Eucalyptus is a species of great interest for the pulp and paper industry. Worldwide there are 20 million hectares planted and within Chile a total of 700.000 ha, being the main species grown for short-fibre pulp Eucalyptus globulus, which is extensively used for pulping due to its fast growth, high pulp yield, and good fiber properties. Genetic programs of this specie have been oriented in imp...

EXTENDED ABSTRACT As any mature industry the forest industries have gone through many transformations and structural changes. Historically, forest industries in the Northern hemisphere (North America and Northern European countries) have been rather successful by moving forward in the value chain in order to avoid market decline or raw material shortage (Hylander 2009). From timber exports and ...

Pulp and paper effluents are considered as serious environmental hazards and their treatment, because of multiplicity of impurities and complexity of their chemical structures, is one of the most difficult and inconvenient industrial processes. As the most pulp and paper mill work on kraft process, there are few studies in literature on the treatment of neural sulfite semi chemical (NSSC) p...

Water requirement to meet agriculture, domestic, industrial and other demands indicate the need for regeneration of waste water. Industrial waste water is being used in dry areas. Waste water of pulp and paper industry (brown with unpleasant smell) is usually alkaline in nature, has high suspended solids, total solids, COD, BOD and toxic odorous substances. It was observed in the study areas th...

Pulp and paper mills are increasingly implementing process information systems with the goal of better tracking, troubleshooting and optimizing their processes. In the field of process engineering as well as in the field of business process engineering, these information systems are playing an increasingly important role. However, their potential is far from being fully exploited, in large part...

Surface-Enhanced Raman Spectroscopy (SERS) enables the investigation of samples with weak specific Raman signals, such as opaque samples, including fruit juices and pulp. In this paper, biological apple juices and apple/pear pulp have been studied in order to evidence the presence of fructose and pectin, which are components of great relevance for quality assessment of these kinds of products. ...

Thermoplastic composite materials containing wood fibers are gaining increasing interest in the manufacturing industry. One approach is to use nano- or micro-size cellulosic fibrils as additives and to improve the mechanical properties obtainable with only small fibril loadings by exploiting the high aspect ratio and surface area of nanocellulose. In this study, we used four different wood cell...
