The most common example of feedstock recycling in Europe is currently the use of plastic waste in blast furnaces, where plastics are gasified into syngas and replace coke, coal or natural gas to act as a reducing agent to convert iron ore and other oxidised metals into pure metals.
The steel industry has been actively recycling for more than 150 years, in large part because it is economically advantageous to do so. It is cheaper to recycle steel than to mine iron ore and manipulate it through the production process to form new steel.
Jun 25, 2019· Steel and iron are the most recycled materials in the world due in part to the opportunity to recover large structures as well as the ease of reprocessing. The use of magnets in the sorting process enables recyclers to easily separate them from the mixed waste stream. Every year, around 400 million tons of metal are recycled worldwide.

Because of its physical, chemical and mineralogical properties, it can be used as a raw material in a process like sintering. The mill scale contains high amounts of Fe and low amounts of silica and alumina. Thus, recycling it through the sintering process helps in the saving of raw materials like iron ore .
Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota. Creating steel from low-grade iron ore requires a long process of mining, crushing,
Available world iron ore resources. Iron is the most abundant element on earth but not in the crust. [citation needed] The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.

The hardness of the waste rock is determined by the rock type. For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense.
