2025: The Year SoilSteam Took a Major Step onto the Global Stage
2025 – a breakthrough year for SoilSteam: from Norway to Sweden and the UK, and from demo to documented performance
2025 has been a year in which SoilSteam clearly moved from being a “promising technology” to a documented solution in real-world applications. We have experienced strong international interest, several important projects – and, not least, a clear direction: soil as a resource, not waste.
This was not just a demo – it marked that the market is now moving rapidly toward more circular solutions for soil management.
First major step in Sweden: EWGroup
In 2025, we took an important step into the Swedish market through our collaboration with EWGroup, which became the first operator in Sweden to implement the SoilSaver 20 at its facility in Flen. This marks the beginning of a broader commitment in the Swedish market, where the need for circular handling of soil masses and control of invasive species is growing rapidly.
Trafikverket and Svevia tested SoilSaver in a project in Umeå, Sweden
SoilSteam then entered into an agreement with Svevia and Trafikverket for the treatment and recovery of approximately 1,500 tonnes of soil masses infested with lupins in Umeå. The project was planned for completion during May–June 2025 and was described as SoilSteam’s first collaboration with Trafikverket in Sweden.
This sends a strong signal that our method addresses a growing need in European infrastructure projects: stopping the spread of invasive alien species while simultaneously reducing landfilling.
An international meeting place: SoilSteam Demo Day 2025
In the autumn of 2025, we gathered more than 200 participants from eight nations at Gjennestad in Vestfold for SoilSteam Demo Day. The event demonstrated how thermal treatment can transform contaminated or infested soil and peat into a valuable resource, both for construction projects and for greenhouse production.
Gavin Griffiths Group – Japanese knotweed and the first UK unit
In the UK, 2025 has been a breakthrough year. Together with the Gavin Griffiths Group, we have taken important steps to document effectiveness against Japanese knotweed. This work is linked to the launch of what has been described as the UK’s first steam treatment unit for soil at their facility in the summer of 2025.
This marks the beginning of a broader UK journey, where documentation and strong partnerships are central.
Our goal is to save as much soil as possible from being landfilled. During 2025, our fantastic customers used their SoilSaver machines to save more than 23,000 tonnes of soil from disposal. This took place in Norway, Sweden, and the UK. Without SoilSavers in the contracting industry, this would never have been possible. A huge thank you to everyone who made this happen 😊
Professional documentation and international relevance: Sardinia Symposium 2025
In September 2025, we also participated in the Sardinia Symposium, where we demonstrated how SoilSteam technology is already being used in practice across multiple segments – from road and construction projects to the reuse of growing media in greenhouse production.
For many, this comes down to a fundamental question: Is it possible to control pests and invasive species without destroying soil quality? Our experience and documentation clearly show that the answer is yes.
New applications: substrates and growing media
2025 has also been about growing media and circularity in greenhouse production. SoilSteam has published several articles on the reuse of substrates and how this can contribute to more sustainable production.
In the summer of 2025, we carried out our first research project documenting that peat and substrate products can be treated using our SoilSaver technology and reused instead of being replaced with new material. This represents a new way of thinking about circularity in international greenhouse production and will also lead to significant reductions in methane and CO₂ emissions.
New customers and new continents
The end of 2025 was intense. We held meetings with several stakeholders in greenhouse production, waste management, and the contracting industry across multiple countries. This resulted in several SoilSaver units being sold for delivery next year during the final months of 2025.
One of these units will be delivered to North America, becoming SoilSteam’s first machine operating outside Europe. This is a major milestone for SoilSteam.
What do we take with us into 2026?
2025 showed us three things very clearly:
- The need for circular soil management is growing rapidly – across multiple industries at the same time.
- SoilSteam is moving from “pilot” to “scalable practice.”
- We have documented that soil steaming works – and people understand it. During 2025, we were contacted by more than 200 companies from 24 countries interested in SoilSteaming. We believe this strong interest will grow even further in 2026.
Thank you to our customers, partners, and everyone who met us in 2025 – we look forward to building further in 2026.
Merry Christmas and Happy New Year!
