Alternative fuels are one of the important fuel sources in cement industry.
A lower carbon intensity than coal or petcoke. According to the International Energy Association, these mixed fuels can be 20 to 25% less carbon-intensive than traditional fossil fuels. Using alternatives to coal and petcoke as replacement fuels in a cement kiln can significantly reduce greenhouse gas emissions, and in some cases other air pollutants.
We aim to reduce the dependency on natural resources and fossil fuels by supporting alternative fuel usage.
The use of alternative fuels in the cement industry has been growing rapidly, not only due to the need to find responsible ways to dispose of these materials but also to their economic advantages. Kiln fuel typically represents approximately 25% of clinker production costs, alternative fuels often cost much less and can even command a gate fee (negative cost).
The process of clinker production in kiln systems creates favourable conditions for use of alternative fuels. These include high temperatures, long residence times, an oxidising atmosphere, alkaline environment, ash retention in clinker, and high thermal inertia. These conditions ensure that the fuel’s organic component is combusted and the inorganic part, including heavy metals is trapped and combined in the product.
