution of wood components was seen as particularly sensitive to the variations produced in active alkali charge and cooking temperature. Get this from a library. Pulping and paper-making properties of fast-growing plantation wood species.
[Food and Agriculture Organization of the United Nations.]. The first of these reasons, and maybe of paramount importance, is the lower price of the short Eucalyptus fibers, as compared to the long softwood fibers.
This price relationship is perfectly understandable and justified. Much less wood is consumed to produce one ton. Pulping and papermaking properties of fast-growing plantation wood species.

While in theory, any tree can be used for pulp-making, coniferous trees are preferred because the cellulose fibers in the pulp of these species are longer, and therefore make stronger paper. Some of the most commonly used softwood trees for paper making include spruce, pine, fir, larch and hemlock, and hardwoods such as Pulp category: Production [M ton].
Neto, a,b). Trema orientalis is also a fast-growing species and can be harvested in 3–4 years for valuable pulpwood (Jahan and Mun, ). Many studies have been carried out to evaluate some fast growing wood species for the pulp and paper industry (Edgrard, ; Fidel and Tamayo, ; Jahan and Mun,; Ja.
