The EU cement industry already uses more than 40% fuels derived from waste and biomass in supplying the thermal energy to the grey clinker making process. Although the choice for this socalled alternative fuels (AF) is typically cost driven, other factors are becoming more important. Use of alternative fuels provides benefits for both society and the company: CO
· The cement industry is one of the highest energyintensive industries in the world, with fuel and energy costs typically representing 3040% of total production costs. On an average, the specific electrical energy consumption typically ranges between 90 and 130 kWh per tonne of cement. Keeping in view the huge energy demand of the cement industry, the Saudi Arabian government has been .
Energy intensity in Indian cement industries is a matter of concern given the high import burden of crude petroleum. Concerns have been reinvigorated by the global and local environmental problems caused by the everincreasing use of fossil fuels, and so it is clearly an enormous challenge to fuel economic growth in an environmentally sustainable way. In this context, this paper has analyzed ...

In all recent works, after performing an energy audit, Energy Department, Institute of Science, High Technology Environmental sciences, Graduate University of Advanced Technology, Kerman, Iran ABSTRACT Industrial energy consumption lies between 30% and 70% of .
The cement industry is known to be the largest consumer of energy and natural resources. Globally, an average of a ton of cement is needed by every individual each year.
· Getting the Numbers Right (GNR) is an independently managed database of CO2 and energy performance information on the global cement industry. Through the database, all participating companies and interested stakeholders can access standard, Webbased reports. The database's administrators also answer individual queries about specific issues within strict confidentiality guidelines.
energy and environmental improvements can be achieved with contracted formal energy audits. Changes in product formulation also offer significant nearterm energy and environmental improvements. Longerterm improvements could come from advanced research and development programs. However the cement industry, like most of the commodity materials
· The cement plant of the future achieves considerably lower operating costs and higher asset value through higher energy efficiency, yield, and throughput. More targeted and effective maintenance lengthens the lifetime of equipment. Each plant's environmental footprint is minimized, securing its license to operate across loions and jurisdictions. The plant meets customer demand .

Cement Industry Introduction. Cement is a rocky powder that can be mixed with water and molded to any desired shape, after which it hardens to a rocklike consistency. It is used worldwide both as a mortar to join bricks and blocks together and as an ingredient of concrete, which is mixture of crushed rock, sand, and cement that is used to ...
Cement accounts for 83% of total energy use in the production of nonmetallic minerals and 94% of C02 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement contains 95% cement clinker'3'. Large amounts of ...

· Cement manufacturing is highly energy and emissionsintensive because of the extreme heat required to produce it. Producing a ton of cement requires million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to ...
Cement industry power solutions . Cement production is an energyintensive process, but the industry has boosted efficiency in recent years by investing in power plants that use the dry process of cement manufacture and phasing out more energyintensive wet process operations. Even using the dry process, the energy input needed to make one ton ...
· The cement sector is the thirdlargest industrial energy consumer and the secondlargest industrial CO2 emitter globally. Rising global population and urbanisation patterns, coupled with infrastructure development needs, drive up the demand for cement and concrete and increase pressure to accelerate action in reducing the carbon footprint of cement production.
Cement accounts for at least 5 percent of anthropogenic emissions of greenhouse gases, and, according to some estimates, this share may be even higher. At the same time, energyrelated expenses in the cement sector, mostly on fossil fuels and electricity, account for 30 to 40 percent of the industry's cash costs. While current energy
· According to the International Energy Agency, the cement industry accounts for about seven per cent of total global CO2 emissions. The industry's production methods require a high heat level and consequently a high energy demand.
