JPMorgan’s 60‑storey tower at 270 Park Avenue in Midtown Manhattan now contains 2.2 million square feet of concrete that incorporates 29 million discarded glass bottles into its core.
Urban Mining Industries’ Pozzotive mix replaces 40% of Portland cement, cutting 5,000 tons of CO₂ and boosting the concrete’s compressive strength, according to data from Concrete Products magazine.
Fortunato Orlando of Severud Associates engineered the mix to meet early‑strength demands, ensuring floor‑by‑floor pouring stayed on schedule despite the low‑cement content.
AECOM’s Max Driscoll highlighted the project as the greenest skyscraper built in America, while Smyrna Ready Mix delivered thousands of truckloads of the custom concrete to the site.
The lighter glass‑based concrete reflects more sunlight, potentially lowering cooling loads and mitigating the urban heat island effect around the tower’s base.
City planners now plan to mandate ground‑glass pozzolan for new public rail and highway projects, extending the material’s reach beyond commercial real estate.
