AISC Releases Buy Clean Guidance to Help Legislators Maximize Structural Steel’s Unmatched Sustainability
CHICAGO - Hot-rolled structural steel is the greenest structural material on the market, thanks to its unsurpassed recycled content and ability to be recycled into new steel, over and over again, with no loss of properties. It's an obvious choice for the Buy Clean movement, which advocates for environmental properties that encourage the use of products and materials with a smaller carbon footprint. But the industry is complex. That's why the American Institute of Steel Construction has rel...
Transbay Study Group Makes Recommendations
CHICAGO - The American Institute of Steel Construction’s ad hoc task group on Transbay has wrapped up its work and made its recommendations to the AISC Committee on Specifications.

Why Precast Is Central to Cutting Concrete's Carbon Footprint
With the ability to cut CO2 footprint by 25% factory-based precast concrete production has the potential to save billions of tons of CO2 being emitted each year. So why is it so overlooked, asks Mats Jungar, CEO of Elematic? The world has a love-hate relationship with concrete. On the positive side the raw materials for concrete are plentiful, and the production of concrete foundations and structures are extremely cheap. But on the negative side concrete’s contribution to global CO2 o...
