Purchase Order (Long-Term Trial) from METHA, a Flagship in the Dredging Industry

17 Oct 2025 09:46 CEST

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."
