We were contacted by our client – A Property Developer in the Warwickshire area, to carry out a survey as Japanese Knotweed was found on one of their sites in the Nottingham area.
Following the site survey, we quoted the client our ‘Zero to Landfill’ solution, including excavation, screening, separation and relocation of the Japanese Knotweed on site using our Environment Agency (EA) approved methodology.
The screening process removes the Japanese knotweed material from the soil and separates the subsequent arisings into two piles; one contaminated Japanese knotweed for incineration and one low-risk soil.
This approach removes the need to send controlled waste to licensed landfill and keeps costs to a minimum.
The time needed to process the stockpile depends on the composition and consistency of the material. Once screening has finished we will transport the knotweed rhizomes and vegetation to a waste transfer centre for onward incineration.
The screened soils can then be used as backfill for the void created by the JKW excavations.
We have successfully employed this method of screening on a number of high value contracts.
The advantages of this treatment are:
- · Cost effective for the client
- · No time constraints
- · ‘Zero to Landfill’ – environmentally friendly
- · Meets legal compliances
