Latest Patents

Niku-Paavola's latest patents include an **Intermediate product for preparation of lignin polymers and use thereof for production of wood materials**. This invention revolves around an innovative method of treating lignin derivatives with enzymes capable of oxidizing phenol, in the presence of oxidizing agents. The process stipulates that lignin derivatives undergo enzymatic treatment for over three hours or for more than ten minutes with air or oxygen introduced. The resulting lignin polymers are positioned as effective binding agents for wood materials.

Another significant patent is the **Process for preparing fiber boards**. This process details the manufacturing of fiber boards from lignocellulosic raw materials with at least 10 wt-% moisture content. The method involves separating an aqueous fraction from the fibers, which is then concentrated and enzymatically oxidized to polymerize solubilized wood materials. Lignin is added to the process to produce a robust binding agent before the mixture is shaped into boards and hardened.
