Salzgitter and Binding Solutions Partner to Develop Cold Agglomerated Granulate Technology
07/28/2025 - Binding Solutions Ltd (BSL) has partnered with the Salzgitter Group to conduct trials with its cold agglomerated pellets (CAPs) for blast furnace and direct reduction (DR) applications.
The aim of the trials is to show the value of BSL’s CAPs in blast furnaces and confirm its DR-GAP technology in a globally recognized test facility, the companies said.
“We believe our CAP technology has the potential to ensure a stable, long-term supply of high-quality, low-emission pellets to the European green steel industry,” said Jon Steward, chief executive officer of BSL.
The DR trials will be conducted at several of Salzgitter’s production facilities with various ore types while blast furnace trials will be conducted at other Salzgitter Group sites. Some of the DR test series will take place withing the 2,500 kg/d μDRAL innovation project: the world’s first flexibly hydrogen and natural gas–powered DR plant in an integrated steel works.
The CAPs are manufactured at BSL’s technology center in Teesside, U.K., before being shipped to Germany. The company’s patented CAPs can be used as a replacement for conventional curing and sintering materials in blast furnaces and DR plants. They estimate the CAPs reduce energy consumption and CO2 emissions by up to 80% and 70%, respectively.
“BSL’s innovative technology has the potential to ensure a secure and diverse supply of high-quality, low-carbon iron ore pellets for our steel production process and help us achieve our ambitious climate targets,” said Timo Naleschinski, head of raw materials purchasing at Salzgitter.
The companies said that if the test results are good, the process technology could be part of the SALCOS®-Salzgitter Low CO2 Program.
