TRPs are generally a mixture of tailpipe emissions of combustion PM, tire- and break-wear PM, and mineral PM from road pavement abrasion.
Cd pollution in soil, air, and water is ubiquitous because of Cd use in industrial products (e.g., batteries, coatings, plastic stabilizers), contamination of phosphate fertilizers, and release from motor vehicle fuel combustion and tire wear (Agency for Toxic Substances and Disease Registry 2011).
Notwithstanding this requirement, if a unit combusts both MSW and tires and the reporter elects not to separately calculate and report biogenic CO2 emissions from the combustion of tires, Tier 1 may be used for the MSW combustion, provided that no more than 10percentt of the unit's annual heat input is derived from MSW. (A) The use of Tier 4 is not required.
Separate reporting of biogenic CO2 emissions from the combustion of tires is also optional, but may be reported by following the provisions of paragraph (e)(3) of this section.
This equation may not be used to calculate biogenic CO2 emissions from the combustion of tires or MSW; the methods described in paragraph (e)(3) of this section must be used for those fuels.
These procedures also may be used for any unit that co-fires biomass and fossil fuels, including units equipped with a CO2 CEMS, and units for which optional separate reporting of biogenic CO2 emissions from the combustion of tires is selected.
Finally, the conclusions achieved from this study can be used not only for pyrolysis process design but also for the interpretation and modeling of the tire rubber combustion process.
You don't need to know the principles of combustion to change a tire, as an old sage once told me.
(vii) May be used for the combustion of MSW and/or tires in a unit, provided that no more than 10percentt of the unit's annual heat input is derived from those fuels, combined.
