Chemical composition and performances of slow pyrolysis by-product from sugarcane bagasse for wood protection
2020 - IRG/WP 20-30752
Pyrolysis distillate or bio-oil, a by-product of biomasses’ slow pyrolysis in the char-making process, has been traditionally used as bio-pesticides by Asian farmers. Due to its large composition of bio-active chemicals, bio-oil obtained from various biomass has become of interest in many applications, including wood protectants. This study aims to characterize the chemical composition of bio-oi...

Durability of fast- and slow-grown Douglas fir in above ground exposures in Australia
2023 - IRG/WP 23-11009
Natural durability is a key property for untreated timber used outdoors and exposed to the weather. The natural durability of fast- and slow-grown Douglas fir heartwood was compared in an above-ground L-joint field test near Brisbane, Queensland, Australia. The L-joint test provides conditions that are favourable to decay. Fast-grown (regrowth) Douglas fir had ≤ 10 growth rings per 50 mm, while ...

Unlocking the potential of tropical fast-growing hardwood species
2023 - IRG/WP 23-11010
Social forestry or community managed forestry practices have been promoted as an inclusive way to mitigate climate change through the framework of the UNFCCC scheme of the Reduce Emission Deforestation and forest Degradation (REDD+) programme. Fast growing wood species are one of the least tapped social forestry commodities in Southeast Asia, and they have the potential to be upscaled to meet the ...

Potential co-valorization of pyrolysis tars from five wood species form Tunisia as wood preservatives bases: Chemical compositions, antifungal and anti-termite activities
2025 - IRG/WP 25-20739
The pyrolysis of five Tunisian wood species (Ceratonia siliqua, Eucalyptus camaldulensis, Eucalyptus maidenii, Pinus pinea, and Quercus canariensis) was carried out in a custom-designed carbonisation reactor developed at the INRGREF's Wood Technology Section (Tunis, Tunisia). This process aimed to produce both char and pyrolysis by-products, particularly pyrolysis oils. The experiments were conduc...

Decay resistance of thermally modified Eucalyptus grandis in closed and open systems
2025 - IRG/WP 25-30815
Thermal modification has been successfully used to improve the durability of Eucalyptus wood from fast-growing forests. Although it is the most common type of modification process, there are some fields for studies on thermally modified wood, particularly about the comparison between processes in closed and open systems. This work aimed to analyse the effect of thermal modification in closed and o...

Enhanced Termite Resistance of Low Durability Fast Growing Teak Wood by Non-Biocide Treatments Based on Chemical and Thermal Modification
2025 - IRG/WP 25-30818
Short rotation teak as a fast-growing tree can be considered as a renewable material resource for the future green economy. However, short rotation teak wood is susceptible to biodeterioration, particularly to termite attack. The objective of this work was to investigate the effect of chemical and thermal treatment on resistance of sapwood, transition wood, and heartwood of short rotation teak aga...
