Cement is one of the most widely used substances on earth. Making cement is an energy and resource intensive process with both local and global environmental, health and safety impacts. Recognizing these facts, several cement companies, initiated the Cement Sustainability Initiative (CSI) as a member-sponsored program of the World Business Council

The cement industry alone accounts for approximately 4.1 % of EU's, and around 5 % of world's anthropogenic CO2 emissions (Mikulčić et al., 2013). In line with the EU commitment to combat climate change, the cement industry, as the third largest carbon emitting industrial sector in EU, needs a more sustainable future.

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 complied a comprehensive …

The required data are collected through direct investigation and interaction with workers.

mic chemical reactions makes the cement kiln process unstable. This means that achieving an ideal temperature profile through the kiln is essential to meet expectations on process stability and performance. Expert Optimizer can solve this problem. It has been applied to the cement kiln process more than 170 times in 15 years, achiev-

The European cement industry is committed to ensuring that society has sufficient cement to meet its needs, whilst at the same time reducing its fuel and raw material requirements and subsequent emissions. The use of waste materials in the cement industry, also referred to as co-processing, contributes towards achieving these objectives.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are ...

Salah M. El Haggar, in Environmental Solutions, 2005 Cement Industry. The cement industry is one of the main industries necessary for sustainable development. It can be considered the backbone for development. The main pollution source generated from cement industry is the solid waste called cement by-pass dust, which is collected from the bottom of the dust filter.

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions.

led to the Nigeria cement industry accounting for 63.6% of the West African region's cement output in 2011. Daily production is in excess of sales having recorded a zero importation from January 2012 to date and in the process of formalizing the exportation of cement to Eco- nomic Community of West African States (ECOWAS)

The cement industry produces about 10% of global human-made CO 2 emissions, of which 60% is from the chemical process, and 40% from burning fuel. A Chatham House study from 2018 estimates that the 4 billion tonnes of cement produced annually account for 8% of worldwide CO 2 emissions.

a new analysis of global process emissions from cement production. Global process emissions in 2018 were 1:50 0:12GtCO2, equivalent to about 4% of emissions from fossil fuels. Cumulative emissions from 1928 to 2018 were 38:3 2:4Gt CO2, 71% of which have …

The cement industry has made significant progress in reducing CO 2 emissions through improvements in process and efficiency, but further improvements are limited because CO 2 production is inherent to the basic process of calcinating limestone [3].

The cement manufacturing process consists of the following steps: Grinding and mixing of the raw materials. Burning of the mixture at a specified temperature for the correct duration. Grinding the consumed item called (clinker) along with gypsum. There are two methods available for the manufacture of cement: Wet Process.
