Basic Policy on R&D

Developing New Products and Technologies to Anticipate Changes in the World around Us

Our basic policy when it comes to development is to precisely identify customers’ needs and future technology trends, and to develop and provide products and technologies that anticipate changes in the world around us. With this policy in mind, we aim to provide the Earth with new materials that make the most of the group’s unique technologies. This means creating distinctive products and technologies that will be competitive in the global market, and upholding our strategy of becoming a world’s leading company.
We also engage in a development strategy with the aim of creating timely new products and technologies that will help us to become the number one, and “only one”, in each of our lines of business in the short term. Over the medium term, we intend to focus on developing new core businesses that will underpin the sustainable growth of the entire group, particularly in next-generation vehicles, IoT and AI-related products and areas where we can contribute to a realization of fulfilling sustainable society. On a longer-term basis, we intend to boldly take on the challenge of creating inspirational new technologies for the future. Combining technology, human resources and passion, our aim is to continually achieve innovation, with an emphasis on the customer’s perspective and speed.

Examples of Environmentally Friendly Development

We are also committed to improving manufacturing processes, and reducing environmental impact from our materials and components. We use computer analysis technologies to optimize operating conditions to reduce CO2 emissions derived from thermal energy from our plants. We have rolled out the technology to manufacturing processes for copper smelting and polycrystalline silicon, to enable us to improve quality and increase efficiency. We are also working on technologies capable of harnessing alternatives to fossil fuels, including waste plastic and shredder dust, as well as using recycled raw materials in the smelting process and recovering rare metals from urban mines. In an effort to save energy and extend the life span of our materials and components meanwhile, we are working on development in areas such as coating films for cemented carbide products, battery materials, connector terminals, insulated circuit substrates and temperature sensors.

Major Achievements in FY2022

Field Item Details
Renewable energy Participation in NEDO's Green Innovation Fund Project/Development of Next-Generation Solar Cells We are participating in a Green Innovation Fund Project as a company commissioned by EneCoat Technologies Co., Ltd., which we finance. We develop peripheral materials to reduce costs and improve the performance of perovskite solar cells to facilitate the wide use of the cells.
Recycling Joint research with Emulsion Flow Technologies started We have started joint research with Emulsion Flow Technologies Ltd. on metal recycling technology using the emulsion-flow method, which is an advanced solvent extraction method.
Carbon Recycling Technology Adopted as an R&D Project Commissioned by NEDO

For the creation of a new business for carbon neutrality, we set about research and development in 2017 for a technology to decompose carbon dioxide (CO2) for recycling as a carbon material. In October 2021, we have been adopted as a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO) with the title of "Development of Carbon Material Manufacturing Technology by Chemical Decomposition of Carbon Dioxide" in the field of "Development of Technologies for Carbon Recycling and Next-Generation Thermal Power Generation / Development of Technologies for CO2 Reduction and Utilization".
This technology uses the reaction of an activated reducing agent (powdered metal oxide) with CO2 to break down and recover the CO2 as a particulate carbon nanomaterial (a valuable resource). The recovered carbon nanomaterial is expected to be used in a variety of applications as a source of carbon.
Many carbon recycling technologies require hydrogen. Features of this technology are that the amount of hydrogen the process requires is relatively small, hydrogen is even generated by the process, and it is a cyclical process in which the reducing agent and other materials can be reused.
We will continue to contribute to the building of a decarbonized society by working on the reduction of CO2 emissions and effective utilization of carbon including practical application of this technology.
