Reuse and Recyclability of Steel

Steel plays a vital role in a circular economy where products and materials are kept in circulation at their highest use for as long as possible, and waste is minimised through processes like maintenance, reuse, refurbishment, remanufacturing and recycling.

Steel Reuse

Steel structures can be effectively designed for disassembly and reuse through features such as bolted or screw-fix connections. In some cases, steel can be reused without reprocessing, saving energy and resource use.

Recyclability of Steel

Steel is one of the most recycled materials globally. It is 100% recyclable and can be infinitely recycled without loss of quality. The recyclability of steel is enabled by its magnetic properties, allowing it to be easily separated and minimising the likelihood of it ending up in landfill. In Australia, 90%¹ of metals, including steel, are recovered for recycling.

Case Studies – Designed for Reuse

Western Sydney Stadium

Western Sydney Stadium features a steel structure optimised for disassembly, enabling future re-use. Unlike welded structures, its components can be unbolted, facilitating disassembly, relocation and reuse in the future. By incorporating design for disassembly, steel can contribute to circularity by reducing material consumption and enhancing resource efficiency.

COVID-19 Surge Centre

Light gauge steel frames made from TRUECORE® steel were used in nearly all the framing for the construction of the COVID-19 surge centre, utilising offsite prefabrication. Almost the entire structure was engineered to be flat-packed and relocated, enabling it to be re-established at a different location.
