Latest Patents

Suortamo holds a patent for a process that produces mechanical pulp suitable for paper or cardboard making. The patent describes a method for the production of mechanical or chemi-mechanical pulp as raw material. This innovative process involves fibrillating the pulp and bleaching it under alkaline conditions. The method also includes screening the pulp to separate rejects from accepts, ensuring that a maximum of approximately 60% of the total pulp is classified as reject. The reject is bleached separately from the accept, and after bleaching, the two are remixed. This approach not only increases the strength of the pulp but also reduces the energy required for refining, benefiting both the reject and the final mechanical pulp.
