Welding of geomembranes - CSWIP exam success for Greenstar in Ireland
Greenstar is Ireland's leading provider of environmental, waste management, skip
hire and recycling solutions. Greenstar's Ballynagran Residual Landfill opened in
October 2006, and is permitted to accept 150,000 tonnes of residual waste per annum
from Wicklow and adjoining counties.
Greenstar are committed to operating at the highest recognised standards, demonstrated
by having won several awards and achieved ISO 140001 and 18001 certification. They
approached TWI in early 2011 having identified a requirement to train a number of
operators in the welding of geomembranes. Having this expertise in house will allow
them to install new landfill cells and carry out capping works without the need
to employ external contractors. Greenstar also requested that their employees take
the CSWIP examination, so that the standard of welding achieved can be proven to
the relevant landfill operating authorities.
The tailored training course took place over 2 days at Greenstar's premises in Ballynagran.
Ten employees underwent the training and then took the CSWIP examination which was
carried out in accordance with the British and European Standard BS EN 13067:2003

John Jones, General Manager at Greenstar commented: 'All the guys at Greenstar were
delighted when they got an opportunity to learn a new skill. The first phase of
capping works at Ballynagran Landfill is now complete and it's been great to see
how people's welding skills and confidence have grown throughout this first project.
We are now set-up to be able to carry out landfill construction and capping projects
in-house which is going to cut out a lot of third party costs and save us money
for years to come.'
Ten welders took exams in heated wedge and extrusion welding, achieving an overall
pass rate of 85%. Where individuals failed they will undergo further training to
ensure they achieve the standard required.
