Our climate impact
TOMRA Collection’s avoided emissions are calculated using a methodology developed together with independent sustainability experts, Eunomia, and aligned with recognised international guidance on avoided emissions from the World Business Council for Sustainable Development (WBCSD).¹
Avoided emissions describe the greenhouse gas emissions that are prevented because TOMRA’s solutions are in use. We calculate them by comparing two situations: one where TOMRA Collection’s reverse vending and, in some markets, material handling solutions are in place, and one where they are not. The difference between these two situations shows the emissions that are avoided thanks to TOMRA’s technology and services.¹
The calculation is based on real, annual data on the number of empty drink containers returned through TOMRA reverse vending machines. We use a year‑by‑year approach rather than long‑term projections, which helps keep the results conservative and transparent.¹
The comparison depends on TOMRA Collection’s role in each market. In markets where TOMRA provides reverse vending machines, we compare today’s deposit return system with a system that works without the added convenience, automation and compaction those machines provide. In markets where TOMRA also runs material handling operations, we compare today’s system with a situation where those services are not available and the deposit return system would not work effectively.²
Reverse vending machines make returning bottles and cans easier, faster and more convenient for people. This improved recycling experience leads to higher return rates compared with systems that rely on manual or less accessible collection methods.³
The avoided emissions come from three main effects. First, higher return rates mean more bottles and cans are recycled. This reduces emissions by avoiding the need to make the same materials from scratch and by keeping material out of incineration and landfill.² Second, containers collected through deposit return systems are cleaner and easier to sort, which means less energy is needed during sorting.² Third, reverse vending machines compact containers at the point of return, so fewer transport trips are needed to move the same amount of material.²
Data on return rates and deposit return system performance is based on country‑level information published by Reloop and other public sources.⁴ Assumptions about differences between systems with and without reverse vending machines are informed by evidence showing that deposit systems with convenient return options consistently achieve higher return rates.³
Emissions factors for recycled materials are based on established industry data and peer‑reviewed studies and are consolidated within Eunomia’s life‑cycle assessment models.⁵ ⁶ ⁷ ⁸ ⁹ ¹⁰ ¹¹
The same assumptions are applied consistently to both the current situation and the comparison case.¹ The results are sensitive to return rates and system design, so conservative assumptions are used and key limitations are documented. Avoided emissions reflect the wider climate impact of TOMRA’s solutions and do not reduce the company’s reported greenhouse gas emissions. Avoided emissions are reported separately from TOMRA’s own emissions and are not used to claim carbon neutrality or net zero. ¹

Reverse vending machines and sustainability
The business landscape is changing, but we don’t see this as a bad thing. We see it as an opportunity. Our strategy is simple: Do more of what we do best, while reducing the negative impacts our operations have on the environment. After more than half a century spent working in resource productivity, striving towards a world without waste, we see that the changes required of us already align with our values. We welcome them!
More of what we do best
Less environmental impact
Product sustainability starts with design
Our life cycle assessment (LCA) approach considers the entire life cycle of our products, including the production-, use- and end-of-life phases. The EF 3.0 method¹ is used to calculate the environmental impact while SimaPro and Ecochain Mobius are used to perform the calculations and analyze the results.
The production phases are modelled by grouping individual components from the BOM in specific
material categories, which are then connected to their respective production impacts using
ecoinvent².
For the assembly phase, data on energy consumption and waste generation of similar products is gathered for use in analysis.
The use phase is covered through data on energy consumption (both idle and active mode),
information on maintenance visits, and expected repair needs. TOMRA Collection typically uses
Germany as a proxy market in LCA calculations, as the market plays a major role in TOMRA's business
and offers more conversative estimates of energy-related emissions than European averages, while
providing a specific geography for calculating transport distances.
The end-of-life impacts are modelled using the average recycling rates given in a relevant contemporary source, for example JRC (2020)³ has been used previously.
The cut-off approach was used to divide the environmental loads from recycling between product life cycles.
If the life of the material is ending (for example in landfill or incineration), then the impact is allocated
to the product and included in the results. Whereas, if the life of the material involves being sent for
recycling, then the impact is not allocated to the product, and is excluded from the results.

TOMRA Retility
And that’s what it’s all about!
TOMRA Retility targets
Repurposing existing parts and components from retired products, and ensuring that nothing goes to waste.
For example, using recycled and recyclable materials in the production of products and replacement parts.
Through refurbishment, repair, remanufacture, and smart innovation, we improve the durability and lifespan of our products.
Taking responsibility for retired TOMRA products and waste parts created during service
Despite the huge positive impact that TOMRA reverse vending machines enable, when those machines reach their end of life, it’s our responsibility to ensure that their disposal leads to as little negative impact as possible.
Recycling waste polymers
One way for us to reduce our footprint is to make our products more recyclable when they are retired and to use more recycled material in our products.
