Box Burner incinerating invasive species

Kingwell Holdings have a long history of incineration works with invasive species

Our S40 Box Burners  have a very low environmental impact. Volume reduction of material decreases the impact on landfill and local infrastructure by removing the need to transport material off-site. This process produces far less dust, noise, vibration and engine emissions than when other mechanical processing methods are used.  Our double burning process ensures no contaminated material remains, the perfect solution for dealing with invasive species

Kingwell have been involved in numerous invasive species projects since 2005, our experience and development in this field is ongoing.

Mobile burner on Knotweed disposal

No access for trucks to remove contaminated material. Working with Llynch Rail to safely incinerate contaminated vegetation and Knotweed material from stockpiled ballast.

After the surface vegetation has been incinerated, using a mobile Burnboss incinerator at over 1000 degrees Centigrade, a secondary operation to burn the screened arisings from the stockpiled material will then be carried out – all with no material movements on or off site.

The perfect solution for dealing with invasive species

Controlled high-temperature burning of invasive Gorse, for heathland restoration in Norfolk

Open public access on this common land meant that the Local Council decided that only a mobile airburner (high temperature incinerator) was suitable for the safe disposal of large volumes of invasive Gorse. This safe, controlled burning process enabled continuous burning, whilst giving safe public access to the common, during the works and with no nuisance caused by smoke or dust to nearby housing, the main road running alongside the site or the adjacent industrial estate.

Furthermore, the airburner reduced the material to less than 5% of it’s original volume, meaning that only a small amount of inert ash had to be removed at the end of the operation – eliminating damage to the sensitive site soils by trucks and other heavy equipment.

Rhododendron with Phytophthora eradication

Large-scale high-temperature incineration of material at Clyne Valley – a remote inaccessible site in South Wales. Difficult and steep site access meant that the only way to safely eliminate huge volumes of material, was by using two large mobile airburners, fed by a 20 ton sized excavator.
Despite soaking wet vegetation and bad weather conditions, imported wood waste was successfully used to burn the material – much of which was baled, using a forestry brash baler, mounted on a 8WD forwarder.

This project, managed to entirely eradicate thousands of tons of Phytophthora contaminated vegetation over several months, without a single HGV having to transport contaminated material off site.

Emergency Operation to Eliminate Asian Long Horned Beetle

Asian Long-horned Beetle (ALB), Paddock Wood

A large-scale emergency operation, to quickly eliminate one of the most serious pest outbreaks in UK history. ALB infestation in the UK would lead to devastating consequences for the UK tree population.

A rapid-response operation, that ran 24 hours a day, safely destroyed large volumes of ALB-infested trees and vegetation. Kingwell are the DEFRA Plant Health Framework for this type of work in England and Wales.

Asian Gall Wasp (AGW)

Kingwell were called in to process large volumes of infested material from an outbreak in Kent. Due to the adjacent M25 and nearby crops, it was decided to destroy the wasp galls in the vegetation, using one of  our RT400 forestry mulchers.

A quick test confirmed that this method completely destroyed the galls and eliminated the mass breeding and emergence of millions of new Gall Wasps into the surrounding countryside. AGW infestation is another Code Red species that must be prevented from entering and spreading across the UK, if irreparable damage to UK timber stocks is to be prevented.
