Aspen (Populus tremula L.) represents an important resource in France as far as standing wood is concerned. It often remains used for the manufacturing of pulpwood and fuelwood because no physico-chemical properties have been established. To date, PANIBOIS has used this species for manufacturing...

Ethanol extraction of lignocellulosic biomass under mild conditions has re-attracted considerable attention since a light-colored lignin with low molecular weight can be obtained. Unfortunately, the yield of isolated lignin for the ethanol extraction process is very limited. To enhance the...

Production of particleboards is associated with volatile organic compounds emissions, many of which have odorous properties. The objective is to determine whether the odor emissions from the production, using spruce and aspen as raw material, comply with the local odor limit defined in a specific...

Thermal radiation properties of natural wood are mainly affected by its chemical composition and physical structure. In the atmospheric transparency window (8-13 µm), cellulose, hemicellulose and lignin all have high average emissivity of 95.77%, 96.83% and 97.22%, respectively. This allows wood to ...

The paper investigates the CNC routering protocol by using advanced software for designing, simulation and processing wooden based materials, in order to obtain perforated decorations. The tests were performed on specimens made of three types of materials, namely spruce wood, poplar plywood and...

Lignin-based phenolic resin(LPF)with high phenol substitution rate(≥70%) were synthesized based on alkali lignin(UL)from black liquor of kraft pulping of spruce, or based on demethylated lignin(DUL) and hydroxymethylated lignin(HUL) obtained from the modification of UL. The effects of the hydroxyl...

The traditional poplar cultivation does not represent the only way to produce poplar wood: new market opportunities and new more sustainable cultivation models are appearing on the international scene. We are only reconsidering past solutions in a mo-dern key and with new knowledges and...

Recently, a nanoscale structuring effect on the wood surface after plasma treatment by diffuse coplanar surface barrier discharge was observed. This type of discharge was applied to the treatment of aspen (Populus tremuloides) and thermally modified aspen wood, and the effect of treatment time and...

High performance fibers are widely applied to wood-based composites as reinforcement to improve mechanical performance of composites. Design and mechanical performance tests of basalt fiber cloth reinforced bamboo and poplar veneer (BFRBV) composite are presented in this paper. The fiber surface...

Wood permeability and compressibility are affected by cell wall structure and chemical composition. These properties can be improved by appropriate wood pretreatments. Low-density poplar wood was converted to a more dense structure by the following steps: First, lignin and hemicellulose were...
