How Barcode Scanning Works in Tomra Reverse Vending Machines

TOMRA Reverse Vending Machines scan barcodes on bottles and cans, verify them against a database, and accept valid items for recycling, providing instant refunds or rewards while preventing fraud.

Overview

When you drop a container into a Tomra RVM the machine identifies it using barcode scanning, validates eligibility, assigns value, sorts, compacts and credits your refund — automatically and quickly. The animated visuals beside each step show the core action in miniature.

Step 1: Scanning the Barcode

When a container enters the Tomra RVM the barcode is read immediately. It uses camera-based or laser scanners designed to capture codes while items are moving.

Cameras or lasers: either technology can be used — both are precise and handle movement well.

360° coverage: some models have all-around cameras so you don’t need to orient the item.

Instant image processing: an on-board processor decodes UPC/EAN data on the spot.

Robust to noise: algorithms correct for reflections, shadows and slightly damaged labels.

Fallback sensors: if a barcode is unreadable, shape/weight/material sensors can act as backup.

Step 2: Validating the Barcode

After decoding, the barcode is checked against an operator-maintained database to determine whether the container is eligible for credit.

Database check: the decoded code is matched with a maintained list of eligible containers.

Always updated: operators update the database remotely to match current deposit-return rules.

Yes / No decision: match = accept; no match = reject immediately.

Anti-fraud: validation prevents lookalike or fake containers from being credited.

Step 3: Determining Container Type and Value

The barcode contains metadata that helps the RVM determine material, size and associated refund value — ensuring accurate crediting.

Material recognition: identifies plastic, aluminum or glass from product data.

Size confirmation: barcode links to the container’s size so the correct deposit is applied.

Automatic refund: the correct deposit is assigned instantly based on material and size.

Cross-checks: weight or shape sensors may verify the barcode’s claim.

Step 4: Processing and Sorting Containers

Approved containers are routed, logged and often compacted so storage, transport and recycling are efficient and secure.

Sorting pathways: plastics, cans and glass are routed to separate bins.

Compaction: bottles are compressed and cans flattened to save space and reduce handling costs.

Fraud prevention: compaction and logging reduce opportunities for tampering.

Accurate logging: each accepted item is tracked for reconciliation and reporting.

Step 5: Linking Barcodes to Rewards

Once items are accepted and logged, refunds or rewards are issued. Tomra supports printed vouchers, loyalty accounts, or app-based credits.

Multiple options: print a voucher, credit a loyalty account, or push value to an app.

Personalization: apps can show recycling stats, history, or let you donate refunds.

Instant credit: every accepted container is recorded and added to your refund in real time.
