ECT Expands FJH Platform to Destroy PFAS Captured on Adsorbents
- Expanded licence agreement with Rice University to apply Flash Joule Heating (FJH) to PFAS-contaminated adsorbents
- FJH can achieve >99.9% PFAS removal from contaminated carbon media like GAC under controlled conditions
- On-site PFAS destruction platform targeting traditional water treatment media, reducing transport and incineration risks
Environmental Clean Technologies Limited (ECT) has expanded its licence agreement with William Marsh Rice University (Rice) to include the right to apply Flash Joule Heating (FJH) to PFAS-contaminated adsorbents such as granular activated carbon (GAC). GAC is widely used to remove PFAS from contaminated liquids and gases, particularly in water treatment systems. However, once saturated, the PFAS-laden GAC becomes a concentrated hazardous waste typically transported off-site for high-temperature incineration, which is energy-intensive and dependent on specialist destruction capacity. ECT's strategy seeks to address this limitation by enabling on-site destruction of PFAS captured on treatment media, minimizing cost and risk associated with incumbent destruction methods. FJH applies high-power electrical current through carbon-based materials to achieve rapid temperature increases within seconds, breaking the carbon-fluorine bonds characteristic of PFAS compounds and converting the GAC into high-value carbon products. Peer-reviewed research indicates FJH can achieve >99.9% PFAS removal under controlled conditions, convert 90-96% of fluorine to stable inorganic fluoride salts, and produce minimal volatile fluorinated by-products. This new technology is intended to position ECT to deliver further PFAS destruction capability across both soil and water treatment mediums, reducing reliance on transport and incineration pathways while minimizing secondary waste streams.
The Company will now progress development and validation of its on-site system for the mineralisation of PFAS from spent GAC using FJH, with the objective of advancing toward pilot-scale deployment, subject to technical and regulatory validation.
