Ex Situ Treatment of Contaminated Soils and Liquid Organic Wastes

Savron’s Ex Situ (STARx) treatment systems use the same patented process as the in situ STAR technology: smoldering combustion. The STARx process also uses a lot of the same “off-the-shelf” equipment as the STAR technology (compressors, blowers, vapor treatment), but is carried out in engineered soil piles placed on our HottpadTM systems. Hottpads are fully scalable and can be sized depending on treatment volume, available footprint, and treatment time requirements. These systems are ideal for stockpiles of contaminated soils, sites where surficial soils are contaminated, and for waste oils and sludges.
