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...

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...

Wood-plastic composites (WPCs) are very promising and sustainable green materials to achieve durability without using toxic chemicals. These materials, produced by blending biopolymers and natural fillers, permit us not only to tailor the desired properties of materials according to the...

In this study, kiri wood (Paulownia spp.) is assessed as potential core layer material for blockboards. Blockboards with core layers made of kiri and spruce (Picea abies) were produced using Anthocephalus cadamba as crossband veneer and beech (Fagus sylvatica) as face veneer. With spruce as core...

Deep penetration into wood is necessary for wood preservatives to provide long-term durability and for some wood modification agents to enhance wood properties. Bioincising was investigated as a means to enhance chemical penetration. Candidate fungi were screened for bioincising on pine and spruce...

Small specimens of spruce wood with different degrees of delignification were studied using in-situ tensile tests and simultaneous synchrotron X-ray diffraction to reveal the effect of delignification and densification on their tensile properties at relative humidities of 70-80%. In addition to...

The aim of this research was to investigate the physico-mechanical, thermal, and morphological properties of cement-bonded wood particleboards produced by using fly as has a partial cement replacement and spruce planer shavings. Experimental single-layer cement-bonded wood particleboards produced...

Various waste materials have energy potential. It is important to make use of this potential and prepare the product for further use by treating the waste. Treatments such as compressing waste into pellets leads to increasing the energy density of this fuel, which benefits transport and storage...

The increasing demand on the wood market makes it necessary to use all secondary resources, including the wood branches and spindles. The properties of deciduous branches and softwood spindles were evaluated in order to create wood panels, highlighting the transverse texture with high value added....

In this study, the availability of PMDI resin for non-load bearing particleboard for use in humid conditions was investigated. For this purpose, PMDI resin was added to the middle layers of the boards at different participation rates (0% Control, 0.5, 0.75, 1, 1.5 and 2). Industrial chips used in...
