Protecting Nature and Biodiversity

TDK uses metals and their oxides as raw materials for the manufacture of various components. These raw materials are made using ore and so on produced from mines around the world. There is a danger that mine development for the extraction of ore exploits limited global resources, destroys scenery, pollutes water, and exerts an adverse impact on the surrounding ecosystem. Concerned about this situation, TDK promotes resource-saving activities that contribute to the protection of biodiversity, including the improvement of production efficiency, prolongation of the life of products through refurbishable design , and strengthened collaboration with recycle businesses.
All TDK employees are aware of the impact on the environment from production activities. We consider the relationship between business operations and the environment and strive to protect a diverse global environment. The TDK Environmental Charter, revised in April 2018, expressly provides that employees are to consider contributions to ecosystems and take proactive action at all times.

About the Guidelines for Action by the Electrical and Electronics Industries concerning Biodiversity Conservation

In March 2015, the "Environmental Strategy Liaison Committee Biodiversity Working Group" formed by four industry associations in Japan* published the "Guidelines for Action by the Electrical and Electronics Industries concerning Biodiversity Conservation (2nd issue published August, 2018)." TDK is fully supporting this initiative and is implementing the guidelines through our activities aimed at protecting biodiversity.

Concrete Activities/Initiatives at Global Sites to Protect Biodiversity

Nature Area in Factory Grounds (Brazil)

At the Gravatai Factory of TDK Electronics do Brasil Ltda. in Brazil, 70% of the factory grounds, which cover an area of about 400,000 sq. meters, are occupied by a nature area.


Situated near the Gravatai River, this nature area has three artificial ponds and is open to local residents as a park. It contributes to the conservation of native flora and fauna. The diverse natural life that can be observed here includes lizards that are about 60 cm long (Tupinambis, a lizard genus belonging to the Telidae family); native bees; crested caracara birds native to South America; parrots; and seasonal flowers. The nature area serves as a pleasant resting place for employees and local residents.

Mangrove Tree-Planting Project (Indonesia)

In 2019 the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) reported that “restoring degraded land is an urgent priority to protect the biodiversity and ecosystem services vital to all life on Earth and to ensure human well-being.”
TDK engages in tree-planting activities around the world. Since three years ago, TDK Electronics Indonesia has been implementing a mangrove tree-planting project at its Batam Factory. In this project, the factory has planted about 1,000 mangroves on the Sembulang Beach together with local residents and children. By taking part, the participants experience and deepen their understanding of the importance of mangrove forests, which are the habitat of a large number of animals. This continuing activity will raise awareness of biodiversity among employees as well.


Project for Releasing Fish into the Chao Phraya River (Thailand)

In March 2021, 30 employees of the Wangnoi and Rojana factories of Magnecomp Precision Technology Public Co., Ltd. and Hutchinson Technology Operations (Thailand) Co., Ltd. released a total of 31,095 carp and other fish, including 95 Mekong giant catfish, into the natural water of the Chao Phraya River in the Bangsai district of Ayutthaya Province.
