AIR POLLUTION CONTROL IN THE CEMENT INDUSTRY. by Russell E. Hailstone Technical Director General Portland Cement Company Dallas, Texas. Portland cement manufacturing plants both old and new located in congested and sparsely populated areas of the country have, for many years, installed the most modern and efficient emission control
Ways to Reduce Air Pollution from Factories. We can reduce air pollution by conserving energy by turning off lights, computers, air conditioners and other appliances when not in use. Encourage your employees to use public transport or you can arrange a bus from a common point for your employees.
The Table shows that if all US plants would upgrade their pyroprocessing to the level of the best US plant ( a dry process system with preheater with precalciner technology), the industry would lower its energy consumption by 30% to approximately 3,407,650 Jouls/tonne of cement and reduce CO 2 emissions by 13% to Mt/year.
Industrial activities play a key role in the economic wellbeing of a country but they usually involve processes with a more or less profound environmental impact, including emission of pollutants. Among them, much attention has been given to airborne particulate matter (PM) whose exposure is ubiquitous and linked with several adverse health effects mainly due to its size and chemical composition.
Similarly to our findings, Merenu et al. 2007 [6] investigated the effect of cement dust exposure on 56 cement factory workers with a mean of 10 years exposure to cement dust on lung function. They found that the vital capacity and forced expiratory volume in one second were significantly lower in cement factory workers than in control subjects.
The majority of all cement shipments, approximately 70 percent, are sent to readymix concrete operators. The rest are shipped to manufacturers of concrete related products, contractors, materials dealers, oil well/mining/drilling companies, as well as government entities. The domestic cement industry is regional in nature.

emissions [2]. Concern over the impact of anthropogenic carbon emissions on the global climate has increased in recent years due to growth in global warming awareness. In addition to the generation of CO2 the cement manufacturing process produces millions of tons of the waste product cement kiln dust .
Cement and concrete manufacture Where are the hazards? High levels of dust can be produced when cement is handled, for example when emptying or disposing of bags. Scabbling or concrete cutting can also produce high levels of dust that may contain silica. What are the risks?
Environmental impacts. Cement manufacture causes environmental impacts at all stages of the process. These include emissions of airborne pollution in the form of dust, gases, noise and vibration when operating machinery and during blasting in quarries, and damage to countryside from quarrying.
