Research Projects (relevant to Action)

Wood material from differently managed forests: properties, measurement and modelling

The purpose of the project is to gather scientific and practical information about how sustainable but economically profitable forestry effect wood raw-material properties. Special emphasis is on different-aged forests. Research is also concentrated on very intensive management and its effect on wood raw material. Data will be used in order to create models how forest management effects wood properties and to improve existing wood property models. Response of wood raw material to electromagnetic radiation will be studied and an electromagnetic model of wood will be developed. Fast methods make possible on-line measurements and sorting of wood raw material for different end-uses. The purpose is also to study the possibility to use industrial birch extracts to increase decay resistance of wood and wound healing properties of spruce resin.
