The most significant sustainability impacts often arise not only from how products are made, but from how they perform throughout their lifecycle. At Nynas, we aim to reduce environmental impact and enhance performance across the full value chain. From raw material sourcing and production to use phase and end of life, our products are designed to improve efficiency, extend service life, and support more circular solutions.
1. Raw materials
Nynas uses hydrocarbon feedstocks as input materials and focuses on transforming them into durable, value-adding products designed for long service life. In general, these products do not generate CO₂ emissions during their use phase.
We continuously develop ways to increase the use of renewable and circular raw materials without compromising technical performance. For transformer oils, NYTRO® RR 900X uses re-refined transformer oils as feedstock while NYTRO BIO 300X is produced using renewable feedstock – just like our tyre and rubber oil NYTEX® BIO 6200.
By incorporating biogenic feedstock into the production process, our EVO portfolio achieves up to 25% lower Product Carbon Footprint (PCF) compared to Nynas’ legacy grades, without any alteration of the trusted product characteristics.
2. Production
Nynas’ production is designed to optimise product quality, efficiency and resource use. Advanced catalytic hydrotreatment, biomass-based steam generation and process optimisation help reduce environmental impact while maintaining high-performance product characteristics.
We work continuously to reduce the climate impact associated with energy use across our production, operations, and transportation. This includes increasing the share of renewable energy, phasing out carbon-intensive energy sources, and exploring emerging technologies that support long‑term decarbonisation.
The transition from combustion‑based energy to electricity, biofuels and waste‑heat recovery in our production has contributed to annual reductions of 35,000–60,000 tonnes of CO2. At the Nynäshamn manufacturing site, residual heat recovery corresponds to approximately 35 GWh per year, enough to heat around 1,750 homes – an example of industrial symbiosis where unavoidable process heat is utilised as a community resource.
3. Use phase
For many applications, the most significant sustainability impact occurs during the use phase. An independent study comparing selected Nynas products with common market alternatives estimated substantial lifecycle benefits linked to improved efficiency and performance – corresponding to approximately 740,000 tonnes of avoided CO₂ emissions, equivalent to 1.7 million barrels of oil.
- Transformer oils designed for efficient cooling help reduce energy losses and support long service life in critical power infrastructure.
- Studies indicate that NYTEX® 4700 can contribute to approximately 5% lower tyre rolling resistance, helping reduce fuel consumption and extend EV range while maintaining critical safety properties.
- Polymer-modified binders improve elasticity and resistance to cracking, helping extend pavement life and reduce maintenance needs.
- In applications such as lubricating greases and adhesives, Nynas products can enable lower process temperatures and lower material intensity.
4. End of life
Nynas aims to increase circularity across its product portfolio by enabling reuse, regeneration, and resource efficiency at end of life. Hydrocarbon-based transformer oils support circular product flows through re-refining, where used oils can be restored to as-new quality using Nynas' hydrogenation technology.
Bitumen can be reused repeatedly, and Nynas promotes higher reuse rates through solutions such as NYGEN® 910, a rejuvenator that restores binder performance and supports increased incorporation of reclaimed asphalt pavement (RAP).
