Efficiency and profitability in scrap metal recycling can only be realised if the sorting process is fast, accurate, and reliable. Unfortunately, advancements in product development have not made things any easier for scrap metal recyclers due to the rise of alloy-based products. Most metallic products nowadays use a mixture of different materials and metal. Notably, sorting these products during recycling is both challenging and time-consuming. Besides, the equipment used by scrap metal recyclers might not be reliable for analysing highly mixed products.
