AES Asset Acquisition Corporation

AES Asset Acquisition Corporation, doing business as Clean Earth, LLC, is a for-profit subsidiary of Harsco Corporation that operates exclusively as a single-customer prime contractor providing hazardous waste classification, removal, transportation, and disposal services to the Defense Logistics Agency Disposition Services on a full-and-open, non-set-aside basis. Headquartered in King of Prussia, Pennsylvania, and operating under NAICS 562211 (Hazardous Waste Treatment and Disposal) and PSC Housekeeping-Waste Treatment/Storage, Clean Earth holds a dominant position in DLA Disposition Services' hazardous waste management portfolio with no subcontract activity across its federal award footprint.

Clean Earth's service capability centers on RCRA and non-RCRA hazardous waste management across military installations domestically and in Puerto Rico. The vendor's concrete work portfolio includes removal, transportation, and disposal of RCRA hazardous wastes, non-RCRA wastes, universal wastes, compressed gases, polychlorinated biphenyls (PCBs), and per- and polyfluoroalkyl substances (PFAS) contamination; waste characterization and testing; hazardous waste container management; and asset disposition services across installations including Fort Riley, Kansas; Kings Bay, Georgia; McConnell Air Force Base; Mayport Naval Station, Florida; Ellsworth Air Force Base, South Dakota; and Offutt Air Force Base, Nebraska. Representative recent delivery orders include a $65,421.36 order (June 12, 2026) for hazardous waste disposal in Jacksonville, Florida; a $65,375.78 order (July 1, 2026) for PFAS liquids disposal in Adjuntas, Puerto Rico; a $41,338.16 order (May 12, 2026) for cyanide liquids and solids disposal; and a $32,295 order (June 12, 2026) for PFAS liquids exceeding 100 PPM at Fort Riley, Kansas.

Customer concentration is absolute: all 3,017 awards spanning 2014 through July 2026 have been issued by DLA Disposition Services, representing $105.8 million in combined potential value and $28.8 million in obligated dollars (27% of potential value). Clean Earth competes exclusively through DLA Disposition Services indefinite-delivery contracts. The vendor's primary parent vehicle—an IDC awarded July 22, 2025, with a $2.767 million ceiling running through July 21, 2031—has generated approximately 1,163 task orders valued at $8.7 million combined potential. Four additional active IDCs contribute $16.6 million in combined potential value across 1,548 task orders. Activity has remained stable at 290 to 343 awards annually over the past five years, with 343 awards issued in 2026 year-to-date. Within the next twenty-four months, 380 awards (combined potential value $3.6 million) reach completion and face recompete exposure.

Clean Earth operates with no socioeconomic set-aside designations and competes exclusively in full-and-open federal procurement with all work priced on a firm fixed-price basis. The vendor holds no positions on government-wide acquisition contracts, BPAs with other agencies, or multiple-award vehicles outside the DLA Disposition Services family. All awards are delivery orders against single-award or multiple-award indefinite-delivery contracts. The vendor's parent, Clean Earth LLC (a foreign-owned for-profit organization), anchors the corporate structure; AES Asset Acquisition Corporation operates as the contracting entity serving DLA Disposition Services across domestic military installations and Puerto Rico locations within designated service radii.
