Chemical-Free Soil Remediation
Our new, innovative, containerised steam-treatment system for contaminated soil, eradicates Japanese Knotweed, pathogens and weed infestations without the use of chemicals.
The equipment can treat 2-25 tonnes of soil per hour. Based at our Cwmgwili site or available to mobilise to larger sites, our new soil treatment eqipment is a game-changer in sustainable soil remediation.
Core Benefits
South Wales is a European hot spot for Japanese Knotweed. This invasive species can be problematic for landowners and developers alike. Our technology uses superheated steam to neutralise weeds, seeds and harmful pathogens in the soil, allowing soil to be safely reused. We can treat soil on our site in Cwmgwili or bring the unit directly to you.
Complete Eradication
We can completely eradicate pathogens in soil, giving peace of mind and avoiding delays to projects.
Safe Re-Use
Supporting the circular economy and sustainable land development, Treated soil can be safely reused and avoid ending up in landfill.
Chemical-Free
Using superheated steam and avoiding harmful pesticides that can negatively impact the environment.
Cost and Carbon Savings
By reducing the amount of soil going to landfill we are also reducing transportation costs and keeping your project on track.
Proven Soil Treatment Technology
We are the first business in the UK to invest in this technology, but the system has been used successfully throughout Europe.
In one recent project, the system enabled the reuse of 8,000 tonnes of previously contaminated soil, eliminating the need for approximately 400 truckloads of soil transport and generating savings of around £150,000. Its adoption aligns with emerging EU directives that prioritise soil reuse and the control of invasive species.
Europe faces the challenge of managing over 500 million tonnes of soil waste annually, This technology offers a sustainable, scalable solution that directly addresses both environmental and economic concerns.
How it works
-
Soil is fed into the heating chamber inside a converted shipping container
-
Super‑heated steam circulates to eliminate pathogens, weed roots and viable seeds
-
Clean soil is cooled, then safely reused on‑site or off‑site - no chemicals, no waste
The unit runs on diesel, biodiesel, electricity or gas for flexible deployment.
