Sif Holding NV and Dillinger Hüttenwerke have strengthened their partnership by signing an addendum to their long-term steel plate supply agreement. This addendum secures Sif's access to Dillinger's lower-emission heavy-plate steel for offshore wind foundations, aiming for full circularity of monopiles.

Additionally, Sif Decom, a Sif subsidiary, and Dillinger signed a memorandum of understanding to develop the decommissioning process for offshore wind foundations. This follows a joint research project with KCI and Dillinger on designing a monopile recycling factory. Sif Decom will now finalize the business case for this factory, and Dillinger will be invited to participate once the investment decision is made. The factory aims to close the circularity loop by recycling steel for Dillinger's low-emission production, advancing the supply of green steel plates for Sif's new XXXL monopile factory.
