Laboratory termite testing of copper boron tebuconazole
2000 - IRG/WP 00-20192
The American Wood Preservers' Association laboratory choice and no choice termite test (AWPA E1-97) was performed on a formulation of copper azole, which is comprised of copper, boric acid, and tebuconazole. The formulation tested has a ratio of copper:boric acid:tebuconazole of 25:25:1. So as to examine the impact of leaching, the southern yellow pine wafers were treated with and without...

The effectiveness of three tributyltin compounds in beech against soft rot fungi using a soil-bed technique: A preliminary report
1986 - IRG/WP 3390
The effectiveness, towards soft rot fungi, of bis (tributyltin) oxide, tributyltin ethanesulphonate (TBTES) and benzyltributylammonium tributyldichlorostannate in both leached and unleached beech stakes is compared to that of a CCA preservative (Tanalith CT 106), using a soilbed technique. In addition, the effect of test solvent (water or toluene) on the performance of TBTES is evaluated. Total ti...

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...
