Mitsubishi Corporation (MC) is pleased to announce that its proposal for researching and developing
new ways to use CO2 in the production of concrete has been selected for the NEDO1 grant project that
encompasses technological developments in the areas of carbon-recycling.

Carbon-recycling technologies make effective use of CO2 emissions captured from steel mills, power
plants, cement manufacturing plants and other facilities to create value-added products. They are
being developed as a means to help address climate change. Having recognized their potential, MC is
working on those that inject CO2 into concrete, where it becomes mineralized and permanently
embedded. Concrete is an essential material for civil engineering and construction projects, and its
global market is growing.

Most of the current carbon-recycling technologies are mainly used for a limited scope of unreinforced
concrete, such as concrete blocks, so the challenge now is to enhance their mineralization capabilities
and broaden their applications.

This joint endeavor between MC, Kajima Corporation and Chugoku Electric Power Co.,Inc. aims to
improve these technologies so that they can also be applied to the reinforced and cast-in-place
concretes used in building construction.

MC has already been involved in the development of concrete projects that take advantage of carbon recycling, including a zero-emission, ecological concrete called CO2-SUICOM2.

CCUS3 technology including Carbon-recycling is an excellent opportunity for MC to leverage its
strengths, as collaborations are essential across industries that both emit and use CO2. By developing
such businesses, MC will realize its vision of simultaneously generating economic, societal and
environmental value.
