Contributing to Realizing the SDGs
The Maxell Group has formulated its Corporate Sustainability
Vision for contributing to the Earth 100 years from
now through
its mission: "Contribute to a sustainable
society by innovating
unique, original technologies."
The 193 UN member countries, including Japan, unanimously adopted the SDGs (Sustainable Development Goals) at the UN Sustainable Development Summit in September 2015.
The SDGs comprise 17 goals and 169 targets, which stem
from social issues that governments around the world aim to resolve on a global basis by 2030.
In addition, identifying companies in all industries as important partners, this initiative calls for the active participation
of companies in addressing and achieving the SDGs.
Accordingly, through its products and services and CSR activities, the Maxell Group will contribute to the realization of the SDGs.
The Maxell Group’s CSV
Business Management
The Maxell Group has placed greater emphasis on sustainability activities and established a dedicated department in FY2020 to strengthen the linkage between environmental and social issues and business.
As the world has been changing rapidly, we recognize the need to respond flexibly to these changes. Starting in FY2022, we will establish a system to further strengthen our corporate communication and promote information disclosure regarding our various responses to social changes and their development in the Maxell Group's business activities.

Galvanic cell-type Lead-Free
Oxygen Sensors (O2 Sensors)
- Value Proposition
-
Although lead, a substance subject to the European RoHS Directive, is a hazardous chemical, it is exempted from use in oxygen sensors, for which no alternative technology has been established, and is used throughout the world. At Maxell, we are committed to solving social environmental issues by focusing its management resources on lead-free oxygen sensors, which are environmentally friendly products that we sell. By developing an anode that replaces lead and a weakly acidic electrolyte that is suitable for the anode, we have commercialized a long-life galvanic cell-type lead-free* oxygen sensor that is less susceptible to CO2 and other acidic gases. By not using lead* as an anode, we are reducing the risk of soil and marine pollution and its impact on the human body. *It means that the lead contained in each part (homogeneous substance) constituting the product is 0.1wt% or less.

Waterproof and airtight tape
(Butyl tape)
- Value Proposition
-
By reducing water leakage, mold growth, rusting of metal parts, and deterioration of wall and ceiling materials in buildings, waste is reduced. It also helps to improve the efficiency of air conditioning by filling in the gaps between housing components, such as around pipes leading to the interior and exterior of the building. In Southeast Asia, we are promoting the construction of houses using the tarpaulin method, and in North America, we are promoting the use of airtight materials.
Waterproof and airtight tape (Butyl tape)
By spreading the use of the tarpaulin method and airtight materials, we will not only improve the living space in the region, but also improve the skills of local contractors and consider the environment.
Approach to make social contributions
Maxell Group believes that its responsibility as a good corporate citizen is to develop community-based activities as a member of local communities, in addition to solving social issues through its business. We actively promote a variety of social contribution activities in order to realize a better society.
With Local Communities and Society.
Maxell Group is deeply aware that it is a member of society, and its basic philosophy is to devote itself to fair and transparent corporate behavior. At the same time, we strive to realize a truly affluent society as a good citizen through harmony with the environment and proactive social contribution activities. In order for Maxell Group, which has bases around the world, to coexist and co-prosper with society, employees take the initiative in conducting social contribution activities under the three pillars of “next-generation education,” “environmental conservation,” and “coexistence with the community.”
Next-generation education.
We want local elementary and junior high school students to experience the 'joy of working,' 'joy of making,' and 'joy of learning' through hands-on learning and manufacturing education at companies, not typically offered in schools.
With this in mind, Maxell Frontier Inc.’s Miyagi Works, Yonezawa Works, as well as Maxell, Ltd.’s Ono Works, have welcomed junior high school students and provided them with work experience opportunities. Additionally, Maxell’s Kyoto Works held a battery workshop for elementary school students.
Next-generation education.
Maxell participates in "Da Vinci Masters," a program that provides children with opportunities to develop "self-confidence, thinking, action, collaboration with others, and social skills" while having fun and enhancing their "non-cognitive abilities" through an original hands-on program.
Held at Maxell Aqua Park Shinagawa in March 2022.
The program conveyed awareness of disasters caused by climate change and the importance of disaster prevention and preparedness, and introduced an experiment and its mechanism to generate electricity with salt water and air using "Mizushion," a lantern that is useful in times of disaster.
Held at Maxell Aqua Park Shinagawa in February and October 2023.
The program introduced our analog core technology, which is the pride of our company, and showed the depth of the "mixing" technology that leads to the development and manufacture of batteries, and provided a hands-on experience of science through experiments with *Bettalin, which is made by "mixing".

Environmental preservation.
As part of our efforts to contribute to the local community and improve the environment, each of our business sites takes initiative in cleaning up the area around the site. (The pictures are an example.) In addition, the Kyoto HQ has invited volunteers to help clean up nearby beaches by picking up marine debris, mainly marine plastics.
Coexistence with communities.
As a member of the local community, we actively participate in community-based activities both in Japan and overseas. For example, Maxell's Kawasaki and Kobuchisawa Works contributed to polio vaccines through the collection of used postcards and other materials. In a collaborative effort, employees and their families gathered 222kg of aluminum cans, the proceeds from which were used to purchase a wheelchair that was donated to a social welfare organization. Twice a year, Maxell's Kyoto Works conducts a 'flower-filled activity' with two local elementary schools in the city of Oyamazaki. Students serving on the environment and horticulture committees are taught how to plant the flowers and sometimes discuss environmental issues while participating in friendly activities. Additionally, these flowers are displayed at athletic events, commencement, and graduation ceremonies.
"Green Stencil Program" to support tree planting activities
The Maxell Group's activities to combat global warming include ongoing efforts to conserve energy at plants and introduce renewable energy. Trees absorb carbon dioxide from the atmosphere and store carbon in their bodies, making tree planting an effective means of reducing CO2 emissions. Maxell donates a portion of the proceeds from sales of electroformed products developed and manufactured using its precision microfabrication technology to plant larch trees. The larch will contribute to a reduction of approximately 250 kilograms of CO2 over 30 years. We have named this program "Green Stencil Program" and continue to promote it.
