The security-relevance of the reverse vending machines

Reverse vending machines generate an electronic data set for each valid, compulsory-deposit one-way drinks packaging with which they are fed, this serving as a basis for deposit clearing in the DPG-System.

Since each of these raw data sets has a value of 25 cents, it must be ensured that

  • the recognition of DPG packagings by Reverse Vending Machines is reliable
  • That DPG packagings for which a data set has been generated have been reliably devalued
  • That packagings not entitled to a deposit are reliably rejected
  • That for each input DPG packaging no more than one data set can be prepared
  • That a counterfeiting of raw data sets can be fully excluded
  • That a duplication of raw data sets is not possible

Two-Stage Certification Procedure

The certification procedure foreseen for the licensing of DPG collection machines is a two-stages procedure:

Stage 1 " Preliminary Check (once only)

The licensing of a counting centre is undertaken by DPG following a successfully completed preliminary check by one of the DPG licenced certification bodies. The preliminary check consists of the following part-checks:

  • Document Check
    This is a check to ensure that all of the necessary specification documents and proofs in accordance with DPG certification regulations are available (e.g. operating instructions, process description, etc).

  • Appraisal
    The appraisal is undertaken on the basis of the DPG checklist for counting centres and covers all DPG specifications. It consists of an "on-site" appraisal of the company-internal infrastructure by the experts(s) / auditor(s) of the certification body. After successful examination, a report on the certification is prepared and, following a Stage-1 Certificate, issued on the preliminary check. This is the precondition for a DPG licence.

  • Generation of raw data sets
    Apart from checking the mechanical components of the counting centres, a check on the IT side also forms a part of the certification. 6 months after passing the preliminary check (stage 1), at the latest, the first certification audit (stage 2) must be completed with the issuing of a certificate.

Stage 2 " Initial Certification

The first certification audit consists of an "on-site" appraisal by the certification body of the company-internal infrastructure. After successful initial certification a report on the certification is prepared and is issued as a Stage-2 Certificate.

After satisfying the initial certification or repeat certification, a certificate will be issued, this being valid for a maximum of 18 months, subject to the precondition that every 12 months a renewed repeat certification is undertaken on the basis of the DPG specifications valid at the time.


Deposit Clearing in the DPG deposit scheme operates on the basis of electronic raw data sets that can also be generated at the subsequent automatic recording in the counting centre. For each collected DPG packaging exactly one signed, non-copiable electronic data set is generated.

Collectors who have no reverse vending machines for the collection of one-way drinks packaging in their shops can commission counting centres with the counting and recording of their empty one-way drinks packagings.

A counting centre is a certified facility that makes use of Industrial Reverse Vending Machines and/or Counting Tables of DPG packagings from collection points, reads them, devalues them and signs raw data sets as a basis for deposit clearing in the DPG-System.

Companies that want to operate counting centres must conclude a licensing agreement with DPG and have the respective location of the counting centre certified by a DPG licenced certification body.

Within the framework of a two-stage certification process operators of Counting Centres must show that, in connection with the collection of DPG packagings, they work properly and generate valid raw data sets.
