…In Germany and Europe, new concepts are therefore being discussed for more responsible and efficient industrial use of wood, but resources are still limited. Researchers at the Technical University of Munich (TUM) are using data from a European research project to analyze the potential efficiency of multiple use between harvesting and combustion of wood. Does the cascading use of wood really lead to increased resource efficiency? For example, if the raw wood is first used to make construction elements, then slats for a table, and finally chipped and turned into chipboard before being burned for energy in a power plant? Michael Risse and Professors Gabriele Weber-Blaschke and Klaus Richter from the Chair of Wood Science at TUM set out to find suitable assessment methods. …The result: In cascading use, the wood is utilized significantly more efficiently at a rate of 46 percent, compared to single use at 21 percent.
