Mining and cement have traditionally been seen by the media and public as carbon intensive industries. industry The cement manufacturing process typically involves burning fuels to heat a mixture of limestone (CaCO3) and additive materials to produce clinker, which in turn is mixed with gypsum to produce cement. The worldwide average emission factor for mercury from cement kilns has been reported as 35 mg/t cement (Renzoni et al. 2010). However,

The cement industry is no stranger to SKF and certainly not a factory with an annual production capacity of 2.3 million tons of clinker and 5.5 million tons of cement. This is one of the important cement factories in Turkey, in terms of production capacity and product variety, and we visit them regularly.
