Murata and the Environment

Environmental Contribution Through Our Products

At Murata, we manufacture environmentally friendly products by thoroughly focusing on the environmental burden throughout their entire life cycle, including parts and materials procurement, design and development, production, use, recycling, and disposal.

A Murata “Eco-friendly Product”

Murata’s thoughts about eco-products

We assess the impact of our products on the environment from the development and design stages, to ensure that every product we offer our customers takes the environment into consideration. Furthermore, by independently evaluating products that contribute more than others to environmental load reduction and certifying them as “eco-products,” we are working to expand our line of these products and to develop technologies that support the ongoing development of eco-friendly products.

Standards for certification of eco-products

Murata’s standards for certification of eco-products require even higher levels of environmental performance than the product assessment standards. Specifically, for certification as an eco-product, a product should satisfy or exceed standards for environmental performance criteria in relation to evaluation items (miniaturization, high performance level, energy conservation, durability) set by Murata, as shown in the table below.

Evaluation item Environmental friendliness of product Environmental friendliness of electronic devices in which product is fitted
  • Reduced use of parts and materials.
  • Reduced energy use in manufacture and transport.
  • Contribution to reduced use of packaging materials.
  • Use of product contributes to miniaturization of electronic devices.
High performance level
  • Improved basic performance.
  • Realization of new functions that make environmental contributions.
  • Use of the product reduces the number of parts in electronic devices.
Energy conservation
  • Reduced energy consumption and circuit loss.
  • Use of the product reduces the energy consumption of electronic devices.
Durability (Longer life)
  • Increased durability.
  • Use of the product increases durability of electronic devices and associated consumables.

Product assessment

Product assessments evaluate the reduction of energy and resources and appropriate management of chemical substances over a product’s life cycle. These assessments enable us to release products to the market that conform to in-house standards based on laws and regulations and on the demands of society.

Introduction of Eco-Products

Example:MEMS Oscillator別ウィンドウで開く

By using MEMS technology, we have achieved the world’s smallest size and low ESR characteristics, which was not possible with quartz crystals. We reduced the number of parts by embedding the required load capacity into the oscillator circuit, contributing to space-saving by customers. We also made use of the low ESR characteristics to reduce the IC gain, making it possible to curtail current consumption by the oscillator circuit, contributing to lower power consumption for the entire device.

Green Procurement

We need to practice “green procurement” to procure more environmentally friendly parts and materials to reduce the environmental burden of our products. To this end, we have been asking our suppliers for their understanding and cooperation to practice their own environmental management.

Promotion of Green Procurement
Evaluating Suppliers’ “Green Level”

Murata has distributed a Green Procurement Standards pamphlet detailing the Group’s philosophy of green procurement and our requirements for suppliers, enabling us to promote green procurement with the understanding and cooperation of our suppliers.

When undertaking business with a new supplier, regardless of where the supplier is located, we investigate the appropriateness of its environmental management system (whether it has acquired ISO 14001 or any other management system certification) and its chemical substance management system, as well as the actual operational condition of those systems. Furthermore, only after the supplier has consented to environmental protection initiatives (such as regulatory compliance and surveys of chemical substances contained in products), do we make a decision on whether or not to undertake business with the supplier.

As for existing suppliers, we conduct evaluations, giving first priority to suppliers who supply parts and materials with high environmental risk. In the case of suppliers whose evaluation results are low, we provide guidance through improvement requests and field audits. If no improvement becomes apparent, we respond rigorously by, for example, suspending business transactions.

Criteria for the Green Level of Suppliers

  • Acquisition of an environmental management system certification
  • Confirmation of the actual operational condition of the chemical substance management system
  • Submission of agreements concerning environmental protection initiatives

Green-Level Investigation of Materials

Before adopting new materials, Murata conducts a green-level investigation for everyone.

As standards for these surveys, we use Murata’s original technical standards, which prohibit or limit the use of certain materials in accordance with legal regulations and customer requirements. Specialized personnel investigate chemical materials that require particular care in handling, and record the materials that pass this inspection in a database to ensure that the Group procures only accepted materials.
