Pollution-reducing geosynthetics and their development were discussed at an in-person talk hosted by IGS UK.
Christopher Quirk, managing director of Naue Geosynthetics, spoke on ‘Biodegradable nonwovens for geotechnical applications: the first in a new generation of geosynthetics’.
The face-to-face event in Warrington, UK, co-hosted by ICE North West (ICE NW) Geotechnical Group, explored the principles of a biodegradable geotextile and where it fitted in with standard products used in the industry.
Mr Quirk shared the application example of use at the common land at Northam Burrows in North Devon, UK, a seaside dune system designated as a Site of Special Scientific Interest and Area of Outstanding Natural Beauty.
Natural England, a public body that advises the UK Government on the natural environment, said any geotextiles used in construction on the site – which included the Visitor Centre and vehicular access road – should be plastic-free. The geotextile used was manufactured exclusively from organic, natural, renewable raw materials, and certified as 100% biodegradable by TÜV Austria. It delivered similar properties of separation, filtration and protection to a traditional plastic non woven geotextile.
Twenty-one people attended the talk last month, with several expressing an interest in the technology and progress being made for certain applications and environmentally-sensitive regions.
