Environment Policy

This “Environmental Policy of the Mitsubishi Materials Group” was established based on the Sustainability Policy and is considered to be the foundation for the business activities of the Mitsubishi Materials Group.

Promote Recycling and Provide Environmentally Friendly Products
We leverage our advanced recycling technologies to promote recycling of waste. At the same time, we provide environmentally friendly materials and products across our business activities starting from raw material procurement to the development, production, distribution, consumption, disposal and recycling of raw materials and products.
Advance Decarbonization
We work towards the decarbonization of our business activities by reducing energy consumption. We will also tap into geothermal and other renewable energy sources to decarbonize our entire value chain.
Respect Biodiversity
We engage in business activities that take ecosystems into account throughout our value chain, including the development of natural resources.
Effectively Use and Conserve Water Resources
We work to reduce water consumption through circular water management and reuse of cooling water, cleaning water and all other water used across our business activities.
Sustainably Manage Company-Owned Forests
We make effective use of timber and other forest resources as well as ensure appropriate management of company-owned forests that contribute to decarbonization, biodiversity and water conservation and recreational activities of the local communities.
Encourage Environmental Education and Harmonious Coexistence with Society
We strive to reduce the environmental impact from our business activities and prevent pollution by educating all our employees on relevant laws, regulations, and agreements on an on-going basis. We communicate proactively with our stakeholders and engage in environmental conservation initiatives.

(Last revised date : December 1, 2021)

Framework

We have established the Environmental Management Panel to be a dedicated subcommittee under the Sustainable Management Office that formulates and implements group-wide environmental measures. We appoint environmental management supervisors for each business division and manufacturing site. They work to prevent pollution and ensure compliance with environmental laws and regulations by collaborating closely with the Head Office environmental management department.

Environmental Management Activities

Environmental Training

We operate environmental management systems under the ISO 14001 standard and other environmental management systems at our facilities. Under those systems, we engage in continuous activities to ensure compliance with laws and regulations and improve our environmental performance. We implemented environmental training programs to promote the acquisition of knowledge regarding environmental technologies, laws and regulations which are needed by managers who promote the above activities. We are also developing and implementing a checking system for applicable laws and regulations required for day-to-day management.

Environmental Management Training
Management-level staff at our various facilities receive education designed to improve their understanding of pollution prevention management systems, and other basic management requirements from an environmental management perspective.
Waste Management Training
While the Group emits various types of waste as a consequence of its business activities, we also promote the use of recycled raw materials, such as in our metal smelting and refining business. We therefore regard waste management as a key business process, and we appoint staff who are responsible for waste management, and those in charge of practical operations at each facility.We provide training on laws and regulations and apply strict operating rules in our efforts to ensure appropriate waste management and compliance with relevant laws and regulations.We carry out waste management training for  staff who is responsible for waste management and for those in charge of practical operations.
For staff responsible for waste management, we provide education with the aim of understanding waste risks and the roles required by introducing the latest case studies on waste management.
For staff in charge of practical operations, we organize seminars for understanding the specific regulations of the Waste Management and Public Cleansing Act that are imposed on waste generators.

Sharing Information to Address Environmental Issues

To handle the environmental issues that arise at our facilities, we have established an office providing the consultation services of staff specialized in environmental issues, at our Head Office. This office provides meticulous support, ensures that information useful in tackling environmental issues is shared between the Head Office and other facilities.
We hold an annual Meeting of Administrative Managers Responsible for Environmental Management for management-level staff at our facilities. At these meetings, we share information about environmental measures and issues. In addition, we give annual facility tours for environmental management supervisors at individual facilities. These tours are hands-on opportunities to learn methods of operating onsite related to environmental management and initiatives for preventing environmental accidents, and to exchange information with supervisors from other facilities.

Compliance with Environmental Laws and Regulations

We keep all our facilities up to date on changes in legislation applied to the Mitsubishi Materials Group by providing information via intranet or email. In the event of major revisions or revisions requiring measures such as equipment upgrades, we hold explanatory meetings to share information on the requisite measures and ensure that all our facilities are prepared to take appropriate action.
Currently applicable laws and regulations are checked periodically at each facility. In addition, the Internal Audit Department checks the status of compliance with environmental laws and regulations, how chemical substances are handled, how equipment is managed and so on. Any noncompliance discovered shall be corrected promptly and its information shall be shared with related facilities as part of our efforts to improve the level of management in the overall Group.
In the event of installation of new facilities, facilities upgrades/changes, or any other projects involving new operations above a certain scale, individual sites determine what notifications they are required to submit by law, and confirmation is also made by the relevant Head Office divisions. In addition, as a support function in the aspect of specialized legal knowledge that is needed at sites, we built a web system and began operating it in April 2021. When a name or the specifications of a facility are entered in this system, it automatically judges whether a notification or a permit application needs to be submitted about the facility in accordance with the law.

Status of Compliance with Environmental Laws and Regulations

With regard to our compliance with environment-related laws and regulations in fiscal 2022, we were not subject to any adverse dispositions (revoked permits, orders to cease operations, orders to stop use of equipment, fines, etc.) by regulatory authorities.
We received 7 complaints regarding noise and dust. For all of these we promptly investigated the causes and implemented the necessary countermeasures.

Addressing Environmental Risks

In accordance with our Environmental Policy, we identify environmental risks to the Mitsubishi Materials Group from a broad perspective and take measures to prevent such risks from materializing.
Pollution of air, bodies of water, soil or groundwater by hazardous  substances leak, or inadequate treatment of industrial waste  could have a detrimental impact on the environment, as well as a serious impact on our business activities as a group. We carry out risk assessments in line with the nature of our business activities, the substances that we handle, and the locations of individual facilities, and take action as necessary. In addition to preventing inadequate waste treatment at our own facilities, we take steps to ensure that we do not overlook inadequate treatment by contractors by taking measures including on-site confirmation.
At the abandoned mines (non-ferrous metal mines) we own, in order to prevent mining-induced pollution, we continue to maintain tailings dams, mining tunnels and mining water conduit, and to appropriately process acid wastewater containing heavy metals generated from these locations.
Biodiversity is also an important environmental risk for us. At the mines from which we procure raw materials (such as ores), we have established environmental and social standards, including standards for the conservation of biodiversity, and we confirm our compliance with these standards. In addition, we manage the company-owned forests in Japan to ensure a high level of ecosystem services from them. They fulfill a certain standard that has been assured by our acquisition of a forest certification.
To reduce climate change risks, we take multiple approaches for the conservation of energy and the reduction of CO2 emissions. We also study CO2 capture and use, and generate renewable energy. Regarding the risk that a shortage of freshwater resources could impact our business activities, we conduct risk assessments for our major facilities in Japan and overseas and take measures including the effective utilization of seawater, water conservation through the improvement of the efficiency of the production process, water recycling, and ensuring that wastewater is treated and purified.

Overall Environmental Impact

INPUT・OUTPUT

  • In the process of the integration of Cement business and related businesses between UBE Corporation (formerly Ube Industries, Ltd.), on April 1, 2022, MMC's Cement business and related businesses were assumed by Mitsubishi UBE Cement Corporation (an equity method affiliate of MMC) through an absorption-type company split.
    Regarding the aluminum business, on March 31, 2022, we transferred all of our shares of Universal Can Corporation to Showa Aluminum Can Corporation, and on the same day, we split the Aluminum rolling and processing business from Mitsubishi Aluminum Co., Ltd. into Showa Aluminum Can Corporation through an absorption-type company split.

Among the following disclosure items, energy input includes data from sites belonging to the cement business and the aluminum business. The other disclosure items include data from facilities belonging to the cement business while they do not include data from sites belonging to the aluminum business.

Total Energy Input

Total energy input (non-consolidated) in fiscal 2022 decreased by 0.15% (0.1 petajoules: crude oil equivalent of 2 thousand kiloliters) in comparison with fiscal 2021.
While there was an increase in activity levels at other plants and locations despite falling production volume at some cement plants, this was offset by an increase in the use of waste plastic and other alternative thermal energy resources, producing results that were largely on par with FY2021.
