The dust sources can be broadly divided into process related and
fugitive sources:
I) Process related dust sources
* Drilling;
* Crushing and grinding - Limestone, coal and clinker;
* Kiln and
* Clinker cooler
II)
Fugitive dust sources
* Conveyor transfer points
* Open material stockpiles
* Discharge from hoppers
* Leaking joints
* Raw material transport and handling through dumpers and pay
loaders
Road traffic:
The present traffic density nearest to site on NH 44 is 280 per hour
including all type of vehicles. The contribution due to the proposed
plant will be 80 on daily basis. The transportation vehicles will be
regularized and allowed in such a manner so that there existence does
not disturb the routine traffic. Blow of horns would be prohibited in and
around parking area. The locations of mines are in between hills and
the plant and away from habitat. The mineral transport will not have
any impact on habitat or highway.
2. EMISSION OF GREEN HOUSE GASES (GHGs)
Cement industry's emission of CO 2 is next only to thermal power plants
(coal based). Cement kilns burn coal and limestone both of which
generate CO 2 . The approximate contributions of each of the CO 2
sources are:
Calcinations 50 - 55%
Fuel combustion 40 - 50%
Electricity 0 - 10%
