  • Utilisation of waste marble powder in cement industry

    Presently large amounts of slurry are generated in marble cutting plants with serious consequences on the environment and humans. This paper presents test results showing the feasibility of using waste marble powder (WMP) in cement industry as a substitute limestone. Also, it describes the formulation of new lime–based (CR II) cementitious materials derived from these industrial wastes. The ...

  • A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source

    The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...

  • Global solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Cementing the PC MACT

    On September 9, 2010, the U.S. EPA promulgated the final amendments to the National Emissions Standard for Hazardous Air Pollutants from Portland Cement Manufacturing Industry (40 CFR 63 Subpart LLL), also known as the PC MACT. EPA’s self-proclaimed “historic” rulemaking includes some important implications for cement manufacturers and other sources that may be subject to ...

  • Air pollution control through kiln recycling by-pass dust in a cement factory

    Over the centuries, air pollution has increased from a local nuisance to a global problem (Emberlin 1998). Cement industry is one of the most important and strategic industries in Iran. However, its air pollution has been a serious problem. The primary related pollution is dust, which industrial countries have allocated tremendous efforts in reducing its volume. Dust in different stages of a ...

  • Assessment of raw materials for cement industry in Sohag area, upper Egypt

    In the last few years, cement industry become a major player in materials recycling, although it is environmental polluted industry and a great consumer of limestone and clay. Cement manufacturing depends greatly upon chemical and physical characteristics of raw materials, its quality and quantity, simplicity of its extraction and its costs. Sohag Governorate is surrounded by the Eocene ...

  • Environmental assessment of the cement and concrete life cycle in Greece

    The basic targets of the modern cement and concrete production industry are the reduction of energy costs and minimisation of environmental effects. Life Cycle Assessment (LCA) is a useful tool for the evaluation of the environmental performance of a production system. The objective of this work is to provide a very clear analysis and quantification of all the parameters of the process that make ...

  • Cement Manufacturing - Balancing Growth with Air Quality Requirements

    In most areas of the U.S., it appears that the recession is a bad memory and the signs of recovery are all around us. As described by the Portland Cement Association (PCA) on its website[1], “following the strongest cement consumption gains in seven (7) years in 2012, cement consumption growth will continue in 2013 with a 6.2% increase.” PCA continues to explain that “the ...

  • CO2 emission from cement manufacturing and its driving forces in China

    In China, cement manufacturing has contributed 1788.78 million metric tons of CO2 (carbon equivalent) into atmosphere in the past 35 years (1969-2003). Its driving forces were analysed by a stochastic regression model (STIRPAT), which showed that population was a key driving force and its pressure was higher than the global average level. On the other hand, economic growth had less impact, but a ...

  • Waste incineration in cement plants: constraints and development opportunities (a French-German comparison)

    Is it possible to reconcile economic and ecological concerns? This article examines, through a French-German comparison, the case of obtaining a calorific value for wastes used as substitute fuels in cement kilns. On the one hand, this new strategy for obtaining needed inputs offers to the cement industry an economic opportunity for lowering production costs (the main determinant of ...

  • Air Rule for Cement Kilns Requires 92 Percent Cut in Mercury Emissions

    Portland cement kilns will be required to reduce emissions of mercury by 92 percent as part of an Environmental Protection Agency final rule announced Aug. 9 that imposes controls for several toxic pollutants. Although most of the emissions standards in the final rule are less stringent than what the agency had proposed in 2009, the cement industry said the cost to operate the required controls ...

  • Energy Efficiency, Pollution Prevention, and the Bottom Line

    Introduction For many years, efforts to promote energy efficiency and pollution prevention (P2) traveled on parallel paths. Most energy efficiency advocates considered only the energy savings aspects of their projects and most proponents of P2 did not include energy on their list of sources of pollution. More recently, the two groups promoting energy efficiency and P2 have begun to realize the ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Utilization of lime-dried sludge for eco-cement clinker production: effects of different feeding points

    Co-processing lime-dried sludge (LDS) in cement kilns is an appropriate technique to solve the problem of LDS disposal and promote the sustainable development for cement industry. However, there were limited studies that investigated the effects of feeding points on product quality and cement kiln emissions. In this study, simulated experiments were conducted by dividing the feeding points ...
