Phytosanitary treatment of roundwood for oversea shipping - on the suitability of dry heat treatment as alternative to climate-change effective fumigation
2024 - IRG/WP 24-50394
The transcontinental trade of roundwood requires thorough phytosanitary treatment to protect native flora and fauna against foreign pests. This is generally done by fumigating shipping containers packed with roundwood with sulfuryl fluoride, a potent greenhouse gas. After treatment, the gas is released into the atmosphere, causing massive emissions. Since 2017, the usage of sulfuryl fluoride in th...

DURALARCH – Suitability of selected coloured coniferous heartwoods of different origin for their use in outdoor applications
2025 - IRG/WP 25-11064
For outdoor above-ground applications with high demands on biological durability, there are only a few softwoods available that also have high density and strength characteristics. One of the most important timbers with these material properties is Siberian larch (Larix sibirica, Larix gmelinii), which is available in sufficient quantities due to its large distribution area. Imports of Siberian la...

Wood phytosanitation: which Standard should be applied?
2025 - IRG/WP 25-20748
The international Standards ISPM 15 and ISPM 39 are both essential tools for safeguarding global plant health, but they serve different purposes, and apply to different aspects of international trade. ISPM 15 focuses on wood packaging material and mandates Standardised treatments and marking, while ISPM 39 addresses international movement of wood and emphasises risk assessment and tailored phytosa...

Contribution of naturally durable wood use to Circular Economy - Understanding the classification system of natural durability and its variation within wood species
2025 - IRG/WP 25-50411
Total wood demand is shown by FAO to increase 49 percent between 2020 and 2050, regardless of deteriorating conditions such as deforestation and degradation due to fire and biological damages. Demand for wood as a building material is also projected by UNEP to increase significantly to 300 Gt in 2040. To address this situation, extension of the service life and re-use of wood are expected to make ...
