Using alternative fuels in cement manufacturing is recognized for farreaching environmental benefits (CEMBUREAU 1999). The embodied energy in alternative fuels that is harnessed by cement plants is the most direct benefit, as it replaces demand for fossil fuels like coal.
for cement plants to derive 2070% of their energy needs from alternative fuels (Portland Cement Association 2006). In the US, as of 2006, 16 cement plants were burning waste oil, 40 were burning scrap tires, and still others were burning solvents, nonrecyclable plastics and other materials (Portland Cement Association 2006).
#0183;#32;Depending on the cement plant''s location, some alternative fuels may be more favourable than others; important issues are for instance transport costs and the availability of the fuel. First, the reference case was calculated,, 12 500 and 1500 kg/h petcoke as primary and secondary fuel, respectively.
#0183;#32;The main advantages of using Alternative Fuels in the Cement Industry are economic and environmental. Cement producers strive to reduce their production costs. Fuel accounts for 20 to 25% of the production cost of cement and one viable option is the use of alternative fuels at a much lower cost than conventional fossil fuels.
Alternative fuels are another source of energy used by cement producers around the world. They can replace the basic sources of energy used by cement kilns to produce the high temperatures that
reduction in cement production costs is also expected. Varying amounts of different alternative fuels have been studied in this thesis and referred to an actual cement plant in Ethiopia, located in the northern province of Mekelle. The availability of alternative fuels in the region has been estimated.
#0183;#32;Employing alternative fuels in cement plants is an important element of a sound waste management policy. This practice promotes a vigorous and thriving materials recovery and recycling industry (Cembureau, 1999). Key considerations for coprocessing alternative fuels.

#0183;#32;The use of alternative fuels in cement manufacture is also ecologically beneficial, for two reasons: the conservation of nonrenewable resources, and the reduction of waste disposal requirements
Global CemFuels provides information on alternative fuels for the global cement and lime industry. Alternative fuels for the cement and lime industries include refusederived fuel (RDF), municipal solid waste (MSW), chipped tyres and whole tyres, biomass, sawdust and many other wastes and coproducts that can be used as fuels in the cement and lime industries.
Cement manufacturing is a high energy consuming and heavy polluting process. To reduce the energy and environmental costs cement producers are currently using a blend of alternative fuels with
blending with mineral substitutes, and using lowercarbon alternative fuels to fire the kiln. Canadas cement industry has made progress over past two decades in each of these areas. Energy intensity improved by 21% between 1990 and 2010. There have also been improvements in the clinkertocement ratio and the use of alternative fuels is growing.

Experience from cement plants using high substitution rates of alternative fuels provides some rules of thumb as an orientation. For instance, the specific energy consumption of a fourstage double string preheater kiln (~2800t/day) increased by up to 15% while raising the substitution rate from 0% to 75%.

using alternative fuels in substitution for conventional fuels. Regulatory controls over cement plants in different countries were found to vary significantly, with the regulatory bodies in some countries requiring much lower emission levels of certain pollutants than did those in other countries.
This study has shown that several cement plants have replaced part of the fossil fuel used by alternative fuels, such waste recovered fuels. Many years of industrial experience have shown that the...
