The Indian cement industry with a total capacity of 151.2 million tonnes (including mini plants) in March 2003 has emerged as the second largest market after China, surpassing developed nations like the USA and Japan. Per capita consumption has increased from 28 kg in 1980-81 to 110 kg in 2003-04. In relative terms, India’s average consumption
As presented in Table 3, the specific capital investment costs for cement plants with carbon capture are higher than for the cement plant without carbon capture (benchmark case) by about 112% for Case 2 and about 75% for Case 3. The calcium looping technology shows significantly lower investment costs than the gas-liquid absorption design due to higher energy efficiency
