New York used 29 million glass bottles in concrete for JPMorgan’s 60-storey HQ

A massive skyscraper rising in Midtown Manhattan has turned tens of millions of used waste bottles into part of its structural support. The project shows how city waste can replace carbon-heavy building materials on a large commercial scale. Workers used special concrete containing ground recycled glass in the foundation and floor slabs of JPMorgan Chase's new 60-storey headquarters at 270 Park Avenue. By replacing 40 per cent of traditional Portland cement with ground-glass pozzolan, the project kept 29 million discarded bottles out of landfills while also strengthening the concrete. The change saved more than 5,000 tons of carbon dioxide emissions during construction. Traditional cement production uses energy-intensive kilns that release large amounts of greenhouse gases, making concrete one of the main sources of industrial emissions worldwide.
