Source Reduction:: S03: Substituted raw materials, feedstock, or reactant chemical
|
Methods to Identify SR Opportunities: T10: Vendor assistance
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies. |
S03: Lead is contained in the cement and fly ash used for manufacturing concrete. Slag is used as a substitute for cement. Source Reduction - Cement usage is reduced by injecting CO2 into concrete during mixing using CarbonCure technology. The process reduces the amount of cement required for producing concrete by about 4-6%. Hence the lead emissions are reduced. Barriers to P2: B7 - No known substitutes or alternative technologies. - Known substitutes have been implemented |

Barriers to P2: B7 - No known substitutes or alternative technologies. - Lead is found in raw materials (cement and fly ash) that are used in ready-mix concrete manufacturing. Other Environmental Practices: General Environmental Management - Daily observation of any visible emission and regular maintenance of dust-controlled devices. |

Source Reduction: Source Reduction - Lead is found in the portland cement. The carbon dioxide (CO2) is injected into concrete during mixing, where it undergoes a chemical reaction and converts into a mineral. This CO mineralization process reduces the amount of cementitious content in concrete mix designs and carbon footprint reductions. Therefore the amount of toxic chemicals entering an environment has been reduced. |
