Quicklime; hydrated lime; carbonation; carbon dioxide; carbon sink 1. Introduction The process emissions of lime production, i.e. the CO 2 released during limestone calcination excluding that released from the combustion of fossil fuels, are esti-mated to account for about 1% of the global anthro-pogenic CO 2 emissions excluding driven off limestone to leave so-called quicklime. The quicklime descends through the cooling zone and is discharged at the base of the kiln. Obviously, various air pollutants are generated during combustion of fuels in the kiln. Hydrated lime is made by adding water to crushed or ground quicklime and thoroughly mixing theEMEP/EEA air pollutant emission inventory guidebook

Calculating CO2 Emissions from the Production of Lime,
which limestone, which is mostly calcium carbonate (CaCO 3) is heated in a kiln to produce quick lime (CaO). Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere. However, some facilities recover a portion of the emissions- e.g. for use in sugar refining and precipitated calcium carbonate production.produced for calcitic limestone). These estimates are theoretical, based on the production of two moles of CO 2 for each mole of limestone produced. In some facilities a portion of the CO 2 generated is recovered for use in sugar refining. In sugar refining, a suspension of hydrated lime in water is used to adjust the pH of the product11.17 Lime Manufacturing US EPA

Lime Market Size, Share & Growth Global Report [2022-2029]
The global lime market size was valued at USD 40.07 billion in 2021. The market is projected to grow from USD 40.94 billion in 2022 to USD 49.17 billion by 2029, exhibiting a CAGR of 2.7% during the forecast period. The global COVID-19 pandemic has been unprecedented and staggering, with experiencing lower-than-anticipated demand across Here, existing data on materials associated with the production, utilisation, and disposal stages of lime -containing materials Similar to cement, lime is mainly produced via the heating of limestone (CaCO 3) in a kiln at temperatures of 900 ±1200 C°.

3.3.7 Shaft kiln (production of lime) Similar to cement clinker, lime is produced by the calcination of limestone, resulting in 0.79 tCO 2 /t Lime process-related emissions [ 77]. While rotary kilns can be used, the more energy efficient shaft furnaces dominate in Europe.The emission of pollutants that were not measured was estimated from literature. The life cycle inventory of KFN is described in Ecoinvent report No.7 (Kellenberger et al., 2007) that only considers the information related to the production of hydrated lime and not the information regarding the production of milled and raw limestone products.Evaluation of the environmental performance of lime production
