Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace.Pig iron has a high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it brittle and not useful directly as a material except for limited applications.
The only part of the process that couldn't be made entirely renewable is obtaining the initial metal bearing ore, which must be mined. And even then, steel is infinitely recyclable, and nearly 70% of of new steel products produce each year are sourced from from scrap metal instead of fresh ore. –
Uranium is a chemical element with the symbol U and atomic number 92.
