Bergen, Norway, July 14th, 2025 – M Vest Water (EURONEXT: MVW) today announces the successful completion of the qualification step of its NORWAFLOC® products at METHA, a facility operated by the Hamburg Port Authority.

The successful qualification has advanced MVW to the next step, a one-week verification run at the end of July. Upon repeated success, a long-term final qualification run in autumn 2025 will be the last step before final METHA approval, positioning MVW for further commercial negotiations with METHA.

Background:
With reference to the earlier announcement on October 22, 2023, MVW conducted a full-scale qualification test at one of the largest mechanical dredging sludge dewatering sites in Europe. During this test, dredging sludge was successfully treated for dewatering by replacing 25% of the synthetic polyacrylamide with the natural NORWAFLOC® product, achieving significantly improved dewatering results. Subsequently, the plant underwent major equipment upgrades.

In the meantime, MVW has announced a major breakthrough in product development, enabling NORWAFLOC® to replace 100% of synthetic chemicals These new environmentally friendly and innovative products have now been proven successful in a large-scale pilot at one of two large chamber filter presses at METHA.

About METHA:
METHA is a flagship in the dredging industry, due to both its size and role in sustainable dredging management. The dewatering plant dewaters all dredging sludge from the continuous operations required to keep the port open for the approximately 12,000 ships that arrive in Hamburg annually. On average, METHA dewaters 300,000 tonnes of sludge each year and has the capacity to treat 1,000,000 tonnes. As part of the Hamburg Port Authority, METHA is often referred to as “the washing machine of the port of Hamburg.”

“We highly appreciate the support and cooperation from METHA over the past two years. Their interest and support have been invaluable motivators and contributors to MVW reaching the milestone of replacing synthetic chemicals with nature-based NORWAFLOC® in dredging sludge dewatering applications. By introducing a competitive natural-based chemical for dredging, we support METHA and the Hamburg Port Authority's goal of reducing their carbon footprint and adopting an eco-friendlier approach across all their activities,” says Tor Olav Gabrielsen, Executive Chairman at MVW.
