Dutch offshore foundations maker Sif Holding NV and German platemaker Dillinger have entered into a new partnership to achieve full circularity of the monopiles they produce together. The two companies have an existing long-term steel plate supply framework agreement, with Sif sourcing Dillinger's lower-emission heavy-plate steel for its offshore wind foundations.
The new agreement between Sif subsidiary Sif Decom and Dillinger stipulates the partners will work together on the decommissioning and recycling of monopiles at the end of their operational life. Sif Decom will handle the dismantling and recycling of the monopiles, while Dillinger will reuse the steel in its production process, closing the loop on the circular economy of monopiles.
This partnership builds on the companies' existing collaboration and demonstrates their commitment to sustainability and reducing the environmental impact of offshore wind projects. By ensuring the steel used in monopiles is recycled and reused, Sif and Dillinger are making significant strides towards a fully circular value chain for offshore wind foundations.
