A method and unit for recycling a bituminous membrane provided with at least one reinforcement. Said membrane is broken into pieces which are introduced into a recycling unit provided with a first rotor, accommodated in a first stator, where they are heated and crushed. The pieces are transported to a chamber which is defined by an outer partition of the first rotor and a recess fitted in a counter element mounted on the stator, where they are pulverized. The pulverized pieces are then drained off from the chamber along the outer partition of the rotor.
