Abstract

A process for recycling lignocellulosic fibers from a fiberboard () comprising compressed lignocellulosic fibers bonded together by a binding agent. The process comprises the steps of: —disintegrating () the fiberboard () to provide fiberboard pieces (); —steaming () the fiberboard pieces () to decompress and release the lignocellulosic fibers by hydrating them, as well as hydrolyzing the binding agent; —releasing the overpressure; —removing excess water vapor to provide portions () comprising released lignocellulosic fibers; and —separating () the lignocellulosic fibers in the portions () comprising released lignocellulosic fibers to provide recycled lignocellulosic fibers ().
