Impact of fugitive dust emissions from cement plants

2006-6-15  Dust generated from open sources is termed fugitive because it is not discharged to the atmosphere in a confined flow stream as usually happens with point-sources (Massacci et al., 2003). During the process of cement manufacture considerable amount of dust is emitted at almost every stage.
