PURCHASE ORDER (LONG-TERM TRIAL) FROM METHA, A FLAGSHIP IN THE DREDGING INDUSTRY

M Vest Water (MVW) today announces to have received a purchase order on commercial terms from METHA for a long-term trial at the dredging plant in Hamburg.

The long-term trial is scheduled to start in November and will run for minimum one month. Upon successful completion, and meeting both METHA's and Hamburg port Authorities' expectations, MVW will be technically qualified for commercial negotiations with METHA regarding long-term contracts.

MVW will supply its natural NORWAFLOC® products for the dewatering of approximately 10,000 m of dredging sludge per month. This volume represents more than 1/3 of the 3 pre-thickened current average volumes treated at METHA. The trial will be conducted using one of the plant's two chamber filter presses.

Background:

With reference to the earlier announcement on August 13, 2025, MVW successfully completed the third out of four qualification steps for its NORWAFLOC® products at METHA in August.

METHA is a flagship in the dredging industry, recognized for both its size and its leading 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 each year. On average, METHA dewaters 300,000 tons of sludge annually, with the capacity to treat 1,000,000 tons. As part of Hamburg Port Authority, METHA is often referred to as "The washing machine of the Port of Hamburg."
