When a body is cremated, if it has any metal parts, like a titanium hip, those metal parts are left behind. For years it was either buried in graves or sent to the dump. But a Dutch company, OrthoMetals, has a business that gathers those materials and processes them for industrial reuse, sending the proceeds to charity.
