Researchers and industry have focused their attention on using alternative fuels in place of conventional fossil fuels (and so reducing the GHG emissions of the traditional manufacturing process), and developing alternative materials by partially replacing clinker used in cement systems with waste or by-products (Kajaste and Hurme, 2016).Clinker replacements that have been developed …

Cement manufacturing is an energy-intensive process due to the high temperatures required in thekilns for clinkerization. The use of alternative fuels to replace conventional fuels, in particularcoal, is a widespread practice and can contribute to improving the global warming impact andtotal environmental footprint of the cement industry.

Including a larger proportion of alternative constituents in cement (likely possible in the 15‑35% mass range – and potentially even up to 50%) reduces the quantity of clinker required as well as the process and energy-related CO 2 emissions associated with clinker production. Using newer alternative cement constituents, such as ground ...

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.. From 2014 to 2018, the clinker-to-cement ratio increased at an average of 1.6% per year, reaching an estimated 0.70 in 2018; this rise …

Cement kilns operate at temperatures at which steel would melt. That, combined with the length of time which fuels spend in the kiln, means that the process releases their energy while completely and safely consuming them. Alternative fuels have been successfully used in cement kilns for decades.

Cement manufacturing is an energy-intensive process due to the high temperatures required in the kilns for clinkerization. The use of alternative fuels to replace conventional fuels, in particular coal, is a widespread practice and can contribute to improving the global warming impact and total environmental footprint of the cement industry.

Holcim Philippines reported using more than 170,000 tons of waste materials last year as alternative fuel and raw material for its production. This translated to 38 days of avoiding coal in cement production, and therefore, lower carbon emissions from the company's operations.

Leimen (Germany) had percentage of alternative fuels about 50% and total costs of energy about 10 €/t. On the other hand, cement factories from Rustavi (Georgia) and Kaspi (Georgia) which did not use alternative fuels this year, had costs in value of . 32,61€/t and 28,9. 3€/t, respectively. Advantages of use of RDF as alternative fuel are

Due to the numerous possible sources of alternative fuels, the degree of variability in energy content, ash, moisture, particle size, form, density etc., extensive experience and know-how are necessary in order to identify the effect of co-processing on the clinker production process and, thus, offer the best solutions for the entire application of alternative fuels in the pyroprocess ...
