Northern California-based Blue Planet and utility infrastructure specialist Kamine Development, Bedminster, N.J., 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 the potential to offset emissions associated with portland cement production and render a concrete mix designed with the synthetic limestone as carbon neutral or negative.
“This partnership will allow us to scale our profitable technology globally with tremendous efficiency,” says Blue Planet CEO Brent Constantz. “A first run of the market opportunity is that there are over 5,000 identified sites [globally] that would be a good fit for Blue Planet and Kamine Development.” If all the initial sites were developed, he adds, a substantial portion of anthropogenic CO2 emissions could be curtailed the world over.
Constantz holds 100-plus U.S. patents tied to the mineralization process, including those secured during an initial research & development phase under Los Gatos, Calif.-based Calera Corp. Investors and advisors backing his venture include actor Leonardo DiCaprio, a Stanford University past president, and individuals involved with the launch of the LEED green building rating system.
“Blue Planet’s technology has the capability to help reverse climate change on a global level while creating a closed-loop concrete system and simultaneously sequester CO2 from power plants forever,” observes KDC CEO Hal Kamine. “We believe this will become a substantial global business. There is no reason that every building, bridge, road now should not be carbon negative as we can sell these materials into the market at present pricing. This fits into all existing systems in an economical and sustainable way.”
CARBON NEUTRALITY IN 30 YEARS?
Officials of the Global Cement and Concrete Association, London, and Cembureau, the Brussels-based European cement association, anchored a panel discussion during last month’s 25th assembly of the United Nations’ climate action-driven Conference of Parties in Madrid. “Cement and concrete: The path to carbon neutrality by 2050” examined the Cembureau 5C framework: Clinker, Cement, Concrete, Construction and the Built Environment, and (re)Carbonation.
“[We] invite governments to engage with our sector on a full-value chain approach to decarbonization—as outlined in our 5C campaign—on the crucial role of the cement industry in the circular economy, and on innovation projects that are instrumental to lowering our emissions,” said Cembureau Chief Executive Koen Coppenholle.
“Members and affiliates are committed to driving action on sustainability in the cement and concrete industry that supports the global effort to mitigate the extent and impact of climate change,” added GCCA Chief Executive Benjamin Sporton.
