NAICS 562211: Hazardous Waste Treatment and Disposal

NAICS 562211 – Hazardous Waste Treatment and Disposal encompasses the safe handling, treatment, stabilization, transportation, and final disposal of regulated hazardous wastes, including chemical, biological, and radioactive materials. This sector supports federal compliance with the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), providing critical services such as incineration, chemical neutralization, landfill engineering, and decontamination of contaminated sites. Government contractors in this space deliver specialized engineering solutions for remediation, waste characterization, and regulatory permitting, often working in high-risk environments requiring strict adherence to EPA and DOT protocols. This NAICS is integral to federal environmental stewardship, supporting cleanup missions across military installations, research facilities, and public health infrastructure. Top contractors in this sector include AAECON GENERAL CONTRACTING LLC, CONSULTECH ENVIRONMENTAL LLC, and RE-ENGINEERED BUSINESS SOLUTIONS, INC., representing a mix of small businesses and niche environmental engineering firms with deep expertise in hazardous materials management. These firms typically compete on technical capability, regulatory compliance experience, and rapid response capacity rather than scale, reflecting a market where specialized certifications and field operational proficiency are decisive advantages. The Department of the Interior, Department of Health and Human Services, Department of Defense, and Department of Justice are the primary federal buyers, driven by missions ranging from legacy site remediation at former defense facilities to the safe disposal of pharmaceutical and laboratory wastes from federal research labs and correctional medical programs. Demand is consistently tied to environmental enforcement actions, facility decommissioning cycles, and ongoing compliance obligations. The competitive landscape is characterized by high barriers to entry due to permitting, safety, and logistics requirements, creating concentrated opportunities for firms with proven track records in federal environmental remediation. Contracting trends favor integrated service providers capable of end-to-end waste management, from sampling and analysis to final disposal and documentation, with increasing emphasis on sustainable treatment technologies and real-time monitoring systems.
