A certificate of destruction/recycling is a document that a company should receive from a third-party vendor to verify that the decommissioned hardware has been destroyed or recycled in a secure manner and in compliance with environmental and data protection regulations. This document typically includes details such as the method of destruction, date and time of destruction, and the specific items destroyed. It takes responsibility for the secure disposal process, thus protecting the company from potential data breaches or non-compliance fines.
