ABSTRACT: This research study quantifies the PM10 emission rates (g/s)
from cement silos in 25 concrete batching facilities for both controlled and
uncontrolled scenarios by applying the USEPA AP-42 guidelines step-by-step
approach. The study focuses on evaluating the potential environmental impact of
cement dust fugitive emissions from 176 cement silos located in 25 concrete
batching facilities in the M35 Mussafah industrial area of Abu Dhabi, UAE. Emission
factors are crucial for quantifying the PM10 emission rates (g/s)
that support developing source-specific emission estimates for areawide
inventories to identify major sources of pollution that provide screening
sources for compliance monitoring and air dispersion modeling. This requires
data to be collected involves information on production, raw material usage,
energy consumption, and process-related details, this was obtained using
various methods, including field visits, surveys, and interviews with facility
representatives to calculate emission rates accurately. Statistical analysis
was conducted on cement consumption and emission rates for controlled and
uncontrolled sources of the targeted facilities. The data shows that the
average cement consumption among the facilities is approximately 88,160
(MT/yr), with a wide range of variation depending on the facility size and
production rate. The emission rates from controlled sources have an average of
4.752E-04 (g/s), while the rates from uncontrolled sources average
0.6716 (g/s). The analysis shows a significant statistical relationship (p 10 emissions. The study’s findings provide insights
into the impact of cement silo emissions on air quality and the importance of
implementing control measures in concrete batching facilities. The comparative
analysis contributes to understanding emission sources and supports the
development of pollution control strategies in the Ready-Mix industry.
