The scrap metals market is a multi-billion-dollar global industry. Currently, total ferrous scrap supply rests below demand for construction steel where higher impurity tolerances facilitate scrap absorption. However, by 2100 forecasts suggest that total scrap supply will match 96% of total demand. This eventuality necessitates progress towards scrap sorting and processing improvements. Current inspection methods are based largely on visual inspection and inexpensive non-quantitative testing. Hand Held (HH) elemental analyzers hold promise to address the lack of quantitative evaluation in scrap processing. This research aims to study the flow of valuable elements in the scrap industry, and evaluate HH-XRF and LIBS systems for their potential worth. A description of unit strengths, limitations, accuracy, precision, and sensitivity will be presented both qualitatively and quantitatively. These analyzers will be evaluated based on their potential value-adds to the system and conditions for beneficial use in a dynamic market.
