Structural steel produced in the United States contains 93% recycled steel scrap, on average. At the end of a building's life, 98% of all structural steel is recycled back into new steel products, with no loss of its physical properties. As such, structural steel isn't just recycled but "multi-cycled," as it can be recycled over and over and over again.
Any waste material produced during the fabrication phase, e.g. off-cuts, swarfe, can be recycled and used again in the steelmaking process. Off-site manufacture is more efficient, faster, leaner and safer than site construction.
