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[3] of pre-thickened dredging sludge per month. This

volume represents more than 1/3 of the 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."
