Ebsford environmental was approached to remediate a site contaminated with historic landfill, asbestos, and Japanese knotweed. They designed a solution to process 6000 cubic meters of contaminated subsoil using Enviroscreen 2020, allowing 99% to be reused on site, saving £1 million in disposal costs. Key actions included separating waste streams, removing viability from knotweed rhizomes, and sending 151 tires, 100 tons of landfill waste, and 3700kg of asbestos to disposal while recycling scrap metal. The project also coordinated with ecological works and kept neighbors informed to successfully remediate the residential area site.

Complex remedial
scheme using
Enviroscreen 2020
Ebsford environmental were approached by the client with
a small suburban site hosting a former pond in one corner
of the site which had, over the years been subject to a
range of y tipping and inlling activities.
The contamination of these materials were highlighted at
an early stage in the development window, through initial
phase ground investigation works. Second and third
phase trial pitting was undertaken to more fully
understand the levels and types of materials present
leading to the production of a cost benet analysis
allowing the client to make an informed decision on the
type of remedial scheme to be employed.
The Ebsford team designed and implemented a solution to
undertake the management of 6,000 cube of subsoils
contaminated with historic landll, containing licensable
asbestos and Japanese Knotweed which would facilitate
the reuse of 99% of this material on site offering a cost
saving in the region of £1million against disposal to landll
due to volume and type of contamination.
This methodology kept vehicle movements to an absolute
minimum and prevented in the region of 600 haulage
vehicle movements within the residential area
surrounding site.
- Enviroscreen 2020 processing was used to separate waste
streams from the host material.
- Japanese Knotweed rhizome was separated to remove
viability and incinerated on site.
- 151 tyres, 100 ton of landll waste, 3700kg of bonded
asbestos sent to landll.
- Scrap metal passed for re use.
In the early stages of the scheme, close liaison with the site
ecologists was required to tie in with a badger relocation
scheme and reptile mitigation project.
The site, being in a high prole residential area, required
careful and courteous management of the
neighbourhood, with a notication undertaken in the early
project stage to keep residents with a direct line of sight
into the scheme appraised of the nature of the works given
the elevated precautions required for the asbestos works.
‘Ebsford Environmental - I would just like to express my
thanks to the Ebsford Team for providing a rst class
service when dealing with a series of environmental issues
on our behalf at Gibbet Hill, Coventry.
They have provided a superior service from project
inception to completion, have always acted in an
informative, open and client focussed manner, work on site
has been well presented and professionally managed and
just as importantly they have provided a transparent
commercial framework on a project where, due to the
complexity of mixed organic and inorganic contaminants,
a x price approach was not appropriate.
I would not hesitate to recommend Ebsford Environmental
for projects of a similar nature which involve Japanese
Knotweed and / or contaminated subsoils which require a
combination of in situ treatment and off-site disposal.’
