PRESS RELEASE

Feb 05, 2021
Chiyoda Corporation agree an MOU with Mitsubishi Corporation and Blue Planet Systems
Corporation
Chiyoda Corporation (Chiyoda) is pleased to announce that it has entered into a Memorandum ofUnderstanding (MOU) with Mitsubishi Corporation (MC) and Blue Planet Systems Corporation (BluePlanet) to accelerate the development and commercialization of Blue Planet’s technology to produce CO2sequestered aggregates.
Blue Planet has been developing the technology to commercially manufacture aggregate, a raw material
for concrete, by immobilizing CO2 contained in exhaust gas as calcium carbonate, since its founding in2012. MC is providing financing to Blue Planet (press release dated 23 September 2020) and has enteredinto partnership with Blue Planet to commercialize the technology.
The development of carbon recycle technologies to recover CO2 as a resource is central to reducing CO2emissions, an important measure against climate change. By applying its knowledge of engineering andchemical engineering in particular, Chiyoda will participate in a planned project to demonstrate thetechnology in Silicone Valley, California, towards the establishment of the technology andcommercialization.
Chiyoda is also progressing initiatives in the synthesis gas field (*1) and in the electrolytic reduction field(*2), toward the realization of a carbon recycling society.
An overview of Blue Planet’s technology is shown below:

1Comment by Dr. Brent Constantz, Founder and Chief Executive Officer of Blue Planet:“Blue Planet and Chiyoda intend to collaborate together on the commercialization of Blue Planet’s carbon
mineralization technology. Chiyoda is Mitsubishi Corporation’s engineering partner and Chiyoda’s diverseengineering experience will enable Mitsubishi to rapidly commercialize Blue Planet plants, by capturing
and permanently sequestering Gigatons of CO2 annually in the form of synthetic limestone aggregates forconcrete”.
