Microwave (MW) wood modification provides an increase in wood permeability for liquids and gases and reduces internal stresses in timber. As a pre-conditioning process, it enhances existing processes and facilitates the development of entirely new processes and product options for wood. MW wood modification allows: improved timber preservative treatment, fast lumber drying, stress relief in timber and manufacturing of the new material "Vintorg" . New high power MW installations operating at 0.922 and 2.45 GHz have been designed and built for different applications. A microwave plant with a maximum output of 300 kW and a processing capacity of 10,000 m3/year will be used for processing logs u..
