A method and a pelletizer press (2) for rendering a waste fraction (20) recyclable is disclosed. The method comprises the following steps: feeding metallic dust (20) into a basically cylindrical chamber (10) having a longitudinal axis (X) and an open end (28) and moving a first plunger (12) along the longitudinal axis (X) towards a base member (14) and hereby compressing the metallic dust (20) into a pellet (22) during a pressing process. The pelletizer press (2) comprises a pressing unit (24) comprising: a cylindrical chamber (10) having a longitudinal axis (X) and an open end (28); a first plunger (12) configured to be moved along the longitudinal axis (X); a base member (14) configured to be moved along the longitudinal axis (X) and/or to be maintained in a fixed position relative to the chamber (10); means for feeding a defined amount of metallic dust (20) into the chamber (10) and means for pressing the first plunger (12) towards the base member (14) and hereby compressing the metallic dust (20) into a pellet (22).
