Steel is an alloy made up principally of iron and carbon.
Steel is an alloy made up principally of iron and carbon. The oldest archaeological remains date back to 3000 B.C. It is believed that the first steel alloys were produced around 1400 B.C. In 1902, the metallurgical engineer Paul Héroult designed an electric oven which became used to melt steel, separating it from scrap. Its use is growing everyday worldwide. In 2010 the production of steel was 1280 million tons, 40% of which was produced from scrap…and what if there was no recycling?
Recycling is creation.
