Cement industry is one of the17 most polluting industries listed by central pollution control board in india. during the last decades, the emission of dust from cement factories has been increasing alarmingly due to expansion of more cement plants to meet the growing requirement of cement materials for construction of buildings.
+The cement subsector consumes approximately 12–15 of the total industrial energy use. therefore, this subsector releases co 2 emissions to the atmosphere as a result of burning fossil fuels to produce energy needed for the cement manufacturing process. the cement industry contributes about 7 of the total worldwide co 2 emissions. this study.
Key words: cement, cement industry, emissions. introduction. concrete is the most common construction material used in building industry. cement is a basic component of concrete used for building and civil engineering construction. on average approximately 1 ton of concrete is produced each year for every human being in the world. therefore.

The cement industry recognizes its responsibility to manage the environmental impact, associated with the manufacturing of its product. mainly, there are two types of cement production process; such as wet process and dry process. the preparation of cement includes mining, crushing, and grinding of raw materials, calcining the materials in 1408.
The sustainability of concrete construction is the first challenge facing the industry. concrete solutions are often the most sustainable and have the potential for a very long service life, but because concrete is used in vast quantities, its use does have a global impact. figure 1: production of cement in 2016.
The uk cement industry has agreed to reduce its primary energy consumption by 25.6 per tonne of cement produced by 2010, from a 1990 baseline. in return, the industry receives an 80 rebate from the climate change levy. the reductions are phased over a number of years (table 2.2.1) mineral profile: cement raw materials 2: extraction and processing.
Thus the starting point of the establishment of the cement industry took place without the proper analysis of the demand and supply of cement for the country. within the span of the next 2 to 3 years, the supply of cement coming into the country faced an expanded capacity of the product.
