Steel global consumption

In 1973, global consumption of nickel was 660,000 tons and that of the United States 235,000 tons (Sevin 1980). End uses of nickel in the United States in 1973 were transportation (21%), chemicals (15%), electrical goods (13%), fabricated metal products (10%), petroleum (9%), construction (9%), machinery (7%), and household appliances (7% IARC 1976). A similar pattern was evident for 1985 (Table 6.3). In 1988, 40% of all nickel intermediate products consumed was in the production of steel 21% was in alloys, 17% in electroplating, and 12% in super alloys (USPHS 1993). The pattern for 1985 was similar (Table 6.3). In Canada, nickel is the fourth most important mineral commodity behind copper, zinc, and gold. In 1990, Canada produced 197,000 tons of nickel worth 2.02 billion dollars and was the second largest global producer of that metal (Chau and Kulikovsky-Cordeiro 1995). Most of the nickel used in the United States is imported from Canada and secondarily from Australia and New Caledonia (USPHS 1977). 

Worldwide plastics consumption is of the order of 170 million tonnes annually in round figures, with a turnover of US 560 billion. Over the past five years, global plastics consumption has grown consistently by an average annual rate of 4%, comparable with steel and aluminium rates. 

The annual global production of concrete has been reported to be second to water consumption by mankind. It is estimated that current consumption of concrete in the world is of the order of 11 billion metric tons every year. Also, about 10% of global production of steel goes to reinforced concrete applications. ... 

About 70% of natural rubber consumption goes into tire production while the remaining 30% is used by the nontire sector. There is some substitutability of various synthetic elastomers for natural rubber, but it is rather limited. This substitutability is restricted for the tire sector, which globally uses almost half of its total rubber requirement as natural rubber. In the short term, it is technically very difHcult to make major substitutions of synthetic rubber for NR use. Some applications are very critical, such as the use of NR in wire adhesion compounds for the production of steel-belted radial tires. Also, the use of natural rubber is very critical in the production of very large off-the-road tires. However, the natural rubber requirements of the nontire sector were only 29% of its total rubber usage in the year 2000. The nontire sector only used about 22% of its total rubber requirement as natural rubber in 2010. Many times it is easier in the nontire sector to substitute specialty syn-...
