This dissertation investigates new approaches to the material recovery and utilization of used wood-based panels and spruce bark. The research focuses on developing and optimizing a process in which used particleboards and fiberboards undergo thermohydrolytic treatment, with the resulting hydrolysates subsequently used for spruce bark extraction. The objective is to obtain tannin-rich extracts suitable for use as adhesives or adhesive additives in wood-based panel production. Different extraction processes are compared, and the chemical and technological properties of the recovered materials are examined. The study also evaluates the potential of spruce bark extracts to partially replace synthetic adhesives in particleboard manufacturing. The findings contribute to the development of alternative adhesive systems and more resource-efficient utilization of industrial wood residues.
