摘要： A method, apparatus and system for processing a composite waste source, such as e-waste, is disclosed. The composite waste source may comprise low-, moderate and high-melting point constituents, such as plastics, metals and ceramics. The composite waste source is heated to a first temperature zone, causing at least some of the low-melting point constituents to at least partially thermally transform. The composite waste source is subsequently heated to a second, higher, temperature zone, causing at least some of the moderate-melting point constituents to at least partially thermally transform. At least some of the at least partially thermally transformed constituents may be recovered. The method, apparatus and system disclosed may provide for the recovery and reuse of materials which would otherwise be sent to landfill or incinerated.
