Recycling Metallurgy: Recovering Value Without Losing Control
Explain sorting, remelting, refining and contamination control in circular metal systems.

Scrap is a variable feedstock
Composition, coatings, attachments and contamination vary more than primary material inputs.
Sorting creates value
Identification and separation preserve alloy families and prevent dilution by harmful elements.
Remelting is not enough
Some elements oxidise or can be removed; others accumulate and require dilution or specialised refining.
Quality and yield
Oxidation loss, dross, tramp elements and energy use determine whether a recycling route is technically and economically credible.
Engineering takeaway
Design alloys, products and collection systems together so recovered material retains high-value applications.
