Okaya and MISA together with TFe will lead the way in providing 100% Recycled Steel to the Industry with a fully sustainable business model. Structural steel is a premier green construction material High recycled content and recycling rate exceeds those of any other construction material in our industry Structural steel produced in the United States contains 93% recycled steel scrap, on average.As such, structural steel isn't just recycled but "multi-cycled," as it can be recycled over and over and over again. As the green building movement grows, more and more building owners, architects, engineers, and contractors are selecting structural steel framing systems to meet sustainable design and construction goals.The LEED Green Building Rating System, developed by the U.S. Green Building Council, has been crucial to this movement.
