To unlock the full potential of waste fibreboard and wood, EcoReFibre is adapting a process commonly used in the pulp and paper industry: the thermo-mechanical pulping (TMP). In this method woodchips are softened with heat and moisture before mechanically refined into fibres.

In Demo C, this process is modified (mTMP) to work with recycled materials. Fibreboard is first shredded and threaten with heat and water to loosen the glue that binds the fibres together. It is then refined under controlled pressure, temperature and cooking time to release fibres while preserving their quality. Solid wood waste follows similar route: chipped, steamed, and refined into fibres adapted for new products such as fibreboard or insulation. By fine-tuning the process, the project demonstrates how waste materials can be transformed into high quality fibres with improved energy efficiency, ready for reuse in new applications.
