The global metal recycling market, a significant player in the sustainability sector, is currently valued at approximately USD 4.7 billion. This robust industry is poised for further expansion, with experts projecting a staggering increase to USD 143 billion by 2036.
Driving this immense growth is the global move towards more sustainable economies and the increased demand for recycled metals. Metal recycling, being more cost-effective and environmentally sustainable, offers significant benefits over raw material sourcing, which can be energy and cost-intensive.
Despite the challenges posed by the post-COVID-19 slowdown in the manufacturing and construction industries, the recycled metal market has demonstrated remarkable resilience. This is a testament to the industry’s stability and potential for growth, even in the face of adversity.

Key Drivers Of The Metal Recycling Market Growth
Sustainability remains at the forefront of the metal recycling market growth. Other factors include:
- Environmental Regulation: Governments worldwide have enforced strict regulations mandating metal recycling to reduce landfill waste and minimise environmental degradation.
- Economic Incentives: Extracting and processing new raw metals is often more environmentally damaging and cost-intensive, making metal recycling a cheaper, more sustainable option for metal sourcing.
- Technological Advancements: The Catalyst for Metal Recycling Market Growth: Significant advancements have been made in metal recycling innovations, making the process more cost-effective and easier to unlock. Advanced sorting and recovery techniques enable higher yields and better-quality recycled metals, revolutionizing the industry.
- Steady Demand: While there has been a marked decline due to some industry stalling, the overall demand for recycled metals remains positive. The automotive, construction, energy and manufacturing industries remain dominant.
While each factor contributes significantly to the steady rise in demand for recycled metals, technological advancements in the sorting, collecting, and processing of recycled metals are the most prominent drivers.

Technological Advancements Of Scrap Metal Recycling in Australia
The metal recycling market industry in Australia has seen a significant boost in efficiency and precision, thanks to the introduction of Automated Sorting Systems. These systems have revolutionised the process of recycled metal recovery.
Modern recycling facilities have significantly increased the yield of recycled metals by using sensors and artificial intelligence to accurately separate them. These sophisticated systems automatically process recycled metals according to size, shape, and composition, ensuring more of the recycled metals are recovered.
1. Shredding and Granulating Equipment
High-capacity shredders and granulators break down recycled metals into more manageable parts. This process increases the recycled metals’ surface area, making them easier to handle when processing further.
2. Magnetic Separation
Magnetic separators automatically separate ferrous metals such as iron and steel from non-ferrous metals such as copper and aluminium. This technology improved the quality and value of the recycled metal yield.
3. Hydrometallurgical and Pyrometallurgical Processes
Particularly useful when recovering metals such as zinc and lead, hydrometallurgical and pyrometallurgical processes are advanced chemical processes used to metals from ores and recycled materials. Hydrometallurgical processes employ aqueous solutions to extract metal, while pyrometallurgical processes use high temperatures to melt and refine recycled metals.
