There is plenty to talk about when it comes to manufacturing steel the industry faces criticism by others that actually want clear air and water.
As the world’s leading steel and mining company, our business operations extend from the mining of iron ore and coal to the production of the full range of steel products and services.
In 2015, we produced 73.7 million tonnes of iron ore and 6.29 million tonnes of coking coal, a form of carbonised coal burned in blast furnaces to melt iron. In the week ending February 25, 2017, (click here) domestic raw steel production was 1,770,000 net tons while the capability utilization rate was 74.7 percent. Production was 1,709,000 net tons in the week ending February 25, 2016 while the capability utilization then was 73.1 percent. The current week production represents a 3.6 percent increase from the same period in the previous year. Production for the week ending February 25, 2017 is up 0.2 percent from the previous week ending February 18, 2017 when production was 1,766,000 net tons and the rate of capability utilization was 74.6 percent. The industry is doing just fine. I am confident in the digital age there is significant efficiency added to these processes. There is no reason to FEEL SORRY for the industry as Republicans CHRONICALLY do to win votes. It is nonsense. These industries have been around for decades. I am confident they have no need for people to feel sorry for them or practice pandering politics. Accounting for a Sustainable Future, Research Brief, June 2014 (click here)
8 The environmental impact of steel production
Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes. The major environmental impacts from integrated steel mills are from coking and iron-making.
Virtually all of the greenhouse gas emissions associated with steel production are from the carbon dioxide emissions related to energy consumption.
Emissions to air
Coke production is one of the major pollution sources from steel production. Air emissions such as coke oven gas, naphthalene, ammonium compounds, crude light oil, sulfur and coke dust are released from coke ovens.
Emissions to water
Water emissions come from the water used to cool coke after it has finished baking. Quenching water becomes contaminated with coke breezes and other compounds. While the volume of contaminated water can be great, quenching water is fairly easy to reuse. Most pollutants can be removed by filtration.
Slag, the limestone and iron ore impurities collected at the top of the molten iron, make up the largest portion of iron-making by-products. Sulfur dioxide and hydrogen sulfide are volatized and captured in air emissions control equipment and the residual slag is sold to the construction industry. While this is not a pollution prevention technique, the solid waste does not reach landfills.
Gaseous emissions and metal dust are the most prominent sources of waste from electric arc furnaces.
The last thing any political leader should do is feel sorry for an industry. It inhibits innovation and invention. "Green Steel" - New Steelmaking Process Lowers Greenhouse Gas Emissions, Cuts Cost and Improves Quality May 13th of 2013 By James Ayre But now, (click here) a new process developed by researchers at MIT looks like it may be able to address this, greatly reducing the greenhouse gas emissions associated with steel production, while also lowering costs and improving the purity/quality of the steel. A “win, win, win” proposition, as the researchers put it.... There is absolutely no reason for political foot dragging in regard to pollution control and control of greenhouse gases. There are answers by some of the finest scientists in this country and the world. There is no reason to put off protections of Earth's climate OR cutting costs of steel production. There is no reason to separate the fact modern technology can do it all, improve quality, cut costs and lower emissions.
