As per Table 5, dust particles are emitted at the time of clinker crushing, grinding and packing processes, resulting in air pollution. In the clinker operation, emission of particles in different sizes can be prevented through providing an emissions control system under the ‘automation improvement’ option. However, this option is not found to be followed by the sample cement plants. In the grinding operation, the recycling of furnace gas and an adequate ventilation system can be introduced under ‘on-site recycling and reuse’ and
