A continuous method is provided for recycling a metal/organic laminate comprising metal, such as aluminium, laminated with an organic material, the method comprising: providing a reactor ( 1 ) comprising a first chamber ( 2 ) having a first rotary stirrer ( 4 ) and a second chamber ( 3 ) having a second rotary stirrer ( 5 ), each chamber ( 2, 3 ) containing a bed of particulate microwave absorbing material; introducing laminate and additional particulate microwave absorbing material into the first chamber ( 2 ) via an inlet ( 6 ); under a reducing or inert atmosphere stirring the mixture of particulate microwave absorbing material and laminate in the first chamber ( 2 ) using the first rotary stirrer ( 3 ) and applying microwave energy in the first chamber ( 2 ) to heat the particulate microwave absorbing material to a temperature sufficient to pyrolyse organic material in the laminate; transferring a portion of the mixture in the first chamber ( 2 ) to the second chamber ( 3 ); stirring the mixture in the second chamber ( 3 ) using the second rotary stirrer ( 5 ) and applying microwave energy in the second chamber ( 3 ) to heat the particulate microwave absorbing material to a temperature sufficient to pyrolyse organic material remaining in the laminate, whereby laminate or delaminated metal migrates towards and floats on the upper surface of the mixture in the second chamber ( 3 ), said second rotary stirrer ( 5 ) rotating in a horizontal plane and being so configured as to fluidise the mixture such that the upper surface of the fluidised mixture has a radial profile that biases laminate or delaminated metal floating on the fluidised mixture to migrate radially outwards; transferring a portion of the mixture in the second chamber ( 3 ) to an exit ( 7 ) from the reactor ( 1 ); and recovering metal from the exit ( 7 ). Also provided is a reactor ( 1 ) for recycling a metal/organic laminate comprising metal, such as aluminium, laminated with an organic material.
