Hero Block A Bottle’s Journey

From the production line to the supermarket shelf, the recycling machine and back again

Every PET bottle that passes through a TOMRA reverse vending machine has a story. This is that story — told in six chapters.

Rich Text Block Chapter 1: Born from Oil

It begins with crude oil. PET (polyethylene terephthalate) is a thermoplastic polymer derived from petroleum. The manufacturing process is energy-intensive: producing one kilogram of virgin PET requires approximately 77 megajoules of energy. A standard 500ml PET water bottle weighs around 18 grams. The energy embedded in it before the consumer even picks it up is measurable and significant — this is the energy that is lost when a bottle ends up in general waste instead of being recycled.

Rich Text Block Chapter 2: Filled and Sold

The bottle travels from the packaging plant to a beverage filling facility. It is washed, filled, capped, labelled and packed into cases for distribution. A barcode is applied — the same barcode that, in a deposit return system, will later identify the container and trigger a refund.

The bottle reaches a retailer’s shelf. A consumer purchases it. In a country with a deposit return scheme, they have paid a small deposit — typically 10 to 25 cents — on top of the purchase price. That deposit is the key to what comes next.

Rich Text Block Chapter 3: Consumed and Returned

The bottle is opened. The beverage is consumed. The consumer inserts the empty bottle into a TOMRA reverse vending machine. In under four seconds, the machine reads the barcode, verifies the container against the national DRS product register, compacts and stores the bottle, and issues a refund — as a voucher, digital credit or cash.

Rich Text Block Chapter 4: Sorted and Recovered

The compacted material is collected by a logistics operator and transported to a material recovery facility. Here, bales of PET are processed — shredded, washed and extruded into high-quality recycled PET flake or pellet (rPET).

Because the material was collected through a DRS — rather than mixed household recycling — it is exceptionally clean and consistent. This rPET commands a premium price in the market and can be used in food-grade applications: new bottles, food packaging, fibres. The carbon footprint of recycled PET is approximately 70% lower than that of virgin PET.

Rich Text Block Chapter 5: Born Again

The rPET pellet becomes a new bottle. That bottle is filled. Sold. Consumed. Returned. The circle closes. In the best-performing DRS markets — like Norway, where TOMRA operates the national deposit return system — a PET bottle can complete this cycle multiple times before the polymer degrades.

This is not a utopian vision. It is the operational reality in Norway, Sweden, Germany, Finland, Estonia and a growing number of markets worldwide. The technology exists. The systems work. The question is how quickly the rest of the world will follow.
