I wonder what Henry Bessemer would think of steel-making today? Since he developed the first inexpensive process for the mass production of steel in the 1850s, the world has progressed to produce over 1,606 million tonnes in 2013.
The great thing about steel is that it is 100 per cent recyclable – to the same quality, time and time again. There’s also some important energy and raw material savings. Figures from the World Steel Association show that more than 1,400 kg of iron ore, 740 kg of coal, and 120 kg of limestone are saved for every tonne of steel scrap made into new steel.
