  • EPA Settles Cement Air Pollution Case

    EPA recently settled a major pollution case with a cement producer on pollution controls that will reduce harmful emissions of nitrogen oxides. Nitrogen oxides are pollutants that can lead to illnesses such as asthma and other respiratory conditions. Nitrogen oxides contribute to the formation of ground-level ozone as well as particle pollution. EPA Regional Administrator, Judith A. Enck ...

  • Cement - The one and only in Estonia

    Estonia is quite a small country and it also lacks good quality rock. However, in the northeast there are quality limestone deposits and also the only cement factory in the country. Today, Kunda Nordic Cement (KNC) follows proudly the tradition of cement production that started there in 1870. Now KNC belongs to the HeidelbergCement Group. Site, acquired recently by Kopar, has been a vital element ...

  • 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 ...

  • Immobilization of organic pollutants in cement pastes admixed with organophilic materials

    The results of 2-chloroaniline (2-CA) immobilization experiments in cement matrices, using an organophilic clay modified with phenolic resins as pre-sorbent, are shown. The 2-CA suspended in water was kept in contact with the organoclay for 24 h, and the slurry obtained was then admixed with ordinary Portland cement (OPC) without additional water, to obtain a firm solid waste. Six cement—clay ...

  • 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 ...

  • 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 ...

  • Possible reuse of Egyptian controlled cement dust

    Possibilities for the reuse of controlled cement dust, collected from the hopper of the electrostatic precipitators installed on the different cement kilns of two of the three biggest companies for Portland cement production located to the south of Cairo, have been investigated. Twenty-one factors representing the physical properties and mineral and chemical composition of the cement dust were ...

  • 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 ...

  • 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 ...

  • Effective Temperature Control for Cement Kiln Off-Gases

    INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of 'dry' operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the ...


  • Increasing the use of recovered mineral components in cement or concrete

    Section 6017(a) of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users, P.L. 109-59, Aug. 10, 2005 (SAFETEA-LU), directs the U.S. Environmental Protection Agency (EPA or the Agency) to, “…conduct a study to determine the extent to which procurement requirements, when fully implemented…may realize energy savings and environmental benefits attainable with ...

  • Total 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, ...

  • Sources of PCDDs/PCDFs In Cement Kiln Emissions

    Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF ...
