Basic Approach

In our Environmental Policy, we express our commitment to complying with all relevant environmental laws, regulations, and guidelines, as well as with each customer's specific guidelines. We have set the following as part of our Action Guidelines.
"In respect of chemical substances which are harmful to both the environment and human body, Yokowo will prevent environmental pollution by implementing preventive measures and action plan, which include those for the case of abnormal and emergency operation, and will minimize the use of hazardous chemical substances."
"Yokowo will comply with all relevant environmental laws, regulations, and each customer's specific requirements, and intend to enhance our environmental management by our original internal standards."

Management system

Yokowo is promoting Chemical substance under the following system.

As for chemical substances, we operate in accordance with the standards set in Japan, including those in other countries.
We conduct management activities targeting chemical substances
used in our processes that may be harmful to the natural environment or human health.
Meanwhile, the management of chemical substances contained in products is handled by the technical department.

Target

For chemical substances that may be harmful to the environment or human health, we establish preventive measures and response procedures, including those for abnormal and emergency situations, to prevent environmental contamination. In addition, we promote the proper management and reduction of hazardous substances to ensure that our activities do not hinder the transition to a circular economy.

Major Initiatives

At the Yokowo Group, we have established the Standards for Managing Chemical Substances Contained in Products (hereafter, the “Standards”). These Standards clearly define the substances subject to management that are contained in parts, materials, and other components used in products manufactured and sold by the Group. We also ensure thorough communication of these Standards within the Group and to our business partners, as part of our efforts to enhance environmental quality.
The Standards set forth methods for managing chemical substances throughout the entire process—from the acceptance of raw materials and parts to shipment.
For components used in our products, we place particular emphasis on information sharing with suppliers. We conduct rigorous inspections using inductively coupled plasma (ICP) analyzers and fluorescent X-ray analyzers, while supplying products that comply with evolving chemical substance regulations set by global automotive and electronics manufacturers.

Management of Chemicals Contained in Products

Response to the REACH Regulation

To observe the duty to communicate information on substances of very high concern (SVHC) and the regulations on restricted substances, we obtain information about the presence of chemical substances via our business partners and manage that information.

Response to the RoHS Directive

We confirm that all delivered parts and materials conform to the RoHS Directive. We have also built an internal inspection framework.

Regulatory Compliance and Chemical Substance Management Framework

At the Tomioka Plant, we have introduced an SDS management system to improve the efficiency of chemical substance risk assessments. In addition, departments in Japan that handle certain poisonous and deleterious substances have implemented a chemical management system to ensure proper handling of chemicals. Going forward, we will continue to strengthen our management framework in line with legal and other requirements, while working to enhance safety and reduce environmental impact.
