Construction Steels with Niobium 

CBMM's Sintering II facility was built with high strength niobium microalloyed steel. Using high strength instead of regular carbon steel meant that 22% less steel was needed to complete the structure.  The entire supply chain benefits from decreased environmental impacts and increased cost savings resulting from the use of value added niobium products.

Water Conservation

One of CBMM's priorities is to excel in water management. Efforts by the technical staff of CBMM's Process Research Center to reduce the use of fresh water are paying off:  95% of the water currently used in the manufacturing process is recirculated and the goal is to reach 98% in the next two years.
