Nowadays, the steel industry is on the edge of a major technological evolution to deal with the huge amounts of CO 2 produced in the conventional steelmaking process. The use of blast furnaces and basic oxygen furnace produces around 1.8 ton of CO 2 per ton of steel produced. [6]

Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
The provinces subjected to the grande gabelle had to pay for salt at an official price and were also required to purchase a fixed amount annually, while in other areas, no taxes were paid at all. As a result, in the 18th century, the price of salt in Paris was 20 times higher than its price in Brittany, encouraging smuggling between regions.
The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion.
