Wärtsilä has agreed to divest its Water & Waste business to the Swedish investment company Solix Group AB.

Water & Waste offers a wide portfolio of environmental solutions for the full spectrum of water and waste management at sea. From ballast water treatment to efficient wastewater systems, the technologies offered by Water & Waste contribute to operational efficiency, compliance and enhanced environmental performance across the vessel’s lifecycle.

As part of Wärtsilä Portfolio Business, Water & Waste has operated independently to accelerate performance improvements and unlock value to Wärtsilä through divestment. In 2025, the annual revenue of Water & Waste was EUR 54 million.

Bernd Bertram, Head of Portfolio Business, Wärtsilä says: “Wärtsilä Water & Waste has developed a broad range of specialised and proven environmental solutions for marine. Building on our earlier collaboration with Solix, Water & Waste will be well positioned to develop further and ensure continued value creation for its customers and highly skilled team.“

Subject to approvals, the transaction of Water & Waste is expected to be completed in the third quarter of 2026. Following this, Wärtsilä will have completed the divestment of all business units included in its Portfolio Business.
