Giving old solvents a new life

By combining our expertise and utilising 200-year-old distillation technology, Ragn-Sells and environmental technology company Vilokan are transforming solvent production. With our new Solvent Recycling Solutions facility, we produce recycled solvents with up to 81% lower climate emissions than equivalent virgin products on the market.

– With Solvent Recycling Solutions, we address two issues at once. One, we make use of a resource that is usually incinerated. Two, we replace fossil-based, emissions- heavy solvents with circular alternatives. Closing the loop on solvents significantly reduces climate emissions at both ends of the process, says Erik Gustafsson, Business Project Manager at Ragn-Sells Treatment & Detox Sweden.

The story of Solvent Recycling Solutions (SRS) began in 2019, when Erik was tasked with exploring the business potential of solvent recycling. In addition to drawing on expertise from both the Recycling and Treatment & Detox business areas, environmental technology company Vilokan was soon brought on board. With extensive experience of working with solvents, Vilokan provided the technical and market insights needed to design a comprehensive solution.

– If we are to accelerate the circular transition, collaboration is essential. SRS is a prime example of how two companies can join forces to develop a new model of industrial cooperation. In addition to radically reducing the climate footprint of solvent production, I hope that our partnership encourages others to follow suit, says Lars Rosell, Deputy CEO of Vilokan Group. 

"Like metals, solvents can be recycled indefinitely, making them exceptionally well-suited to circular flows."

The SRS facility, which opened in Sweden in September 2025, can process up to 20,000 tonnes of used solvents each year. The solvents, including acetone, ethanol, methanol, and glycol, are purified using an advanced form of traditional distillation technology, after which they can be used in products like cleaning agents, disinfectants, and washer fluid.

– The interest in our products has been enormous. This comes both from a climate perspective, as companies seek to source more sustainable solvents, and from a resilience perspective, as they want to avoid dependence on fossil raw materials and long global supply chains, says Erik.

The recycled solvents maintain the same quality as traditional fossil-based  products, but with up to 81% lower climate impact depending on the solvent. The climate benefit has been confirmed by global climate organisation Exponential Roadmap Initiative (ERI). To encourage the development of low-emission alternatives to high- emission products, the ERI has launched the Climate Solutions Framework, which sets out criteria for climate solutions. In 2025, SRS became the third product to be  r ecognised as a climate solution under this framework.

– Having our climate benefits confirmed by such a reputable third party is hugely important, both to us and to our customers. Going forward, our focus will be on stabilising production with a view to expansion. With the technical solution, value chain, and demand already in place, nothing is stopping us from scaling up, says Lars.
