Study of the use of organosolv lignin as bio-preservative of wood
2012 - IRG/WP 12-30603
The service life of wood depends on the species, use and environmental conditions of exposure. The treatment of wood protects it against degradation by xylophagous agents, enhancing the durability of material up to 10 times, and reducing the deforestation around 12.5%. In this way, the use of treatments is necessary because increases the service life of material and protect against xylophagous age...

Chestnut tannin-furfurylic resins for wood preservation: influence of the proportion of tannins as a copolymer
2025 - IRG/WP 25-30816
Tannin, which is present in all plants, is the most abundant polyphenol globally and can be extracted using water or organic solvents such as acetone, ethanol and methanol. Tannins are classified into two categories: condensed tannins (catechin-based polymers) and hydrolysable tannins (sugar esters with galloyl units). Previous studies have demonstrated its potential as a raw material for modifyin...

Modification of Beech Wood by Furfurylation with Chestnut (Castanea sativa) or Acacia (Acacia mearnsii) Tannins for Protection Against Subterranean Termites
2025 - IRG/WP 25-30832
Environmental concerns about tropical deforestation have emphasised the need to source wood from sustainably managed forests. At the same time, competition from alternative materials has amplified the demand for high-quality wood-based products that meet contemporary expectations. To date, most preservative treatments have involved impregnating wood with biocides, often derived from petrochemicals...
