The Environmental Impact Of the Cement Industry. Cement primarily uses limestone and clay for the manufacturing process. It releases carbon dioxide, Sulphur dioxide, and nitrogen oxides as the by-product. Dust, smoke (smog), and other elements are also responsible. These lead to a wide array of issues, some of these are:
Finally, a normalisation, using Western Europe yearly emissions is performed and permits to highlight among all the CML01 indicators which ones are the main impacts for the cement production. Abiotic depletion, global warming, acidification and marine ecotoxicity are the four identified impacts. Introduction
Cement emits high levels of carbon dioxide due to the very nature of its manufacturing process (limestone decarbonation). It can, however, improve its environmental balance, firstly in terms of energy efficiency.
Utilization of cement as building material is gaining more importance. Cement industries around the world are contributing in global and as well as local pollution. In Pakistan most of the cement industries are constructed in remote areas without any proper environ
Cement production is a carbon-intensive process. It causes up to 5 % of global greenhouse gas emissions to the environment during the calcination process and burning of fossil fuels [42, 43]....

The study indicates that perhaps 43 percent of the carbon dioxide a given volume of cement released into the air during manufacture is being soaked up again over time." However, this is far from the only way in which concrete …
On the other hand, the cement industry is one of the most significant contributors to air pollution[1]. The cement industry contributes to around 7% of global carbon emissions. Particulate matter (PM) emissions from cement plants are very high, and cement is understood to be the most severe pollutant in the world.
Manufacturing portland cement accounts for approximately 5% of the anthropogenic CO 2 emissions worldwide and about 2% of total CO 2 emissions in the U.S. As construction materials go, cement production is one of the largest CO 2 emitters.
Approach of using industrial waste as supplementary cementitious material or cement free concrete also would reduce dependency on cement demand. Success in utilizing …
Cement industry is potential anthropogenic source of air pollution. production originates about 5% of global manmade CO2 emissions. The typical gaseous emissions to air from cement production include NOx, SOx, CO, CO2, H2S, VOCs, dioxins, furans and particulate matters. These major pollutants can be classified in two categories-
One of the major problems is emission of CO2 from the Cement industry. It is found that world yearly 1.6 billion tons production of cement covers 7% of carbon dioxide's yearly production. As CO2 is harmful for human health and also for the wild life. It causes many respiratory problems like asthma, bronchitis, and nasal infections.
The aggregates are sourced from a local body of water and crushed in a natural procedure. That process releases nearly no carbon emissions, the cement is the true problem …
Environmental Impact Assessment is a very exhaustive study that is required to be done to assess the possible positive or negative impact that a proposed project may have on the environment. EIA studies include environmental, social and economic aspects. This article specifically discusses the EIA studies on cement Industry.
CEMENT INDUSTRY 1 Introduction to EIA Environmental Impact Assessment is a tool designed to identify and predict the impact of a project on the bio-geophysical environment and on man's health and well-being, to interpret and communicate information about the impact, to analyze site and process alternatives and provide

This liquid mix does not differ much in process and result from the dry mixture but it does have a positive impact environmentally. This comes in the form of a reduction of carbon footprint. Due to the liquid state, the mixture can …
Cement production also produces a high amount of CO 2, accounting for almost 5% of the world’s anthropogenic CO 2 emissions. 7 Approximately 337 billion tons of carbon have been emitted through cement production and the burning …
Although the factors differ from country to country and cannot be generalized, there are major concerns regarding shortage of raw materials, GHG emissions, dependence on fossil fuels and lack of investment in technological innovations. For the cement sector, key points for an environment-friendly industry are use of alternative raw materials …
Cement manufacture causes environmental impacts at all stages of the process. These include emissions of airborne pollution in the form of dust and gases; noise and …
As regard to as the environmental and social criteria, the study considers the impact categories listed in Table 1: their values refer to the production of 1 Mg of cement. According to the standard EN 15804 [ 29 ], these categories describe environmental impacts, resource use, and waste categories related to a production.
According to Chatham House, cement is the source of about 8% of the world's carbon dioxide (CO2) emissions. To put that into perspective, if the cement industry was a country, it would be the third largest emitter in the world. It contributes more CO2 than aviation fuel and isn't far behind the global agriculture business.
rapid economic growth has increased cement production in the construction industry sector, thus causing problems to the environment [4]. …
China is by far the richest country in Cement Industries and also the major source of carbon emission. In 2015, 4% of the Carbon emission belonged to the Cement industries caused by their special ingredient called …
This "environmental map of cement production" is not definitive since there is a great variability of processes, raw-materials and plant design; however, it can be useful to better understand the impact of cement fabrication on environmental issues. Figure 3 shows a schematic diagram (environmental map) describing the preparation of cement ...
Sulfur dioxide (SO 2) in high concentrations can affect breathing and may aggravate existing respiratory and cardiovascular disease. Sensitive populations include asthmatics, individuals with bronchitis or emphysema, children, and the elderly. SO 2 is also a primary contributor to acid deposition, or acid rain.
Certainly, the level, intensity, and effects of pollution from these cement factories on the environment and on human health will equally vary. These impurities pollute aqueducts and other water sources resulting in water-related illnesses. Wastes from the cement industries are indiscriminately disposed causing serious pollution to the environment.

The amount of CO2 emitted by the cement industry is nearly 900kg of CO2 for every 1000kg of cement produced. Newly developed cement types from Novacem and Eco-cement can absorb carbon dioxide from ambient air …
How does cement affect the environment? The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth, the topsoil. Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding.
3.2 Environmental effect due to cement manufacturing process Emissions to air is the main environmental challenge faced by the cement industry. Main pollutions of cement productions include; cement dust, air pollution, water pollution, solid waste pollution noise pollution, ground vibration and resources depletion due to raw material extraction.
