Stena Recycling Skarvik
At Stena Recycling's facility in Skarvik, Gothenburg, Helios Innovations implemented a unit to purify 8,000 m³ of heavily contaminated water where conventional treatment methods were insufficient, with a solution that reduces waste volume 20 times.
Gothenburg, Sweden
Tank wash water at the facility contained a mixture of oil residues, heavy metals, PFAS and other hazardous substances which made conventional treatment processes insufficient. An efficient and flexible solution was needed to ensure that emission levels were kept within permitted limits.
Advanced process control enables the facility to handle a wide spectrum of contaminants with maintained operational reliability through continuous monitoring.

What We Achieved
20x Less Waste
From 8,000 m³ of contaminated water down to just 400 m³ of concentrate sent for destruction — a 20-fold reduction in waste volume.
Consistent Compliance
Continuous sampling ensures that the treatment process consistently keeps discharge levels below regulatory limits.
Reliable Operation
Automated alarm systems and continuous monitoring ensure minimal maintenance and high operational reliability.
A Long-Term Partnership
The agreement between Stena Recycling and Helios Innovations spans five years, during which the plant will also be used to treat incoming water from Stena Recycling’s customers.
This makes it an important addition to the company’s treatment capacity and strengthens sustainability in the handling of hazardous liquid waste across the region.
