Forest product management should follow the principles and objectives of sustainable development. Therefore the use of wood from plantations must be emphasized. The plywood industry in Taiwan, having accepted this concept, is increasingly concerned with advancing manufacturing technologies to meet the requirements for wood resources. This article presents test results obtained from a study on the technological feasibility of plywood manufacturing using domestic coniferous plantation wood. Rotary-cut veneer from domestic wood of planted Japanese cedar (Cryptomeria japonica) and Taiwania (Taiwania cryptomerioids) was not comparable in quality to that from imported radiata pine. Studying on veneer cutting methods of domestic wood species would help improve the veneer quality and is recommended accordingly. With the view to increase cutting efficiency and veneer grades, a significant effect may result from enhancing the silvicultural practices of tree planting and growth. Plywood may be made from assembled wood veneers of various species. The veneers used in this study were found to be compatible for gluing. The properties of the plywood panel produced, varied with veneer quality and thus the wood species of concern.
