GDPR and paper waste: What companies should consider for confidential documents

Confidential printouts, customer data, and internal documents do not belong in an open wastebasket. Data protection in the office often begins precisely where paper is disposed of.

Even in a digital office, paper documents are created daily. Invoices, offers, notes, misprints, applications, or personnel documents can contain personal or confidential information. If disposed of incorrectly, an avoidable data protection risk arises.

Short answer

Documents containing personal, confidential, or business-critical information should not be put in general paper waste. Companies should use clear collection points, responsibilities, and shredders with the appropriate security level.

Why paper waste is a data protection issue

Paper waste is often underestimated in the office. A printed offer, a customer list, a misprint, or an old delivery note can contain information not intended for unauthorized persons. Therefore, disposal should not be an afterthought.

  • Customer data can be on printouts
  • Invoices and offers often contain sensitive information
  • Personnel documents must not be disposed of openly
  • Internal notes can contain business-critical details
  • Misprints are often thrown away too quickly

Which documents do not belong in the wastebasket?

Not every piece of paper is automatically critical. However, as soon as personal, confidential, or internal information is involved, secure destruction should be considered.

Document Example Recommendation
Customer data Offers, delivery notes, lists destroy
Personnel documents Applications, working hours, salary destroy securely
Internal documents Prices, strategies, notes destroy depending on protection needs
Misprints incorrectly printed invoices do not throw away openly

Shredding instead of an open wastebasket

A document shredder is not just an office device, but part of the data protection organization. It is important that employees know which documents need to be shredded and where they can dispose of them securely.

Frequent Questions

May documents with customer data be put in the paper waste?

No, confidential documents with customer data should not end up openly in the paper waste. Secure document shredding with the appropriate security level is advisable.

Which documents should companies shred?

These include customer data, personnel documents, internal price lists, offers, invoices, notes, misprints, and documents containing confidential information.

Which security level is appropriate?

For many confidential office documents, P-4 is a sensible starting point. For particularly sensitive data, P-5 may be more suitable.
