Successful Full Scale Application of the STAR Technology to Clean Up a Former Coal Tar Facility in New Jersey
« All Projects

The first full-scale application of Savron’s STAR technology is underway. The 26-acre former coal tar site is located in Newark’s Ironbound district and is part of the port area re-vitalization which will generate new jobs and new opportunities locally and nationally. Geosyntec is the site consultant completing the remediation. Savron, a division of Geosyntec, is the exclusive provider of the patented STAR technology which is a self-sustaining process based on the principals of smoldering combustion to destroy heavy hydrocarbons.

DuPont was facing a vexing contamination problem, and transitional remediation would have been costly and pose significant safety concerns. DuPont contracted Geosyntec to assess alternative remedies and was introduced to the STAR technology managed by their Savron division. However, at that time, the STAR technology was in its infancy, and had only been demonstrated at the laboratory scale. Even a pilot test would require scaling up the STAR process by 100,000 times, and further, a completely untested engineering design would have to overcome many operational unknowns.

Through a series of pilot tests conducted to demonstrate “proof of concept” under field conditions, testing new specialized equipment, and to collect design information, Savron/Geosyntec gained DuPont’s and regulatory agency’s confidence that STAR was a viable technology and should be selected as the remedy for the site.

Savron/Geosyntec designed and/or procured the required equipment for the full-scale remedy as well as developed an innovative application strategy to minimize infrastructure costs associated with the 2,300 ignition events beneath the ground that are required to treat the targeted soil volume at the site. The project is well underway, and has conservatively destroyed over 20 metric tons of coal tar in the first 5,500 cubic yards of soil.
