The use of cross-laminated lumber (CLT) for building construction has gained interest in the US and Canada. Although anecdotal market size claims exist, few quantitative studies have estimated the potential market size or discussed the impact of CLT on lumber supply. This paper presents a method to quantify CLT markets and lumber supplies based on data for the Northwest US.

The objective of this study was to assess the biochemical and thermochemical energy conversion potential of decaying hardwoods and compare their relationships with external and internal indicators of tree degradation.

Screen the oak seedlings in three consecutive years, use a newly established virus-specific diagnostic reverse transcription polymerase chain reaction (RT-PCR) and find out the causes and impact of oak decline so that it would be possible to reforest high-quality seedlings of oak successfully in a time of climate change.

The successful application of paulownia for furniture manufacturing will depend on its supply volume and economics in the future.

Birch has been extensively used by the veneer-based industry, but species like black alder, grey alder and aspen have not been commonly used by the veneer-based products industry due to the lower quality of this resource. It was found that with proper lay-up schemes, these wood species could be successfully used by the veneer-based products industry.

However, veneer-based mass-panel (VBMP) systems could offer additional benefits including the more efficient use of the available forest resources to produce wood-based mass-panels (WBMPs) that have equivalent to superior performance to CLT.

This study analyses the existing road surfaces constructed on timber log foundations and the selected properties of the wood taken from designated road sections—to measure the properties of durability.

From the results obtained, it was found that overall carbon emission was a net gain for Sarawak.

However, for wood to meet its full potential, researchers must overcome the challenge of understanding its fundamental moisture-related properties across its many levels of hierarchy spanning from the molecular scale up to the bulk wood level.
