Screening Process

Screening of soil containing Invasive Alien Plant Species (IAPS) material can be a very effective for many sites. Screening the soil involves removing viable rhizomes and other plant material by processing the soil through specially designed machinery and screen mesh, leaving the processed soil clean of vegetation. The processed soil can be re-used on site for landscaping etc.

​

Where ground permits, the screening of IAPS contaminated soil can reduce the volume of material for off-site disposal by up to 95%, resulting in substantial savings in transport and waste disposal costs. Similarly, in the case of on-site programmes, such as cell burial or bunds, the reduced volume of material requiring burial can lead to considerable cost benefits.

 

With difficult or restricted sites, the use of soil screening can mean the difference between being able to implement a complete on-site solution instead of using the higher cost of off-site disposal.

Japanese Knotweed Soil Screening Methodology: Spoil to Soil (S.T.S.) by Japanese Knotweed Control Ltd

 

Spoil to Soil (S.T.S.): Revolutionising Knotweed Remediation

Japanese Knotweed Control Ltd has pioneered an innovative and sustainable solution for managing Japanese knotweed (Fallopia japonica) infestations - the Spoil to Soil (S.T.S.) system. This cutting-edge soil screening methodology effectively separates knotweed rhizomes and plant material from soil, enabling clean soil to be reused on-site. S.T.S. significantly reduces the volume of soil requiring off-site disposal, offering both ecological and financial advantages.

 

Spoil to Soil (S.T.S.) Methodology

​

1. Comprehensive Site Assessment

• Survey and Mapping: Experts conduct thorough site inspections to map the extent of knotweed contamination. Depending on the terrain and size of site, ground assessments can include the use of drones, sniffer dogs and slit testing techniques. GPS mapping and soil sampling ensure precise data collection.
   

• Soil Analysis: Detailed analysis identifies knotweed rhizome depth, density, and distribution, aiding in the planning of the screening process.

​2. Controlled Excavation

• On-site reuse of soil eliminates the need for imported fill material, preserving natural resources and reducing quarrying activities.
   

3.  Minimised Carbon Footprint

• By treating soil locally, S.T.S. reduces transportation emissions associated with off-site disposal and backfill imports.
   

4.  Protection of Local Ecosystems

• Retaining soil on-site prevents habitat disruption and maintains soil structure, fostering healthier ecosystems.
   

5.  Enhanced Biosecurity

• Knotweed rhizomes are carefully isolated and disposed of, preventing contamination of new sites and aligning with biosecurity regulations.

Financial Benefits

1.  Cost Savings on Disposal

• Avoiding large-scale soil removal and landfill disposal dramatically lowers project costs.
   

2.  Reduced Backfill Costs

• Reusing existing soil eliminates the need to purchase and transport new fill material.
   

3.  Efficient Project Timelines

• The streamlined S.T.S. process reduces downtime associated with traditional knotweed excavation and disposal methods.
   

4.  Regulatory Compliance

• The S.T.S. method adheres to Irish environmental and biosecurity standards, reducing the risk of fines and delays.
