When herbicide treatment isn’t enough to remove Japanese Knotweed, then excavation and disposal may be your only alternative. When thinking about knotweed disposal, it’s essential to adhere to certain rules. Failure to do so may result in a fine or prosecution. There are several legal provisions in The Environmental Protection Act 1990 that designate Japanese Knotweed contaminated stems and soil as “Controlled Waste”. That means that only licensed companies may eradicate such waste from a property and should take it to a properly licensed waste facility. Japanese Knotweed Uk┬ádisposal requires trained personnel, and it’s not something untrained people should do. That is primarily because:
1. Japanese Knotweed should be prevented from spreading into the wild.
2. The Knotweed should be prevented from spreading to your neighbour’s property.

The Japanese knotweed has two parts; the part you can see above the ground and the roots and rhizome which are hidden below the ground. The rhizome can be up to 4 meters beneath the ground and tend to spread up to seven meters. Therefore, excavation will involve the removal of both parts. The next step is disposing of the plant. The excavated soil, as earlier mentioned is regarded to as controlled waste and should be carefully handled. All regulated waste should be disposed of properly to a licensed landfill. Keep in mind that is you use a licensed landfill location to dispose of the waste, you are entitled to landfill tax.

There are various methods of eradicating Japanese Knotweed UK:

Dig and Cap
This is quite an effective remediation method where the amount of excavated Japanese knotweed is minimised. After the digging, there may still be contaminated soil left, and it has to be capped using something known as a root barrier. This helps prevent the regeneration of the plant. This process minimises soil wastes by just excavating to a particular depth, identifying the contaminated soil and just removing that waste.

Dig and Dump
As the name implies, this process involves digging up the contaminated soil and dumping it in a landfill. Only the contaminated soil is dug and removed, and the rest is left intact.

Dig and Sift
This method is best for Japanese knotweed infestations over vast areas. The contaminated soil is dug and passed through a screener. It is then sifted, crushing the Japanese knotweed and therefore reducing its regenerative power.

Cell Burial
In this method, the knotweed is excavated and then buried on site in a chosen location. The soil that has been contaminated is often buried below soft landscape areas because of the possibility of settlement.

Relocation
This method involves removing the knotweed contaminated soil and taking it to a nearby location. Unlike dig and dump, the waste is not taken to a licensed landfill, but to a nearby location instead. This can be quite cost-effective if you are planning to use the land for development.

Keep in mind that Japanese knotweed excavation and disposal is a major procedure and requires a special set of skills and knowledge to pull of. As such, ensure you choose a reputable Japanese Knotweed UK removal company for the job.
