Supporting Technologies

Perma-Sort®

Perma-Fix's Perma-Sort® is an automated, conveyor-based system for radiological characterization and segregation of bulk materials. Developed by nuclear engineers and Certified Health Physicists with 20+ years of experience, it delivers 100% material assay with high measurement quality. The system reduces end-point uncertainty for both disposal-restricted and unrestricted-release materials.


PFF Office

Key Features

  • Rapid mobilization and setup
  • Versatile discharge options
  • Low emissions and noise
  • Handles diverse material profiles
  • Comprehensive waste management (sorting, transport, profiling, inventory, manifesting)
  • Exceeds regulatory health and safety standards

Bulk Processing Units

Perma-Fix's Bulk Process Units (BPUs) use advanced thermal processing (combustion) to treat both liquid and solid LLW, achieving significant volume reduction–up to 100:1. Operating at 1800°F, the BPU breaks down all organic materials, leaving behind a stable residue suitable for disposal. This innovative technology meets the strictest U.S. and international standards.


PFF Office

Perma-Fix operates two BPUs:

  • A batch process for solid LLW, using stainless steel burn boxes to ensure complete separability of waste streams and prevent cross-contamination
  • A continuously fed system primarily used for liquid LLW

The BPU handles a wide variety of radioactive and contaminated materials without requiring segregation of combustible and non-combustible items. It is also equipped with pollution control measures designed to meet the most stringent emission standards.


Perma-FAS

Water Treatment

Perma-Fix has patented and commercialized a hydrolytic chemical destruction treatment for per- and polyfluoroalkyl substances (PFAS) that achieves greater than 99.9999% destruction of both short- and long-chain PFAS. The commercial-scale liquid waste batch reactor, Perma-FAS, operates at lower temperatures and pressures compared to alternative destruction technologies.


This technology has been proven effective for a variety of PFAS-contaminated waste streams—from low-concentration liquids to concentrated products such as AFFF, with concentrations up to 15,000 to 30,000 parts per million (ppm), pre-treatment.







Project Highlights

Perma-Fix UK has delivered a wide range of specialized projects supporting international and government clients in radioactive waste management, contaminated land remediation, and radiological protection. A small snapshot of some of our most notable work:


Mercury Leach Test Trials — United Kingdom

In collaboration with Wood (formerly Amec Foster Wheeler), we supported the production of the AMLGM process to conduct leach test trials simulating mercury leaching behavior from waste packages at the Low-Level Waste Repository (LLWR).


Environmental Remediation — Kiritimati (Christmas Island), Pacific Ocean

On behalf of the UK's Defense Estate Services Infrastructure (DESI), we conducted extensive land surveying, waste removal, and site cleanup. The project also included the installation of clean water systems for the local population to support environmental recovery and community health.


Radiation Protection Advisory Services — SEPA

We provided Chemical, Biological, Radiological, and Nuclear (CBRN) preparedness services, including:

  • Expert RPA consultation
  • Simulated emergency response scenarios
  • Participation in UK government workshops and planning meetings

Former Eveready® Battery Landfill Site — United Kingdom

Services at this legacy landfill include:

  • Monitoring and maintenance of passive reedbed treatment systems
  • Landfill gas monitoring
  • Sampling and analysis of contaminants
  • Environmental data interpretation and predictive modeling

FOOT-AND-MOUTH DISEASE Burial Site — County Durham, United Kingdom

We designed, installed, and operated a custom leachate treatment system for this sensitive site. Post-operational monitoring continues, with ongoing assessment of treatment performance and evaluation of long-term remediation options.
