10 Liquefaction of ligno-cellulosic biomass is one of the chemical conversion technologies for 11 developing new materials, adhesives and energy systems. The liquefaction process also 12 provides an opportunity to utilize ligno–cellulosic wastes such as saw-dust, woody wastes, 13 branches and twigs, agro-residues, etc. for the development of value added products. This 14 paper presents the liqu...

Interest in 3D printing has greatly increased since 2013. With 3D printing high part complexity at no additional costs can be achieved, beside of efficiently using the raw material. This article reviews recent developments in 3D printing, with respect to the use of wood. Three examples are given on how wood could come to 3D printing: development of bio-based filaments, printing wood-like 3D obj...

The design and analysis of many products is performed with imprecisely known parameters, relationships, and environmental conditions. This is especially true for wood products which exhibit greater variability than most materials. Fuzzy set theory applied to the design and analysis of wood products is regarded as a promising approach for modeling the geometric and mechanical property variabilit...

The objective of this work was to study Cr(VI) sorption/desorption on two by-products from the wood industry: pine sawdust and oak wood ash. The retention/release experiments were carried out using standard batch-type trials. In the sorption-phase experiments, pine sawdust showed 23% sorption when a concentration of 100 mg Cr(VI)ŸL-1 was added, whereas sorption on oak wood ash was 17%. In the d...

Background: Laboratory leaching tests on treated wood were performed during a European robustness study in the framework of the validation of a tank leaching test procedure that has been proposed for construction products in order to determine the potential release of dangerous substances which can be transferred to soil and groundwater. The release of substances has to be determined also for m...

BACKGROUND The objective of this study was to demonstrate a new, cost-effective method to define the sustainable amounts of harvested wood products in Southeast Asian countries case studies, while avoiding degradation (net loss) of total wood carbon stocks. Satellite remote sensing from the MODIS sensor was used in the CASA (Carnegie Ames Stanford Approach) carbon cycle model to map forest prod...

Some Parties (Countries) to the UNFCCC decided to include the carbon uptake by harvested wood products (HWP) in a new general accounting framework after 2012 (post Kyoto). The analysis aims to make a comparison between the cascaded use of HWP and the use of wood for energy. We combine the new HWP framework with an assumed increased 50 million m harvest level in Canada and evaluate the impact of...

Aims to valuate Africa's forestry and forest products, namely Wood Forest Products (WFPs) Non-wood (NWFPs) in the sixteen (16) West African countries.The study identified a systematic assessment of most common products (wood non-wood products) considering available data on national reserves selected countries Africa. The also revealed need for biodiversity conservation help mitigate impact glob...

BACKGROUND The forestry and wood products industries play a significant role in CO2 emissions reduction by increasing carbon stocks in living forest biomass and wood products. Moreover, wood can substitute for fossil fuels. Different methods can be used to assess the impact of regional forestry and wood products industries on regional CO2 emissions. This article considers three of those methods...

Issue: Pulp and paper industry were originally designed and constructed to use virgin wood feedstocks as a raw material. Some of the virgin wood fiber used for the pulp and paper industry is from lower value roundwood logs that are chipped for pulping. The other major source is from the residuals from sawmill, veneer, and lumber plants. These solid wood production plants produce millions of ton...
