Particles from Residue Wood-Based Materials from Door Production as an Alternative Raw Material for Production of Particleboard

Problems with the availability of particleboards are a challenge for constructors and production companies that use this material in the technology of their products. During the production process of technical door leaves, a significant amount of wood-based panel residues is created, which is a large base of potential raw material on an annual basis. Given the conceptual link between circular economy (CE) activities, resources, and waste management, efforts should be made to process and reuse them to produce new particleboards. The aim of the study was to determine the physical and hygienic properties of particles obtained from the grinding of lignocellulosic composites used in production. It was found that in terms of dimensions, density as well as formaldehyde content, they have the potential to be an alternative source of raw material for the production of particleboards. However, selecting the type of materials should be carried out, and in the future, the hygienic properties of the manufactured particleboards should be controlled.
