A11.2.7 Secure disposal or re-use of equipment

According to ISO 27001:2013, it is not mandatory, but I would include that it can be recommendable because it is an evidence and can be requested by an auditor, and I think that it very easy to keep records when a secure disposal or reuse of equipment takes place. If you want to know the list of mandatory documents required by the standard (and not mandatory), please read this article "List of mandatory documents required by ISO 27001 (2013 revision)" : https://advisera.com/27001academy/knowledgebase/list-of-mandatory-documents-required-by-iso-27001-2013-revision/
