Forintek Canada Corp., as a scientific organization, was commissioned by the Task Force on Pasteurization of Softwood Lumber to lead a research initiative to examine heat treatment (pasteurization) as an alternative to kiln drying for the eradication of pinewood nematode (PWN) and a sawyer beetle (Monochamus) from green, unseasoned softwood lumber. The project had a laboratory component (Phase I) where statistical analysis for confidence and reliability could be used to determine a mortality curve for PWN on wood samples. Concurrent studies (Phase II) using laboratory dry kilns were done to measure heating times for a wide range of wood species and selected wood species of different thicknesses. From the first two Phases of the project a demonstration (Phase III) of the successful application of pasteurization to green lumber was then arranged at three sawmill sites across Canada, with verification by scientists of the European Economic Community (EC) team. Finally, Phase IV in the project evaluated some alternate technologies to pasteurization.
