A successful assessment of the state of the art of collection, disposal and utilization of waste kiln dust required a review of pertinent technical literature. Chemical Abstracts, the reference files of the Portland Cement Association and a bibliography from the Tennessee Valley Authority were used to gain initial access to the literature.
machines used in cement factories and coal burning power plants that remove dust particles from smoke stacks Smog urban air pollution composed of a mixture of smoke and fog produced from industrial pollutants and burning fuels.
the finished cement. The cement production technologies in use cause extensive power consumption, gas emissions, noise pollution environmental heating and emissions of fuel (CO2, NOX SO2 and CO) from the kiln and precalciner. These are the major sources of environmental pollution in the cement industry to the best possible extent.
The purpose of this paper is to identify the most critical factors of cement industry that have a negative impact on the environment, human health and plant species in the context of Pakistan.,The factors are categorized into air pollution, noise pollution, soil pollution, human health and plant species.
Each step of cement manufacturing, physical conditions and reactions occurred are explained here. Raw material transportation. Limestone is carried to the plant from mining place usually by a train. Some cement plants import clinker from other country or plant and add gypsum to produce cement. Mixing and Drying of limestone and clay
A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement.

The plant makes use of supplemental cementicious materials (SCMs) as much as possible in place of ordinary portland cement, thereby both reducing the greenhouse gas emissions and carbon footprint associated with cement, and also helping reduce the amount of waste the plant's area has to deal with.
The aim of this study was to investigate the health risks due to combustor emissions in the manufacturing of Portland cement for the population living in the neighborhood of a cement kiln in Catalonia, Spain. Pollutants emitted to the atmosphere in the course of cement production were modeled.
The problem of noise pollution is evaluated in Assuit Cement Company (CEMEX). The study is conducted in the limestone quarry and cement plant. Noise levels is predicted using the prediction model. Also, noise levels were calculated based on the machine data. Measurements were carried out using Bruel & Kjaer, sound level meter Type 2230 at
cement industry is an energy enormous intensive and products many emissions, odors and noise. The emissions from cement plants which cause greatest concern and which need to be dealt with are dust, carbon dioxide CO2, nitrogen oxides (NOx) and sulphur dioxide (SO2).
