Abstract

The low permeability Radiata pine (Pinus radiate D. Don) heartwood often mitigates against its use in high decay hazards. Microwave (MW) wood modification increases heartwood permeability and improves preservative distribution and uptake. The experimental study of MW log modification and impregnation allows the rational determination of MW processing parameters to achieve high standards of treatment with an estimate of the effect of MW treatment on timber quality, such as strength and check formation. The costs of MW heartwood round timber processing are acceptable to industry and provide good opportunities for conveyor belt treatment options.
