Low Temperature Thermal Desorption World’s Choice in treating Organic Contaminated Soil

Entering United Europe requires candidate countries meet strict environmental standards. This truss combined with the cleanup standards set when privatizing the socialistic industries are making eastern Europe a deja vous of the United States in the late 70's. Fearing making the same mistakes as other countries the environmental ministries have been researching treatment technologies used in other countries. The Ministers are in the fortunate position to be able to review the treatment methods already in practice in Europe and the United States. Minsters and their representatives toured though out the US and Canada viewing various treatment technologies. One of the major stops in the US was at Phoenix Soil LLC in Waterbury CT which is a Green Globe company. During this review PSI’s Waterbury facility was host to over a dozen environmental dignitaries.

                                                                                     Representatives from the ministries of the Environment of
    Romania, Czech Republic, Hungary, as well as corporate
    executives in the oil and chemical producing companies 
    traveled to view this project first hand. Here they were
    studying the efficiency of Low Temperature Thermal
    Desorption in the treatment of organic contaminated soil.
    They were comparing LTTD with the many other techniques
    that either have been or currently are being utilized to
    treat organic contaminated soil over the past years. The
    conclusion of the Environmental Ministers’ commentary on
    this review overwhelmingly reports that Low Temperature
    Thermal Desorption (LTTD) is the primary treatment choice
    for organic contaminated soil. LTTD effectively treats a wide
    range of contaminants including gasoline, diesel, jet fuel,
    fuel oils, motor oils, coal tars, Bunker-C, and other heavier
    hydrocarbons. One important factor for this decision is that
    LTTD treatment is immediate and complete. Highly
    contaminated soil enters the LTTD unit and approximately
    twelve minutes exits without detectable levels of organics.
    The other techniques including bioremediation and soil
    venting were found to require many months to completely
    treat the soil and still have the potential to release most of
    the contamination into the air or groundwater.

With the encouragement of the Hungarian Environmental Agency, Green Globe LLC competed with four other US companies to do a remediation of oil contaminated sludge and soil in the city of Budapest. The Connecticut regulations were adopted as a temporary air standard setup up by the Ministry of the Environment. the standard to meet. Green Globe LLC owned by David Green also the owner and operator of Phoenix Soil LLC was awarded this project. This was eastern European’s first soil remediation project utilizing LTTD and therefore generated much

interest. Dignitary training included on site tours as well as classroom. This first project consisted of 24,000 metric tons of Bunker-C petroleum contaminated soil and sludge from nine unlined oil storage lagoons. The soil averaged 120,000 ppm total petroleum hydrocarbons. The plant averaged 50 metric tons/hr and completed the project two months ahead of schedule. Stack testing was conducted unannounced on actual operations as is the requirement of the Hungarian Environmental Ministry. The stack test results showed that the facility was in full compliance of the permit. Green Globe LLC is currently awaiting for Government appropriations to finish the 160,000 metric tons second part of the cleanup.

The results from this demonstration has validated the opinions of Green Globe and the Environmental Ministries of Eastern Europe among others, that LTTD is the best available technology for soils contaminated with organics.
