Optimization of oxalic acid production for bioleaching of metal components from CCA-treated wood by an unknown Polyporales sp. KUC8959
2010 - IRG/WP 10-50266
A brown-rot fungus, an unknown Polyporales sp. KUC8959, has recently been identified and proven as a prominent fungal species for bioremediation of CCA-treated wood wastes in our Lab. The fungus produced a larger amount of oxalic acid than other fungi tested, and removed 90 % or more of chromium, copper and arsenic from CCA-treated wood sawdust through bioleaching process. The bioleaching process ...

Optimization of the bi-oleothermal treatment process for wood preservation and fireproofing
2011 - IRG/WP 11-40566
The bi-oleothermal© process (combination of oil and heat treatment) is a well mastered alternative method for wood protection. However, the fire behavior and resistance to decay of bi-oleothermally treated wood are not good enough to ensure performance which meets the service standards for outdoor applications such as cladding or decking expected by the market. The aim of the present research pro...

A Green and Novel Technology for Recovering Copper and Wood from Treated Wood Waste – Part II: Optimization, copper metal recovery, and process design
2017 - IRG/WP 17-50326
The US consumes 70 million pounds of copper and produces 580 million cubic feet treated wood annually. The EPA disallows burning and reusing treated wood waste due to health/environmental concerns. Vast quantities of copper and wood are landfilled. Two safe and low cost extraction systems, citric acid and ammonium citrate, were identified in Part I of this study. In Part II of the study, effects o...

Optimization via artificial intelligence of intumescent coatings for wood substrates
2023 - IRG/WP 23-40987
The development of new materials requires a large amount of experiments representing a major issue to innovate. This is particularly true for complex material formulations such as flame retarded materials that could contain a number of ingredients. Artificial Intelligence based optimization (more precisely Bayesian optimization) techniques appear to be efficient methods to optimize complex systems...

Optimization of furfurylic alcohol/tannin ratio to improve the performance of biosourced thermoset resins for wood protection
2023 - IRG/WP 23-40994
This study concerns the chemical modification of wood with different ratios of tannin and furfuryl alcohol (FA) in the presence of maleic acid as catalyst. Tannins were used not only as cross-linking agents, but also as co-monomers to improve wood durability, while reducing the amount of FA used. Different aqueous formulations were prepared containing decreasing amount of FA (from 45.45% to 0%) an...
