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...

Wood Hydrophobic Modification by Mixed Wax Emulsions
2018 - IRG/WP 18-40839
An environmental-friendly, economical and facile method to construct hydrophobic system for improving wood repellency was applied in this study. Using paraffin wax and carnauba mixed wax O/W emulsions can simultaneously fabricate continuous wax films and rough structures in wood internal and external surface under appropriate heat treatment. In the study, single and mixed wax emulsions of 4% solid...

Surface treatment of cross-laminated timber to improve water repellency and UV resistance
2024 - IRG/WP 24-20716
Cross-laminated timber (CLT) has emerged as a revolutionary building material, offering a sustainable alternative to traditional construction methods. By layering and bonding multiple layers of wood at right angles, CLT creates a robust and versatile structural element capable of supporting significant loads while promoting eco-friendliness and design flexibility. However, despite its numerous adv...
