Thermal Eradication of Japanese Knotweed in a Port Environment

       Treated area

98 m²

          Thermal technology

In-Situ Thermal Treatment (ISTT)

       Main contaminant

Japanese Knotweed (Fallopia japonica)

        Site challenges

  Industrial port environment with numerous underground utility lines requiring a hybrid treatment approach and validation of thermal compatibility with electricity and telecommunication networks.

     Heating configuration​

Single treatment batch covering 98 m² using 66 Hot Screws™. Part of the infestation was treated in situ while another section was excavated and thermally treated under insulated wrapping due to underground utilities.

      Treatment Duration

 May–June 2025

✅         Treatment completed within 14 days, meeting the project              schedule before subsequent site activities.

✅         Long-term monitoring initiated by North Sea Port to                        confirm complete eradication over a two-year period.

 ✅         Chemical-free and sustainable solution for invasive plant               management in industrial environments.
