Sandvik and Stamicarbon initiate a new buy-back project
03 March 2020
Sandvik and its strategic business partner Stamicarbon have initiated a new project to recycle high alloy steel by offering fertilizer customers a special buy-back solution when replacing equipment at their plants.
When customers in the urea fertilizer industry replace old equipment at their plants, Sandvik decommissions the old equipment and recycles materials from it. In this win-win model, equipment is replaced without intermediaries and Sandvik and Stamicarbon can buy back the special alloys.
The buy-back concept also aligns with the Sandvik ambition of reaching 90% in production system circularity. Knowing that the scrap consists entirely of Sandvik premium material will facilitate raw material handling in the steel mill. The partnership is also a perfect match as sustainability is as important for Stamicarbon as it is for Sandvik.
Apart from this program, the Sandvik fertilizer team is also proactively reaching out to old customers with an offer to buy back material from urea plants that have been shut down.
The project advanced late in 2019 when the first heat exchanger was bought back from a urea plant in the Netherlands. The outcome was very positive, and the buy-back solution will now be included on all new offerings to fertilizer customers when replacing equipment at their plants. Sandvik and Stamicarbon are also exploring standardization of the collection and recycling of high-quality metals for the future.
Coincidentally, the bought back heat exchanger was the very first test installation of Safurex tubes. Safurex is the name of the high-alloy duplex stainless steel made to withstand the corrosive environments present in the urea process.
