The first major use of alternative fuels in the cement manufacturing industry emerged during the mid-1980s. The primary goal in substituting fossil fuels was to enable the industry to remain economically competitive, as fuel consumption accounts for almost one-third of the cost of producing clinker. Any positive impact on the environment was considered an added benefit.
The waste used by cement plants as alternative fuel can be classified into five broad categories, which generally are associated with specific regulations and/or implementation constraints related to the materials:
Both research and international experience suggest that no single alternative fuel can, by itself, meet the entire thermal demand of cement manufacturing. However, a mix of different alternative fuels can achieve that goal.
