Abstract:
A system for forming a recycled metal product from at least one metal scrap feedstock source, wherein the at least one metal scrap feedstock source contains at least one contaminant, comprising:establishing a maximum weight percentage of the at least one contaminant in the recycled metal product; determining the weight percentage of the at least one contaminant which is present in the at least one metal scrap feedstock source; determining whether the weight percentage of the at least one contaminant which is present in the at least one metal scrap feedstock source will exceed the established maximum weight percentage of the at least one contaminant in the recycled metal product; and if the weight percentage of the at least one contaminant which is present in the at least one metal scrap feedstock source will exceed the established maximum weight percentage of the at least one contaminant in the recycled metal product, then combining the at least one metal scrap feedstock source with at least one other metal scrap feedstock source so as to cause the combined metal scrap feedstock sources to have a weight percentage of the at least one contaminant which is present in the combined metal scrap feedstock sources to not exceed the established maximum weight percentage of the at least one contaminant in the recycled metal product.
