Can We Make Steel Without Coal? Coal Action

World steel production in 2011 was 1518 Mt and used 761 Mt of coal 12% of all hard coal mined. The Glenbrook plant (now owned by Bluescope) makes 600-650,000 tpy steel and uses 750,000 tpy Huntly coal plus 1,000 GWh electricity and some Natural Gas, supplying 90% of NZ’s needs. It also recycles steel. Can we make steel with less coal?

(PDF) Use of alternative fuels in cement industry

Cement production depends mainly on coal as energy source, however, alternative fuels such as biomass and hazard wastes have increasing utilization ratios. The utilization of alternative fuels in the cement industry since the 1980s was driven by rising energy prices, depletion of fossil fuels and the environmental impact of traditional fuels combustion [8, 10] .

What Are the Uses of Coal? Reference

According to the World Coal Association, the primary uses of coal are in electricity generation, the creation of liquid fuel, the production of steel and cement manufacturing. There are two primary types of coal, thermal coal and metallurgical coal.

What is Cement Clinker? Composition, Types &

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color.

The cement industry is the most energy intensive

Cement is also unique in its heavy reliance on coal and petroleum coke.
