Recycling Firm Launches Groundbreaking Technology to Tackle Japanese Knotweed
Waste management and recycling company Gavin Griffiths Group has launched a new piece of technology that kills pathogens in soil using steam treatment.
The firm has invested in a new unit, which is the first of its kind in the UK. The technology is capable of eradicating Japanese Knotweed and restoring soil health without the use of chemicals. The firm described it as 'a major step forward for sustainable land management' and said it will benefit a wide range of landowners, industries and private homeowners.
The technology was launched at Gavin Griffiths Group's Cwmgwili site and was attended by industry stakeholders, academics and government representatives.
Invasive plant species such as Japanese Knotweed are one of the leading threats to biodiversity and infrastructure in Europe. Over 500 million tonnes of soil are dumped in landfills annually across the EU because of harmful pathogens. According to the United Nations, up to 90% of the world's topsoil could be at risk by 2050 unless new remediation practices are adopted. The traditional removal methods of spraying, weeding or burial are costly, time-consuming and largely ineffective.
This new technique of soil treatment uses superheated steam to neutralise weeds, seeds and harmful pathogens in the soil, allowing soil to be safely reused. Other territories in Europe, such as Scandinavia have already widely adopted this new system where it's been shown to reduce soil disposal by thousands of tonnes and cut project costs dramatically.
Gavin Griffiths, Managing Director of Gavin Griffiths Group, said:
'We are proud to be the first in the UK to bring this game-changing technology to market. Our Innovation & Remediation Division has been searching for a solution like this for some time as it's one of the biggest issues to face our clients. This technology not only helps us to protect native ecosystems, but it also supports our circular economy goals by allowing treated soil to be reused safely and sustainably. We believe that this is a crucial step towards greener land management.
'This new addition to our portfolio of sustainable land remediation solutions complements our wash plant facility in Cwmgwili which already processes hundreds of thousands of tonnes of construction and demolition waste, recycling it into washed, recovered aggregates that can be re-used on other projects. Our commitment to innovation and bringing forward technology that enhances the environment is at the forefront of our operations and we are excited to see the impact that this can have for clients in South Wales and throughout the UK.'
Its impact on a range of different sectors including farming and property development will be hugely positive, according to Aled Owen, partner at HCR Law which specialises in agriculture, environment and estates.
He said:
'Japanese knotweed according to government reports can cause damage of up to 10% on property and production values, if left untreated. The damage and nuisance claims resulting from such a failure to address these issues are significant and costly.
'The legal duty to manage and control this invasive species is fiercely enforced with the complete range of civil and criminal penalties involved. Action to take practical, immediate and diligent action is determinative to show that the landowner has acted correctly so there would be for the landowner a defence or limitation of liability. The introduction of this system bringing the best of industry standards would be a significant tool in addressing an important environmental issue and addressing a landowners duty of care or a robust defence. The use of such new innovative processes must be considered a positive change in the farming and other property sectors. '
The unit is based at Cwmgwili but can be transported to larger remediation project sites throughout the UK as required.

JR East is raising its prices starting in March 2026
As we all know, Tokyo has one of the best public transport systems in the world. Unfortunately, maintaining that standard requires serious moolah, and passengers will soon feel the effects. According to Japan Today, JR East announced on August 1 it will be increasing its fares starting March 2026, a move that somewhat incredibly marks the company's first price increase since its founding in 1987 (consumption tax increases notwithstanding). The railway operator had applied for government approval to raise fees as early as last December, when Executive Vice President Chiharu Wataru announced his company must 'spend effort and money on safe railway operations'. The increases are estimated to bring in ¥88.1 billion in revenue annually – money that JR means to invest in equipment and repairs, as well as use to raise wages for staff and offset rising operational costs. On average, fares will rise by 7.1%, with the base fare for central Tokyo's Yamanote Line increasing ¥10, from ¥150 to ¥160. As always, IC card users will have slightly lower rates compared to paper ticket holders (between ¥8 and ¥9 increase), so we recommend getting yourself one of those to save a yen or two. If you're a bit of a stickler for paperwork, you can find the full Japanese report on the increase here.

West Wales firm steams ahead with new Japanese knotweed treatment
Their new systems is the UK's first mobile soil treatment technology designed to combat invasive species that threaten biodiversity and native ecosystems. The new system, launched at the company's Cwmgwili site in South Wales, uses superheated steam to eliminate harmful pathogens, invasive root systems, and seed banks from contaminated soil. The chemical-free process enables the recovery and reuse of treated soil, supporting habitat restoration, climate action goals, and circular economy principles. South Wales is a European hotspot for Japanese Knotweed, a fast-spreading invasive plant that damages ecosystems and infrastructure alike. Invasive non-native species (INNS) cost the UK economy over £1.8 billion annually and are identified by the UN as one of the top five drivers of global biodiversity loss. Gavin Griffiths, Managing Director of Gavin Griffiths Group, explains: 'We see the restoration of healthy soils as critical to fighting climate change and reversing biodiversity decline. "This technology allows us to treat soil in a chemical-free system that both remediates the land and retains its ecological value. It's a real game-changer for conservation and regeneration projects.' The soil treatment unit has already gained the support of environmental consultants, ecological surveyors, and regulators. The technology enables previously contaminated land to be brought back into beneficial use without contributing to landfill, making it highly suitable for use on protected sites, former brownfields, nature recovery zones, and community green spaces. The unit is fully mobile, allowing deployment on-site for ecological restoration projects across the UK. Its introduction complements the company's broader environmental portfolio, which includes the recovery of aggregates from construction waste through its established wash plant. Gavin Griffiths Group's Innovation and Remediation Division has been instrumental in driving forward the investment in the unit. Its impact on a range of different sectors including farming and property development will be hugely positive, according to Aled Owen, partner at HCR Law which specialises in agriculture, environment and estates. He comments: 'Japanese knotweed according to government reports can cause damage of up to 10% on property and production values, if left untreated.

'The legal duty to manage and control this invasive species is fiercely enforced with the complete range of civil and criminal penalties involved. "The introduction of this system bringing the best of industry standards would be a significant tool in addressing an important environmental issue and addressing a landowners duty of care or a robust defence. "The use of such new innovative processes must be considered a positive change in the farming and other property sectors. ' The traditional options of excavation, herbicide treatment, or burial are often ecologically damaging, legally complex, and carbon-intensive. In contrast, this new steam-based solution provides an evidence-based method to restore degraded land while improving outcomes for wildlife, soil quality, and water safety.
