TWIRLS Project Workshop on Composting for
Contaminant Removal, Prague, March 2007
TWIRLS team members Susan Tandy and Julie
Williamson recently gave a workshop on composting for contaminant removal,
hosted by the Institute of Chemical Technology in Prague. Delegates included
students, academics and consultants to industry. During their visit, Susan
and Julie visited a number of contaminated sites including Spolana's chemical
plant contaminated with lindane and dioxins. A unique approach to remediating
the site has been adopted, involving indirect thermal desorption and basic
catalysed decomposition (BCD).

are completely enclosed and under negative pressure to avoid emissions
of dioxin-loaded dust during decontamination.
Susan and Julie also visited the Most open-cast
lignite mining area of N. Bohemia (Below). So vast, the mine extends into
Germany and Poland. Plans to restore the area as a lake for leisure activities
are complicated by shallow groundwater, heavilly contaminated with ammonia
from an adjacent petro-chemical plant.

TWIRLS Project Restoration Workshop and Field
Site Open Day, Greece, 13th December, 2006
The TWIRLS project team from Bangor University
and NAGREF / Soil Science Institute of Athens (SSIA), in partnership with
Titan Cement Co. S.A. hosted a successful restoration worksop and a visit
to TWIRLS field sites near Athens.

Project Launch, European Parliament, Brussels,
November 6-7th, 2006
TWIRLS research and demonstration work was
recently showcased in an exhibition at the European Parliament in Brussels.
All five TWIRLS staff travelled to Brussels armed with display materials
(boy did we get some strange looks passing through customs armed with
five, 1.5 m poster tubes!). On the evening of the 5th November, approximately
50 people attended presentations and a wine reception hosted by the TWIRLS
project. TWIRLS research and dissemination officer Dr Julie Williamson
introduced the project and was followed by Proffessor John Farrar (Pro
Vice Chancellor for Research at Bangor University) and Andrew Davies,
Welsh Assembly Minister for Enterprise, Innovation and Networks.
The TWIRLS team (Julie Williamson, Susan Tandy,
Mark Nason, Rhidian Jones and Jon Holmberg) hosted the TWIRLS project
launch at the European Parliament in Brussels. Attendees included Andrew
Davies, Welsh Assembly Minister for Enterprise, Innovation and Networks.

Blaenau Ffestiniog open day, October 12th
The TWIRLS project held a successful open
day at our in-vessel composting site and habitat creation experiments
at Blaenau Ffestiniog, Gwynedd. Approximately 25 people, including members
of the local community and respresentatives of the UK Environment Agency
and the Royal Society for the Protection of Birds joined us to discuss
our slate quarry restoration work on a landrover tour of our trial plots
and during poster presentations.

Welsh Soils Discussion Group visit to Blaenau
Ffestiniog, June 15th
The TWIRLS project hosted a
visit by 20 members of the Welsh
Soils Discussion Group (WSDG) on the 15th June. Drs Julie Williamson
and Susan Tandy led a tour of the natural ('target') vegetation and soils
adjacent to the TWIRLS project composting site before explaining the design
of our composting and vegetation establishment trials on slate waste.
The trip facilitated interesting discussion about methods of habitat restoration
and how best to use composted waste materials as soil forming media in
upland areas such as Blaenau Ffestiniog.

Site Open Day, Shotton, 18th May 2006
The TWIRLS project held a successful
open day at our in-vessel composting and meadow grassland establishment
trial site at Shotton, on Deeside. Approximately 30 visitors toured the
trials and witnessed a demonstration of our in-vessel composting techniques.
Many thanks to everybody who visited us, there are some photos of the
event below. We will be holding an open day at our rural slate quarry
trial site in September so check back here for details.
