Around 8 to 10 million metric tonnes of waste wood accrue in Germany every year. A good 80 percent of this is used directly for energy, i.e. incinerated. In order to make more efficient use of wood as a resource, it is necessary for significantly more waste wood to be materially re-used (material recycling). One obstacle is the fact that up to now, considerable effort has been required in order to determine possible contamination. A significant simplification is being developed within a project led by the University of Greifswald in collaboration with the Fraunhofer WKI and industrial companies: the optimization of “X-ray fluorescence analysis (XRF)” for the sample type waste wood. The new analysis method should be quick and easy to use for all parties involved in the waste-wood value chain – for example recycling companies, wood-based material manufacturers and authorities.
