**4. Conclusions**

The properties of boards based on lignocellulose particles, referred to as chips, strips, or chopped strands, depend on several technological factors that have been known for years. However, there is still a need for research to refine specific solutions, especially when trying to add new materials to the production of boards. Based on the result, the following conclusions were drawn:
