Industrial water treatment for harbours and ports.
See Solutions for Harbours & PortsOur cellulose-based packing material increases water surface area by 400x, enabling efficient evaporation at low temperatures without vacuum systems. The result: robust concentration of contaminated industrial liquids, reducing disposal volumes by 90% regardless of contamination type.
For decades, contaminated industrial wastewater has been hauled away and incinerated — expensive, carbon-heavy, and under growing regulatory pressure.
Weekly tanker pickups
Logistics costs compound regardless of treatment outcomes
High-temperature incineration
Burns fuel to destroy water — releases CO₂ and toxic byproducts
Costs scale with volume
No ceiling — the more waste produced, the higher the bill
Rising regulatory exposure
EU and Nordic emissions rules tightening every year
€1,500/t
Typical incineration cost per tonne of wastewater
On-site treatment
No tanker dependency — treat waste where it's generated
Evaporation, not incineration
Zero combustion — water returned cleanly to the atmosphere
90% volume reduction
Dramatically cuts the residue that still needs final disposal
Future-proof compliance
Aligned with EU industrial emissions directives today and tomorrow
16t
CO₂ avoided per year — proven at Stena Recycling
Helios eliminates the need to burn contaminated water.
Better economics. Lower emissions. Future-proof.
Waste Management
Challenge
Process water from various industries contains substances that are difficult to treat with conventional technology. Many flows carry high alternative costs and generate large waste volumes if left untreated.
Solution
A full-scale demonstration plant powered by residual heat — continuously treating mixed industrial water streams while serving as a testbed for next-generation purification materials.
Results
Backed by BackingMinds and growing 170% year-over-year, Helios is scaling proprietary atmospheric evaporation technology across European industrial markets. Our service model eliminates adoption barriers while building predictable recurring revenue — attracting both climate tech and industrial investors.
