US: Heidelberg Materials North America have supplied slag and Portland cement for the construction of TSX Broadway in New York City. The construction involved advanced demolition and building techniques, utilising concrete's properties for strength and stiffness.

Stan Trella, Sales Manager Metro New York/Long Island at Heidelberg Materials North America, said "The use of slag cement was beneficial in multiple ways. Not only does slag cement optimise concrete’s strength, but it reduced the environmental impact of this high-profile venue by lowering the percentage of ordinary Portland cement in the mix."

India: The Indian Green Building Council (IGBC) has certified the sustainability claims of Dalmia Cement’s portfolio of blended cements. The portfolio consists of composite cement, Portland pozzolan cement and Portland slag cement. The council employed a full-cycle assessment of the cements’ impacts.

Head of sales, marketing and logistics Sanjay Wali said “We see GreenPro’s accreditation as a milestone in our journey to becoming carbon-negative by 2040. This also reaffirms our blended cement products’ green supremacy, which is accelerating the global transition from a grey to green reality.”
