Erasure certificates and the evidence chain — why serials count
Without a serial the certificate is useless to internal audit. The Datenschutzbehörde does not buy bulk PDFs.

One line per drive
Austrian audits — Vienna banks, Land administrations, hospital groups — check line by line. A bulk certificate without serials does not close the DSG file.
RecyclicTech issues an erasure certificate per drive or serial. Method: NIST SP 800-88. The chain runs from the dock to processing in Rădăuți — declared.
Audit-ready, not brochure-ready
An unbroken chain means: who took it, when, which asset, which method, where next. A brochure that says “GDPR compliant” without a method is worthless to the Authority.
The itemised asset report sits in the same file. Internal audit wants the line, not the slogan.
