Energy Consumption in Production of Concrete

On average approximately 1 ton of concrete is produced each year for every human being in the world. Because of its abundance in the world market, understanding the environmental implications of concrete manufacturing is becoming increasingly important.

Typical cement plant power costs can range from EUR39 to EUR170/MWh. Mill designs. The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant.

When you average all cooling ton-hours and kilowatt-hours, you can achieve an average of less than 0.5 kw per ton. See my March 2006 HPAC Engineering article, “Ultraefficient All-Variable-Speed Chilled-Water Plants.” Also, see the table below. A 10-year-old retrofitted plant averaged below 0.55 kw per ton, for an energy savings of 50 percent.
