MVW today announces the successful completion of the third out of four qualification steps for its NORWAFLOC® products at METHA

Successful completion of the third step in the qualification process at METHA
has advanced MVW to the fourth and final step, as announced on July 14th,
2025. METHA is one of the leading facilities in the dredging industry,
recognized for both its size and role in sustainable dredging management.

The planned paid long-term trial (minimum one month duration) is scheduled to
start in Q4 2025. 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
identical chamber filter presses. Based on previous successful full-scale
trials, MVW estimates a consumption of around 15 tons of NORWAFLOC® per month
for the long-term trial at a single chamber filter press.

Upon successful completion of the final upcoming paid long-term qualification
run, and meeting both METHA's and Hamburg Port Authorities' expectations, MVW
will be technically qualified for further commercial negotiations with METHA
regarding long-term contracts.

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."

"MVW are very pleased that, through a small-scale verification and two
short-term full-scale verifications at METHA, MVW has demonstrated stable
performance and excellent technical results, enabling 100% substitution of
incumbent synthetic polymers with our innovative, natural-based NORWAFLOC® at
one of the largest dredging sludge dewatering plants in Europe. The good work
of our team in close cooperation with the client, has now qualified us for the
final stage," says Tor Olav Gabrielsen, Executive Chairman at MVW.
