The project integrates SSAB Zero™ steel, which is manufactured using fossil-free electricity, into railcars engineered for long-term durability. By utilizing high-strength materials, Greenbrier reduced the overall weight of the cars, which in turn increases payload capacity and lowers lifecycle emissions during operation. These units are now being deployed to Alter Trading Corporation, where they will begin hauling end-of-life steel for re-processing.
Greenbrier, SSAB and Alter Launch Closed-Loop Steel Recycling Railcars
Fifty new gondola railcars are entering service to bridge a critical gap in industrial sustainability. Built by The Greenbrier Companies, the fleet uses near-zero emission steel to transport recycled scrap directly back to SSAB’s Iowa facility, creating a continuous, self-sustaining loop that minimizes reliance on virgin raw materials.
Brian Comstock, Greenbrier’s Executive Vice President, described the venture as a practical application of circular economy principles. Rather than operating in silos, the three companies have aligned their supply chains to ensure that the steel used to build the transport equipment is the same material being recycled within that very system. This collaboration highlights a push toward industrial decarbonization that prioritizes performance and reliability alongside environmental impact.
