Reducing water use starts with understanding the major uses of water in steel plants. Facilities use water in ways that both directly and indirectly support production, some of which lend themselves more or less readily to water use reduction efforts. Below, we have summarized the major types of water usage within steel plants and highlighted ...

Fig. 3 shows steel demand in China from 2015 to 2050 under the BAU and carbon-neutrality scenarios. Under the BAU scenario, steel demand increases from 803.83 million tons (Mt) in 2015, peaks at 1064.77 Mt in 2020, and decreases to 756.09 Mt in 2050. It can be observed that construction and machinery are the two major steel consumption …
