Our ‘Zero to Landfill’ solution includes for the 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 encasement has on a number of high value contracts where space is a premium.
The advantages of this methodology are:
• Financial – an extremely competitive solution
• Instant solution – as quick as conventional excavation solutions
• No time restrictions – can be used at any time of the year
• No importing of expensive back fill
• ‘Zero to Landfill’ – environmentally friendly
• Legally compliant
