Remanufacturing is the process of disassembly and recovery at the module level and, eventually, at the component level. It requires the repair or replacement of worn out or obsolete components and modules. Parts subject to degradation affecting the performance or the expected life of the whole are replaced. See an example of a professional automotive electronics remanufacturing flow. Remanufacturing is a form of a product recovery process which differs from other recovery processes in its completeness: a remanufactured machine should match the same customer expectation as new machines.
