Thermal Eradication of Japanese Knotweed

       Treated area

24 m²

          Thermal technology

In-Situ Thermal Treatment (ISTT)

       Main contaminant

Japanese Knotweed (Fallopia japonica)

        Site challenges

  Roadside infestation requiring complete destruction of underground rhizomes while avoiding excavation and herbicide application.

     Heating configuration​

16 heating tubes with secondary heating tubes to optimize heat distribution and reduce energy consumption, or 50°C for 3 days   

      Treatment Duration

May – July 2022

✅         Complete destruction of Japanese knotweed rhizomes.

✅         No regrowth observed during post-treatment site                              monitoring. 

 ✅          Laboratory regrowth testing confirmed the absence of                   viable rhizomes after thermal treatment.
