of emission inventories can be expected to improve. Much of the process information included in this document is based on the AWMA Air Pollution Engineering Manual and EPAs emission factor document, AP-42 5th edition AWMA, 1992 U.S. EPA, 1995. Other information was
Noise creation reduction is obtained reducing the emission from those sources that contribute to the total emission. This is usually done by decreasing rolling noise sources. Rail dampers and acoustic rail grinding are the two measures of this category that will be discussed in this report. In order to bet-
In recent decades, the cement industry has made great strides towards reducing its carbon emissions. But while the utilisation of alternative fuels is increasing and new technologies are driving efficiency in the cement manufacturing process, a sticking point remains The calcination of limestone is the industrys largest source of emissions.

The purpose of all Emission Estimation Technique EET Manuals in this series is to assist Australian manufacturing, industrial and service facilities to report emissions of listed substances to the National Pollutant Inventory NPI. This Manual describes the procedures and recommended approaches for estimating emissions from facilities
AP-42, Compilation of Air Pollutant Emissions Factors, has been published since 1972 as the primary compilation of EPAs emissions factor information. It contains emissions factors and process information for more than 200 air pollution source categories. A source category is a specific industry sector or group of similar emitting sources.

Grinding is commonly used in applications such as welding preparation and dressing, sand casting post-processing and to remove rust or paint from surfaces. Buffing and polishing are usually multi-stage processes used to smooth rough surfaces andor apply a desired finish to the working metal such as on tools, knives or appliances.
Grinding is a common industrial process in construction-related work. The emissions from grinding metal and other materials can potentially impact the air quality in the region of the work, and thus the health of people who perform the grinding or those nearby. In this study, we measured the size and composition of particles emitted from the
As you identify emission sources, remember to include all sources of air contaminants, such as non-production units like welding or grinding. Also, be sure to include the emission of air contaminants resulting from all aspects of the operation of a process. Ancillary activities such
