Sal M. El Haggar, in Environmental Solutions, 2005. Cement Industry. The cement industry is one of the main industries necessary for sustainable development. It can be considered the backbone for development. The main pollution source generated from cement industry is the solid waste called cement bypass dust, which is collected from the bottom of the dust filter.
