HONG KONG, June 9, 2026 /PRNewswire/ -- Euro Tech Holdings Company Limited (Nasdaq: CLWT) today announces the launch of its next-generation mobile hybrid facility designed specifically for the treatment of ballast water aboard maritime vessels. This cutting-edge product aims to facilitate compliance with the International Maritime Organization's D2 regulations and growing local environmental protection standards, particularly in Europe, where regulations are becoming increasingly stringent.

Our innovative mobile hybrid facility significantly enhances shipboard ballast water treatment ("BWT") capabilities by expanding both the efficiency and scope of treatment. The system not only addresses the critical issue of invasive species but also tackles a broader array of water contamination challenges, including residual chemicals, Total Residual Oxidants generated by electrolysis-type BWT systems onboard, and other pollutants that go beyond current regulatory requirements.

The versatile design allows for deployment from port terminals or barges using a containerized solution, and it is adaptable for trailer truck transit, providing maximum operational flexibility. The treated effluent can be discharged directly into nearshore waters, transferred to urban water treatment facilities for further processing or reuse, or reloaded onto vessels as clean ballast water.

As a pioneer in enhanced mobile ballast water treatment systems with hybrid functionalities, the Company is well-positioned to lead the charge toward greener shipping solutions. In alignment with this vision, the Company is actively seeking a potential partner within its existing distributor network in Europe to help launch local sales promotion, support and technical services in their respective countries. Upon identifying a suitable partner, the strategic partner and / or the Company will facilitate system showcases including sales and marketing as well as provide on-site operational service support for shipowners.

By introducing this advanced mobile BWT solution, the Company takes a significant step forward in minimizing the environmental impact of shipping and promoting a sustainable future for maritime transport.
