It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
