CIRIA wants to raise profile of sustainable remediation techniques


CIRIA HAS launched a research project to raise the construction industry's awareness of sustainable remediation technology.

Titled 'Innovative non-biological treatment for contaminated land - case studies' the project aims to raise understanding and improve confidence in using 'innovative chemical, physical and thermal methods in the assessment and remediation of risk associated with land contaminated by non-radioactive and radioactive substances' The construction research organisation said rising landfill gate costs and the landfill tax meant there was an urgent need for construction professionals to look for more cost-effective and sustainable techniques for redeveloping brownfield.

While a wide variety of risk assessment and remediation techniques are now available, a recent survey showed that dig and dump is still used on 80% of brownfield redevelopment schemes in the UK.

CIRIA said UK construction professionals had little knowledge of techniques such as remote sensing, soil washing, active barriers and thermal desorption, particularly those which remove radioactive contaminants.
