The disclosure relates to a method for the production of wood fiberboards such as MDF boards.

Method for producing wood fiberboards

A method of increasing the throughput and/or decreasing the energy usage of a pulping process includes the steps of providing a plurality of lignocellulosic chips, providing a refining composition, applying the refining composition to the plurality of lignocellulosic chips, and mechanically refining the plurality of lignocellulosic chips to form pulp. The refining composition includes water and a lubricating additive including the reaction product of a sugar and an alcohol. The step of applying the refining composition to the lignocellulosic chips is conducted less than 5 minutes prior to, or concurrently with, the step of mechanically refining the wood chips to form pulp.
