The Benchmarking and Energy Savings Tool (BEST) Cement is a process-based toolbased on commercially available efficiency technologies used anywhere in the worldapplicable to the cement industry. This version has been designed for use in China. Noactual cement facility with every single efficiency measure included in the benchmarkwill likely exist; however, the benchmark sets a reasonable standard by which to comparefor plants striving to be the best. The energy consumption of the benchmark facilitydiffers due to differences in processing at a given cement facility. The tool accounts formost of these variables and allows the user to adapt the model to operational variablesspecific for his/her cement facility.
