PFAS purification at Stena Recycling

At Stena Recycling in Halmstad, Helios Innovations operates Europe's only dedicated facility for treating heavily contaminated PFAS water, an innovation platform that transforms discarded fire extinguishing foam and extinguishing water into clean water.

Halmstad, Sweden

Stena Recycling
Challenge

Discarded fire-extinguishing foam consists of over 97% water but contains extremely persistent PFAS chemicals that require special handling. Previously, entire water volumes were sent to high-temperature incineration at significant cost with no local treatment alternative.

Solution

A dedicated PFAS purification facility powered by residual heat that concentrates the contaminants so that only the concentrate needs to be destroyed while also serving as an innovation center to optimize PFAS purification technology.

Our results

Reduced costs

Only the concentrate is sent to high-temperature incineration, which reduces treatment costs by approximately 30% compared to incinerating the entire water volume.

Reduced waste volumes

Up to 90% of the heavily contaminated PFAS water becomes clean water, which drastically reduces the volume that needs to be destroyed.

Central PFAS hub

Through the partnership with Stena Recycling, the facility functions as a hub where industrially heavily contaminated PFAS water from multiple actors in Sweden and the Nordic region can be collected and treated safely.

Looking Ahead

Scaling PFAS Treatment Across Europe

The partnership with Stena Recycling enables secure, local, and energy-efficient PFAS treatment while Helios continues to develop the technology in practical operation.

The facility demonstrates how PFAS-contaminated water can be handled safely, locally, and energy-efficiently — a model that can be replicated at industrial sites across Europe as PFAS regulations tighten.
