»ReNew«: Reuse and recycling of wood waste

The pressure on wood as a resource is increasing. The substitution of fresh wood with waste wood is therefore highly relevant both economically and ecologically. However, for legal and technical reasons, only smal fraction of the wast wood can be recyceled. Constantly changing framework conditions, for example prices for oil and wood due to strong market movements, make it difficult to plan investments in plants and systems for waste wood recycling. However, there is strong political support for the cascading use of waste wood.

The »ReNew« project contributes to the cascading use of waste wood by improving the technical processes and economic efficiency of waste wood processing and making it more calculable for the companies involved. In particular, higher-value products are developed from waste wood, waste wood components that could not previously be used as materials are used for innovative products and the data generated during the necessary sorting is used for process analysis.

We have been developing X-ray technology for sensor-based sorting for more than 10 years. We research questions from industry and science and deliver holistic solutions from sensor development and image processing to prototype construction. The development of multi-energy X-ray evaluation in the areas of recycling, food safety and mining is being accelerated.
