Resource Saving and Waste Reduction
Examples of Initiatives
We are systematically working to reduce the amount of exhaustible raw materials used, quickly and properly dispose of PCB
waste, and reduce the amount of industrial waste sent to landfills. Furthermore, we are setting targets related to recycling industrial and plastic waste and are promoting resource recycling initiatives.
Promoting Resource Saving
We are striving to enhance the economic benefits gained from resource saving activities, such as improving the throughput yieldof exhaustible raw materials and product yield.

Thoroughly Managing Waste and Promoting Increased Recycling Internally and Externally
We have achieved a major reduction in industrial landfill waste by reducing the amount of industrial waste generated and promoting recycling. In addition, as a specified resource industry identified by the Act on Promotion of Effective Use of Resources,
we are also working to reduce the generation of industrial byproducts (sludge). Furthermore, we are setting new targets related
to recycling industrial and plastic waste from fiscal 2021 and are promoting resource recycling initiatives at each worksite andGroup company.
Moving up the Schedule for the Treatment of Waste with Minute Amounts of PCBs before Legal Disposal Deadline Set
by the PCB Special Measures Law
We winnowed the external operators jointly contracted to dispose of waste by Group companies in Japan down to just one.
Regarding the waste with minute amounts of PCBs (transformers, condensers, etc.) being stored or used by each company,
we formulated and are carrying out a plan to treat the waste over multiple years. We plan to treat all applicable equipment byMarch 2025.

Direct Recycling Initiatives for Battery Cathode Materials
We are developing recycling technology that regenerates cathodes collected from used lithium-ion secondary batteries
without returning it to metal. By simplifying the conventional process, CO2 emissions are reduced and recycled cathodematerials can be produced at low energy and cost. JERA Co., Inc. and we were selected for NEDO’s* “Green Innovation
Fund Project: Development of Next-Generation Storage Batteries and Next-Generation Motors”. Both companies will promote development of the recycling technology and social implementation.
