Partnership scales up carbon dioxide-mineralizing aggregate production

Sources: Kamine Development Corp., Bedminster, N.J.; CP staff

Blue Planet and utility infrastructure specialist Kamine Development have teamed to deploy the former company’s mineralization technology for converting power plant carbon dioxide emissions to a concrete-grade, synthetic limestone. The net CO2-sequestration effect has to potential to offset emissions associated with portland cement production and render a concrete mix designed with the synthetic limestone as carbon neutral or negative.
