Advanced PFAS Soil Remediation with KRYSALIS

Demonstration project in Korsør (Denmark) showcasing Haemers Technologies' Containerized Thermal Conductive Heating with integrated Re-Burn technology for the destruction of PFAS-contaminated soil. The project validated both effective PFAS removal from soil and on-site mineralization of extracted PFAS vapors while minimizing secondary waste and atmospheric emissions.

SITE DESCRIPTION

Treated Volume	60 tons of PFAS - contaminated soil
Thermal technology	CSTT
Main contaminant	PFAS
Site challenges	Persistent "Forever Chemicals" in low-permeability soil requiring complete destruction instead of contaminant transfer.
Project Timeline	Demonstration campaign – 2025

SOLUTION

Treatment Method	Containerized Thermal Conductive Heating (CSTT) with patented Re-Burn technology.
Treatment program	Two demonstration batches treating approximately 30 tonnes each to validate remediation efficiency and optimize energy consumption.
Contaminated Vapors Management	PFAS vapors extracted during heating and reinjected into the Re-Burn chamber operating above 1,400°C for on-site mineralization.
Process control	Continuous temperature monitoring, vapor extraction, combustion control and independent laboratory verification of soil, leachate and air emissions.
