Abstract

The present invention relates to a method for producing fiberboard or glue powder for fiberboard production, comprising - supplying (11) lignocellulosic material (LM) to a reactor (1), - treating (12) the lignocellulosic material (LM) in the reactor (1), - discharging (13) the lignocellulosic material (LM) from the reactor (1) through an outfeed unit (2) to a pressure drop unit (3) that comprises a receiving portion (32) held at a lower pressure for causing steam explosion of the lignocellulosic material (LM) to create steam exploded fibers, and drying and pressing the steam exploded fibers to fiberboard or alternatively providing the steam exploded fibers as a glue powder. The invention also relates to a manufacturing arrangement.
