Structural steel is considered to be a premier green construction material, because its high recycled content and recycling rate exceed those of any other construction material. The steel industry has undergone a tremendous effort to reduce greenhouse gas and overall emissions by 36% and increased the water recycling rate of steel production to 95%. The industry has been proactive in pursuing measures that typically exceed regulatory requirements.
As the green building movement grows, more and more Montana building owners, architects, engineers, and contractors are selecting structural steel framing systems to meet sustainable design and construction goals. And under LEED 2009 and V4 criteria, structural steel receives maximum credit for its contribution to the overall structure rating , due in large part to its recycled content, recycling rate, and transparency.
How about the future? At the end of a building’s life, 98% of all structural steel is able to be recycled back into new steel products, without losing physical properties. As such, structural steel isn’t just recycled but “multi-cycled,” as it can be recycled over and over and over again. It is truly a cradle-to-cradle material.
