2020-1-22  In considering carbon dioxide emissions associated with aggregate production, it should be noted that the crushing of concrete to produce recycled aggregate can be expected to increase its surface area and so increase the potential for carbon dioxide

Decomposition of aggregate CO2 emissions: A production

2008-5-1  Two application studies are presented in this section to illustrate the use of our proposed approach. The first deals with the decomposition of aggregate CO 2 emission changes for eight world regions from 2002 to 2004.

Fugitive dust emissions from aggregate handling Canada.ca

2021-7-31  Aggregate handling includes loading material onto a storage pile and from the pile onto a receiving surface. The calculator focuses on releases to air and uses default emission factors. It can be adapted to use site-specific emission factors. The spreadsheet calculators use emission factors based on uncontrolled emission sources.
