What Is DESUP and How Is It Prepared?

BLN Çevre Teknolojileri · 23 October 2026

In brief: DESUP (deposit field implementation plan) is the document in which an authorised DRS operator (DSYS operator) commits to the Turkish Environment Agency (TÜÇA) how it will operate in the field. Field operations cannot commence without approval. Throughout the national integration period (UES) (July 2026 – June 2028), province-level DESUP approval is a prerequisite for the operator's revenue model.

Why is DESUP critical?

DESUP is the document that translates operator authorisation into field operations. An incomplete or inconsistent plan enters a revision cycle and can delay the application process by months. More importantly, the capacity declared in the plan becomes the operator's scorecard during the operational phase: TÜÇA compares actual field collection against this declaration.

Guidelines specify what the plan must contain, but largely leave how to prepare it to the operator. Aspects such as the format of site contracts and the relationship between capacity declarations and actual collection remain open to interpretation.

What does a DESUP include?

• Operating region: target provinces, population and consumption assumptions.
• Return point network: reverse vending machine (RVM, or DİM) and manual return point (MİN) locations, HoReCa channel and site contracting infrastructure.
• Daily capacity declaration: the volume the operator commits to collect and verify.
• Collection and transport plan: vehicles, routes, collection frequency.
• Counting and verification infrastructure: counting centres (SDM) and counting and verification lines (SDH) where containers will be counted and verified.
• Equipment and data integration: planning of RVMs and handheld terminals, integration with the Deposit Information Management System (DBYS).

Preparation steps

1. Current state analysis: verification of operating regions, target provinces and capacity assumptions.
2. Return network planning: identification of candidate return points and preparation of site contracts.
3. Capacity and logistics: structuring the daily capacity declaration alongside the collection and transport plan.
4. Equipment plan: defining RVM and handheld terminal requirements alongside DBYS integration requirements. RVMs must be selected from registered models of authorised manufacturers listed in DBYS.
5. Application dossier: preparing the dossier, submitting it to TÜÇA and managing the revision process.
6. First 30 days post-approval: deploying the plan to the field; opening the initial return points and establishing the collection rhythm.

Duration varies according to the number of provinces and level of readiness. In BLN's experience, a typical DESUP process takes 6–8 weeks up to submission of the application dossier.

Common pitfalls

• Unrealistic capacity declarations: overdeclaring capacity to strengthen the application results in an unachievable commitment during operations.
• Late execution of site contracts: locations mapped without signed contracts create gaps between the plan and field reality.
• Planning logistics in isolation from capacity: collection frequencies and vehicle planning must be calculated directly from declared volumes.
• Leaving counting and verification infrastructure to the last minute: counting centres (SDM) represent one of the most capital-intensive elements of the system; site location and sizing must be clarified from the outset.

Post-approval: system performance management

DESUP approval is not the end, but the beginning. The most common issue during operations is divergence between plan figures and field realities. Regular monitoring of return point performance, variances between declared and actual collection, and TÜÇA reporting makes these gaps visible prior to audits.

Frequently asked questions

What is DESUP?

DESUP (deposit field implementation plan) is the document in which a DSYS operator commits to TÜÇA how it will operate in the field. Field operations cannot commence without approval.

What does a DESUP include?

Operating regions and capacity assumptions, return point network and site contracts, daily capacity declarations, collection and transport plans, counting and verification infrastructure, RVMs, handheld terminals, and DBYS integration.

How long does it take to prepare a DESUP?

It varies depending on the number of provinces and the level of readiness. In BLN's experience, a typical DESUP process takes 6–8 weeks up to submission of the application dossier.

What happens after DESUP approval?

Approval is not the end, but the beginning. Actual field collection against declared capacity must be monitored; any variance between declared and actual collection must be managed before TÜÇA audits.
