Miljöfabriken, an environment‑focused recycling facility, has a strong environmental profile. The facility receives soil masses primarily from construction and infrastructure projects and is entirely free from construction materials such as gypsum, glass, and insulation. The materials offered for sale range from crushed rock products like macadam and stone dust to locally produced soil products, as well as recycled materials such as asphalt and concrete aggregate and compactable fill material for roadwork and similar applications. The facility achieves a recycling rate of 95% for all incoming material.

Challenges

Swedish Hydro Solutions has analysed water from the site and its collection pond, which currently forms part of a fully closed system. The samples show elevated levels of TOC (Total Organic Carbon) and several heavy metals—cadmium, copper, lead, chromium, mercury, nickel, and zinc—contaminants commonly found at landfill and recycling facilities.

The project’s main focus contaminants are lead, zinc, and TOC. The Swedish Hydro Solutions system manages both the heavy metals and the TOC load.

– The nearly 10‑year‑old treatment system simply could not meet the requirements of a Class B permit. We are now scaling up and switching to a future‑proof solution tailored to our needs, says Peter Östlund, CEO of Miljöfabriken.

How water is managed on site

The 1.4‑hectare operational area consists of a hardened surface sloping toward a ditch filled with macadam and lined with geomembrane. Several drains across the site collect stormwater and convey it onward. The hardened surface is sealed but not fully asphalted, which means water runs off the surface while a small portion infiltrates naturally into the ground.

The stormwater then flows or is pumped into a sealed collection pond, and these volumes are treated in the new system. The treated water is subsequently discharged into a 1.3‑hectare constructed wetland—a habitat designed to maintain open water for frogs and salamanders—before it finally flows into the Sege River.

Installation at the edn of March

Miljöfabriken’s existing water treatment system is currently at Swedish Hydro Solutions’ head office in Alingsås, Sweden, where it is being rebuilt and fitted with new storage tanks and a monitoring system. At the same time, an additional container is being prepared to meet both current and future requirements. Swedish Hydro Solutions is also supplying a FluorofIX® container equipped with 12 filters in a lead/lag configuration, including both activated carbon and glass media, along with other equipment required for the project.

Through a smart configuration where the filter container includes at least three stages with different filter media, the system can be adapted as the contaminant profile changes—ensuring compliance with all requirements over time.

The goal is clear: a permanent treatment system that meets the new, stricter performance standards while also being prepared to handle future PFAS requirements.

Installation in Oxie is scheduled for the final week of March.
