Dig & Dump for Japanese knotweed removal
Dig & Dump involves the physical excavation of all soils containing viable Japanese knotweed rhizome. These are then loaded into a lorry, typically an 8 wheeler 20 tonne payload, and transported to a licensed landfill site, for disposal.
There are significant adverse environmental impacts arising from haulage, the use of valuable landfill and the need to import clean fill. The Environment Agency Code of Practice clearly states that you should consider this as the method of last resort.
Supervision to reduce volume and cost
Dig & Dump is a very expensive method which attracts Landfill Tax. With expert supervision it is usually possible to substantially reduce the cost by minimizing the volume of soil being classified as knotweed infested.
With a trained eye, one can establish the depth and lateral spread of the rhizome system. The volume can sometimes be reduced by as much as 50%.
Compliance with environmental legislation
Particular care is required to ensure no viable rhizome is spread either on or off site during the operation. Procedures are put in place to ensure the Environmental Protection Act 1990 “Duty of Care” requirements are met. Environet is a registered waste carrier and ensures all waste is consigned to licensed sites authorised to accept Japanese knotweed.
