Profile

Perma-Fix Environmental Services, Inc.PESIIndustrials

Treats radioactive and mixed waste and delivers nationwide nuclear field services through Treatment and Services segments. Licensed treatment facilities support project and waste management, restoration, decontamination and decommissioning, construction, and radiological safety work for government, commercial-nuclear, hospital, and research customers.

Treats radioactive and mixed waste through four nuclear-waste treatment facilities. Treatment and Services are the reportable segments.

Its Services segment delivers project and waste management, environmental restoration, decontamination and decommissioning, construction, and radiological protection, safety and industrial-hygiene work. Customers include government, commercial-nuclear, hospital, and research organizations. These services are delivered nationwide at government and commercial sites.

The business shifted from industrial operations to nuclear waste services and added field-services capability through the Safety & Ecology acquisition. Treatment relies on licensed, permitted capacity; a renewed Richland permit governs mixed-waste processing and macroencapsulation there.
