Management commentary in interim results has noted efforts to maintain lean operations and to adjust overhead costs in response to these conditions.
Ballast Water Treatment Systems (BWTS)
A notable area of activity for Euro Tech is ballast water treatment systems (BWTS). The company describes BWTS as a response to requirements from the International Maritime Organization (IMO) and U.S. regulations aimed at preventing biological imbalance caused by ballast water discharged by ocean-going vessels.

The company also offers a ballast water port solution system, described as a system installed in port to provide ballast water treatment services for ships that do not have their own BWTS or have damaged systems. In some disclosures, this port solution is referred to as HarborBallast. PACT has been awarded contracts for ballast water treatment port reception systems in China, including projects for a Chinese state-owned petrochemical company in Guangdong province and a Chinese state-owned shipping and logistics company with a harbor port on Hainan Island.

Company communications mention activity and sales efforts in regions such as Turkey and other maritime markets.

To support international expansion, Euro Tech has stated that it incorporated a majority-owned Singapore entity, PACT Environmental Technology PTE Ltd., to better serve overseas clients and to increase participation in international tender processes. The company has also reported that PACT entered into an exclusive sales distribution and OEM partnership agreement with ERMA FIRST ESK Engineering Solutions S.A. of Greece, focusing on BWTS sales distribution in 20 European countries.
