The most widely used indicator to measure energy efficiency of cement plants is the specific energy use for the production of clinker (Ecofys et al., 2009, European Commission, 2013a, IEA, 2015, IEA-ETSAP, 2010, Worrell et al., 2007).There are several kiln types in operation worldwide for clinker manufacture with large differences in specific energy use and CO 2 …
Since 1950 the production of cement has gone up by a factor of 25, and China used more cement in 2011–2013 than the USA during the entire 20th century (Smil, 2013).Consequently, in 2010 the cement sector was responsible for 2823 million metric tons (Mt) of CO 2 emissions (OECD, 2012).This corresponded to almost 9% of global CO 2 emissions …
In industrial processess, cleaner production means increasing the efficiency of the use of raw materials and energy, preventing or replacing the use of hazardous and toxic materials, and reducing the amount and level of toxicity of all emissions and waste before leaving the process (Hoffman and Schmidt n.d., Jacquemin et al. 2012).In addition, there is a process …
Cement production contributes significantly to anthropogenic greenhouse gas emissions (GHG), a major contributor to global carbon emissions. The environmental impacts of cement production have grown in recent years and it is urgent to reduce its carbon footprint. Systems dynamics (SD) is a simulation method used to understand the nonlinear behavior of …
As a high-carbon and energy-intensive product, manufacturing cement, the key ingredient in concrete, takes a heavy toll on the climate. The Redding factory emitted about 282,000 tons of carbon dioxide in 2020 — equivalent to about 55,000 gas-powered cars.. Under pressure from state lawmakers, California's cement industry is gradually taking steps to reduce …
The cement industry, a major contributor to global greenhouse gas emissions, is a critical sector to address in order to achieve international climate goals and transition to a low-carbon future. Several key global initiatives and policies have been developed to drive carbon reduction in cement production.
The clean gas leaves the DeCONOx plant with a temperature of ~160 °C and is therefore ~ 30 [°C] warmer as the raw gas flowing into the DeCONOx. The clean gas is now fed to a tube …

The capture process is assumed to start with a flue gas condensation unit that aims to remove pollutants and cool down the gas stream to 30–40 °C. ... The cement industry in Europe is currently the second largest consumer of AF. Various roadmaps to decarbonize the sector have identified this as a critical measure to continue reducing the ...
Cement manufacturing contributed approximately 8% of global greenhouse gas (GHG) emissions in 2019 (Andrew, 2017).Reducing these emissions is particularly challenging since there are multiple and variable sources of CO 2 (approximately 50–60% of cement manufacturing GHG emissions are due to CO 2 released during the calcination reaction (part …
The cement industry faces a big challenge: meeting global infrastructure needs while reducing its impact on the environment. One effective way to do this is through carbon capture, a process that captures and removes carbon dioxide (CO 2) emitted during cement production.. Cement production is a major source of CO 2 emissions, responsible for about 8% of the world's total.
Book-and-claim systems for cement, which would decouple so-called green attributes like saved greenhouse gas emissions from the physical product (cement, in this case), tapping into carbon markets and other regulatory frameworks to finance low-carbon cement elsewhere. Adeleke of GCCA said his association's members have expressed interest in ...
However, different flue gas cleaning systems have to be used when initial SO2 emission levels are not very low. In cement industry, concentrations in the range of 50–400 mg/Nm3 (daily …
This has resulted in cement being largely a regional play with the industry divided into five main regions viz. north, south, west, east and the central region. The Southern region of India has the highest installed capacity of about 120.1 mtpa. An Indian Cement industry is: S No Second Largest Cement Market
Greenhouse gas emissions, especially CO2, have to be reduced by 50–80% by 2050, according to the IPCC [1].The type of fuel used in cement manufacture directly impacts on CO2 emissions, with coal ...

The magnitude of cement production leads to more than 7% of annual anthropogenic greenhouse gas (GHG) emissions, resulting from both energy use and chemical reactions, which imposes a notable ...
Bapat (2001) presented the application of electrostatic precipitators (ESP) for gas cleaning in cement industry for controlling the cement dust. Hindy (1997) also concluded that the application of ...
Cement industry has been always among the largest CO 2 emission sources. Almost 5–7% of global CO 2 emissions are caused by cement plants, while 900 kg CO 2 is emitted to the atmosphere for producing one ton of cement. In this work, global strategies and potentials toward mitigation of CO 2 emissions in cement plant have been discussed and the …
