    Improving the sustainability of the cement industry is an important challenge and is mainly focused on lessening CO2 emissions in the USA To reduce CO2 emissions, cement manufacturers are increasingly developing alternatives to traditional clinker development: These include 1) clinker replacement by ground granulated blast– furnace slag and fly ash, and 2) the importation of clinker from“For equipment unique to the cement industry, such as the kiln and grinding media, you need a customised solution In this area, equipment suppliers have the potential to develop industry specific solutions that will generate max value In contrast, a stacker reclaimer is common in many industries and there are already many solutions available In general, there are enough frameworksIndustry 40 The path to revolutionise cementThe US cement industry is comprised of 106 cement plants (99 clinkerproducing plants and 7 grinding facilities) operating just under 100 mmt of clinker capacity and roughly 126 mmt of finish grinding capability annually The 2013 plant survey reflects the industry emerging from the economic downturn as total capacity is 37 mmt less than the 2010 plant summary and 19 kilns totaling 57 mmtUS Portland Cement Industry: Plant Information Summary
