HONG KONG, Oct. 12, 2026 /PRNewswire/ -- Euro Tech Holdings Company Limited (Nasdaq: CLWT) today announces its entry into Norway through a 50/50 joint venture ("JV") agreement signed between Sea Clean AS ("Sea Clean") and its wholly owned subsidiary, Euro Tech Global Pte Ltd. CleanPACT Environmental and Marine Engineering AS ("CleanPACT") is the name of the JV company.

CleanPACT will serve as a Customer Experience Center for port ballast water treatment, offering customers hands-on demonstrations, expert servicing, realistic simulations, and tailored training with the Company's next-generation mobile hybrid system (PortoBallast is the trade mark of the system) designed to treat ballast water from UV and electrolysis type ballast water treatment systems that do not meet discharge compliance requirements aboard vessels. The JV combines the Company's technology, expertise, and capabilities with Sea Clean's local knowledge, port experience, and market reach to clients.

Sea Clean is now setting up and commissioning the PortoBallast which has recently arrived at Sea Clean's port site in Torvastad, Norway.

In addition, the new JV will promote the PortoBallast across Scandinavia as a stepping stone to entering the European market. The Company believes this positioning will give it a new sales platform for global promotion.
