With a total of 3 patents, his work focuses on innovative processes that enhance the quality and efficiency of lignocellulosic materials.

Latest Patents

One of his latest patents is a process for producing fibrous material from wood. This process involves preparing a solution of chemicals containing less than 25% of sulphite, based on the oven-dry amount of the lignocellulosic raw material. The method includes mixing this solution with wood and heating it to a temperature above room temperature. The process offers two alternatives: either removing the free-flowing solution of chemicals and digesting the wood in the vapor phase or digesting the wood in the liquid phase while separating the solution. Another significant invention is a wood-based lignocellulosic fibrous material that boasts a tearing length of more than 8 km at 15° SR and a lignin content of at least 15% for coniferous wood. For deciduous wood, it has a tearing length of more than 5.0 km at 20° SR and a lignin content of at least 12%.
