Burning and Onsite Burial of Japanese Knotweed for Developers
| Spray | Injection | Dig & Dump | Cell Burial | Root Barriers | Stockpile | Grazing | Insects | Sifting | Burning | Combined Methods |
Controlled burning of stem and crown material may be used as part of the control programme. Excavated roots can also be burnt. This reduces the viability of material and the volume for burial or off site disposal. Such burning must take into account any local by- laws and take account of the potential for nuisance or pollution that may occur as a result of the activity..

Burning in the open may be undertaken in accordance with a registered exemption as described in Paragraph 30 of Schedule 3 of the Waste Management Regulations 1994. The exemption also covers associated storage, which will allow for the drying of the material that is likely to be required before burning can take place.
Japanese Knotweed stems can be left on site after cutting in preparation for burning if
- The stem is of sufficient size to prevent dispersal by wind or traffic movement.
- There is no risk of dispersal into a watercourse
- The stem has been neatly cut near its base using a cutter, hook or scythe
Where the activity is taking place on a site other than that specified in para.30 of the 1994
Regulations, then provided all the other criteria are met (including the Relevant Objectives in schedule 4 of the 1994 Regulations) the Environment Agency would not normally consider pursuing enforcement action. Soil containing knotweed material and burnt remains of knotweed may be buried on the site of production.
Ideally, at least one application of non-persistent herbicide will have been performed to reduce the vigour of infective material. Soil to a depth of at least 3m and within a perimeter of 7m of the plant growth area should be excavated for burial. Site managers should check the periphery of the excavation for rhizome, to ensure that an adequate volume of material has been removed to account for all of the infective material. On site burial must be performed to a depth of at least 5m The potentially viable knotweed material should then be covered with a geotextile layer (e.g. Lowtrak) or a heavy gauge polythene sheet prior to infilling
