CAMP HILL, Pa., Feb. 16, 2021 (GLOBE NEWSWIRE) -- Harsco Corporation (NYSE: HSC), a global market leader providing environmental solutions for industrial and specialty waste streams, today announces that its Clean Earth Mobile Soil Services division has treated and beneficially reused nearly 450,000 tons of contaminated soil using mobile thermal remediation technology for a military contractor in Northwest Florida. Clean Earth’s mobile thermal treatment solution for contaminated soil exceeded the remediation goals for the project, attaining a 100% success rate for all soils treated and eliminating an estimated 22,500 truckloads of soil contaminated with chlorinated organic compounds from entering landfills.

Clean Earth, an industry leader in full-service, sustainable disposal and recycling solutions for hazardous and non-hazardous waste, offers mobile treatment solutions that are designed to meet each specific project’s desired remediation goals and site complexities.

Clean Earth’s Mobile Soil Services offers thermal desorption technology that effectively treats and processes hazardous, non-hazardous and high-moisture contaminated media, including pesticides, polychlorinated biphenyls (PCBs), hydrocarbons, chlorine compounds and more. Mobile capabilities enable thermal desorption treatment of contaminated soil to be performed at the project site, avoiding the high costs associated with traditional waste transportation and disposal methods.

Using the mobile thermal remediation equipment at the U.S. Department of Defense site in Northwest Florida, Clean Earth and the military contractor:

• Kept nearly 450,000 tons of soil from entering landfills.
• Eliminated the mining and import of 450,000 tons of backfill.
• Prevented the need for 22,500 truckloads of imported material to replace the contaminated soil and backfill the excavation.
• Exceeded the soil cleanup objectives set forth by the Florida Department of Environmental Protections (DEP), allowing for the soil reuse in residential areas.

“Clean Earth is leading the environmental industry by providing sustainable and cost-effective treatment of contaminated soil while preserving natural resources,” said David Stanton, President of Clean Earth. “Our versatile mobile remediation services enable customers to benefit from an on-site solution for contaminated soil, ultimately helping to minimize environmental impact and maximize value.
