In case you missed our last installment of “Inside In Situ Thermal Remediation”, TerraTherm’s informational webinar series, you can find a recorded version here:
Life Cycle Assessment of In Situ Thermal Desorption and Improving the Sustainability of Source Removal
Presented by TerraTherm’s Co-Founder, Chairman and Chief Scientist, Ralph S. Baker, Ph.D., this webinar was recorded on December 4th, 2014.
Increasing attention is being given to making remedial activities more sustainable, i.e., by minimizing the environmental, economic and social impacts of remediation projects. TerraTherm has been actively involved in such efforts for over five years. This webinar will review our activities, which have included supporting Life Cycle Assessments (LCA) performed by a third party team of researchers based at the Technical University of Denmark.
The initial LCA was conducted at a Dense Non-Aqueous Phase Liquid (DNAPL) site in Reerslev, Denmark where Soil Vapor Extraction (SVE) and In Situ Thermal Desorption (ISTD) were compared with excavation/off-site treatment, and where several years of SVE operation were followed by rapid implementation of ISTD to protect one of the major municipal water supply wellfields serving the city of Copenhagen.
A subsequent LCA effort, published in Ground Water Monitoring and Remediation, examined materials of construction and operational parameters that offer the potential to further improve the sustainability of In Situ Thermal Remediation.
This webinar summarizes the LCA work as well as summarizes the results of this research and illustrate how they have begun to be implemented within recent TerraTherm projects.
