The cement industry burns scrap tires as fuel in kilns used to make clinker—a primary component of portland cement. A cement kiln is basically a large furnace in which limestone, clay, and shale are heated at extreme temperatures and a chemical reaction transforms them into clinker.
Materials like waste oils, plastics, waste tires and sewage sludge are often proposed as alternative fuels for the cement industry. Meat and bone meal are also considered now as alternative fuel [5]. Biomass waste and spent pot linings produced in aluminum smelters [6] are recently identified as potential alternative fuels for cement industry.
Cement manufacturing is a high energy consuming and highly polluting process. Cement producers are trying to reduce the energy and environmental costs by using alternative fuels and raw materials through their research and development. Alkaline environment, high temperature and long processing time allow cement kiln to burn a wide range of waste and hazardous materials.
Cement industry subsector require about 12% of total energy use in Malaysia and 15% in Iran, . It is observed that coal, fuel oils and petroleum coke are the major sources of energy needed in a cement manufacturing process. Recently natural gas, and alternative fuels found to be used by many cement industries around the world .

15 Iran's cement industry to prepare alternatives amid fuel shortage. 03 November 2021. Iran is facing the prospect of power shortages amid an insufficient supply of natural gas, according to Trend News. As a result, cement plants are expected to store mazut as an alternative fuel over the next few days, says the secretary of the Cement Industry ...
The Portland Cement Association (PCA) has been reporting alternative and waste fuel usage in the U.S. cement industry since 1977. During that period, the share of alternative and waste fuel usage has increased from minor amounts to 16 % of all fuel use in the cement industry in 2016.
These fuels need to have an appropriate chemical energy content which depends on the type of components and their organic content. An industry that is particularly well suited to the employment of alternative fuels is the cement industry. There are a number of factors that promote the use of alternative fuels in cement kilns.
Poland: Lafarge Poland has laid the foundation stone for the Euro100m new kiln line at its Małogoszcz cement plant. The replacement of the three existing kilns and installation of an alternative fuel (AF) line aims to reduce the plant's CO 2 emissions by 20% and its energy consumption by 33%. The company, a subsidiary of Switzerland-based Holcim, aims to make the cement plant into one of ...
Co-processing is the use of waste fuels as a source of energy and raw material [1]. This has already been practiced in the cement industry for a couple of decades. The clinker burning process offers excellent opportunities for the safe and sound recovery of a wide variety of AFR (alternative fuels …
2. Alternative fuel options for the cement industry Coal is the primary fuel burned in cement kiln s, however, the use alternative fuels in cement kilns is now common and increasi ng. The range of alternative fu els is extremely wide. They are usually available as gas, liquid and solid as shown in …

Written by Matt Drew, Saxlund International 31 March 2016 Cement production is one of the world's most fuel-intensive industries. Fossil fuels, mostly coal, have tended to be the industry's main power source, although increasingly, cement manufacturers are replacing up to 80% of their fossil fuels with more sustainable waste-derived fuels (WDF).
industry solvents, as well as tires, are often used as fuels in cement kilns as a replacement for more traditional fossil fuels (Gabbard 1990). The use of alternative fuels to displace coal reduces reliance on fossil fuels, reduces
The United States uses 15% alternative fuel in its kilns, according to the Portland Cement Association, a U.S. industry group. Spokesperson Mike Zande said its members have the capacity to catch ...
The main alternative fuels used in cement industry are residue oil and solvents, contaminated wood and process waste from wood, used tires and rubber waste, plastic waste, thermal fraction of domestic waste, sewage sludge, and animal meal.

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.
blending with mineral substitutes, and using lower-carbon alternative fuels to fire the kiln. Canada's 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 clinker-to-cement ratio and the use of alternative fuels is growing.
