AP-42: Compilation of Air Emissions Factors | US EPA
AP-42, Compilation of Air Pollutant Emissions Factors, has been published since 1972 as the primary compilation of EPA's 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.

Significant amounts of non-metal materials are contained in the shredded materials, which can vaporize and become organic air emissions. These materials include plastics, paints, caulks, sealants, rubber, switches, fluids, and fluid residues. The process of grinding and shredding scrap metal generates heat, resulting in residual fluids and fuels

After estimating the quantity of each chemical released via wastewater, solid waste, and air emissions, you must deter- mine the amount of each chemical released to water, land, or air or transferred to an offsite disposal facility.
Gouging how-to - Welding Productivity
Air carbon-arc gouging removes metal through the intense heat of an arc created between a carbon electrode and the workpiece. As the material melts, compressed air, which is directed through outlets in the lower jaws of the torch holding the electrode, lifts the molten metal clear of the arc before the metal solidifies.
Air Emission Factors for Metals Finishing Operations
The use of emission factors is the simplest method to estimate emissions from surface finishing process sources. An emission factor relates the quantity of a pollutant released to the atmosphere with a specific activity or in this case a specific process. Emission factors summarized for each process are expressed as a

Clarification and Guidance for the Metal Fabrication Industry
The basic fugitive emission estimation formula is: E - R x EF x (1 - C/100), where E is the emission estimate for the source, R is the facility activity rate or volume. EF is the emission factor, and C is the control devices efficiency.

Since late 2013, ambient air samples of metal particulates have been collected at locations shown on the map below (Figure 1) .
What drives GHG emissions from copper production ...
The grinding media use is typically 1 kg steel/t ore, and assuming 2 t CO2e/t steel consumed, this results in about 0.3 – 0.6 t CO2e/t Cu produced of embedded emissions. This means that copper in concentrate production at an open pit mine site typically results in around 5.5 – 9.5 t CO2e/t Cu if powered by diesel and coal fired power, and ...

Air Emissions The use of metal working fluids in metal shaping and metal removal processes may result in fugitive emissions in the form of smoke, mist, or vapor. Other processes may create more hazardous air emissions. Possible sources of air emissions in metal fabrication processes are: • smoke emissions from metal removal processes
