Zusammenfassung:The invention provides a method for producing secondary aluminium (50), the method comprising providing aluminium-containing scrap material (35), providing carbon-containing scrap material (20) from an electrolysis cell (10) for the production of primary aluminium (15), introducing the aluminium-containing scrap material (20) into a rotary furnace (40), processing the carbon-containing scrap material (20) to produce a scrap fuel (55), and melting the aluminium-containing scrap material (35) in the rotary furnace (40) using energy generated by burning the scrap fuel (55) such as to produce secondary aluminium (50).
