Step 2. Calculate GHG emissions for recycled production of one short ton of the secondary product. The recycled secondary product emission factor is based on life-cycle inventory data for the ambient grinding. TDA pieces are on average 2-12 inches and EPA uses energy data from Corti and 1-7.
Emissions factors were derived from the specific compound recipes shown in Table 4.12-2. Emissions from manufacturing aids such as solvents and adhesives ARE NOT included in these emission factors.

Tub Grinders. Morbark introduced the first industrial tub grinders for use in wood waste recycling and land clearing operations in 1990, and has led the industry ever since. We offer the most complete line of tub grinders available, in a range of sizes and in several configurations – with or without cab and loader, on tracks or tires, diesel ...
The emissions were measured over a 30-minute period and were related to the weight of resin extruded. The emis-sion factor for each substance measured was reported as pounds evolved to the atmosphere per million pounds of polymer processed (ppm[wt/wt]). Processors using similar equipment can use these emission factors as relative refer-
The reaction of rubber with a vulcanizing agent is one factor, amongst many factors that can influence the chemical cross-linking process. Another factor is the presence of functional groups on the surface of the carbon black (Edwards, 1990, West et al., 1978). Since the rCB is produced from EOL tyre pyrolysis, it naturally contains impurities ...
These spreadsheets use emission factors from the latest version of EPA's AP-42 Volume 1 for Stationary Sources. Emission test results may provide more accurate emission estimates and should be considered for use. It may be acceptable to use previous valid source specific test results, or testing that the process equipment's manufacturer ...
For the full 300 miles, in the scenario used for the Draft Truck vs. Train Emissions Analysis, tire and brake wear would contribute roughly 9.5 extra pounds of PM 2.5 in 2023, before implementation of the Advanced Clean Trucks Regulation, and 8 pounds of PM 2.5 after 2035. However, the analysis does not include these emissions because CARB's ...
Emission Factor. An emission factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant. These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity ...

Energy use and CO 2 emissions in the Mexican cement industry are analyzed for the period 1982–94. Using the Laspeyres index method, we estimate the relative importance of fuel intensity, clinker activity, the cement/clinker ratio, and the use of waste tires as an alternative fuel in the changes of clinker fuel use. Changes in CO 2 emissions are divided into energy intensity, cement activity ...
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 ...

For more information on evaluating upstream emissions, see the chapters on Recycling and Source Reduction. WARM includes emission factors for source reduction, recycling, landfilling, and combustion with energy recovery for this material group.
The process of grinding and shredding scrap metal generates heat, resulting in residual fluids and fuels becoming gases. The violent nature of the process creates the potential for particulate matter emissions of various sizes. Thus, the process generates emissions of VOCs, particulate matter, and hazardous air pollutants including lead, zinc,

Concern about auto shredder emissions is not a new issue, but it is a growing one. Shredding automobiles creates very fine particles of dirt and dust that can become airborne. European countries have long-established guidelines. In the U.S., government scrutiny of auto shredder emissions varies from state to state and city to city.

2. An "S" accompanying an emission factor means that this factor is the weighted average sulfur content of the fuel burned, expressed as a percent. See, for example, SCC 1-01-004-01 on page 14.A-3. If the weighed average sulfur content of the Grade 6 oil burned were three percent (3%), then the SOx emission factor would become 157 x 3,
