Approach to Environmental Conservation

We manufacture and sell products and provide solution services based on these products, focusing on analog semiconductors. With the coming of the Internet of Things (IoT),* in which a wide array of objects are computerized and connected via networks, analog semiconductors will be embedded in the devices used in our daily lives and industrial activities, acting as key components to provide people with new experiences and create new value.
If the energy-saving performance of analog semiconductors was improved, for example, this would reduce the power consumption of the electronic components embedded in various devices, contributing to a reduction on the environmental impact of society as a whole.

To accomplish this, we are thoroughly knowledgeable of the characteristics of our business, and engage in ongoing environmental conservation activities aimed not only at reducing the environmental impact of our business processes, but also at helping reduce the environmental impact of society itself through our products and solutions.

* Internet of Things. “The IoT concept refers to a state where vehicles, white appliances, robots, facilities, and nearly all other things connect to the Internet and exchange information with each other. According to the concept, as things are converted into data and automation based on these data progresses, new added value will be generated.” (Source: Ministry of Internal Affairs and Communications “White Paper 2015: Information and Communications in Japan” Part 2, Chapter 5 Section 4 “Structural Changes in the Economy Caused by ICT Advancement”).

Environmental Policy

We aim to achieve harmony between corporate activities and the environment by engaging in environmental activities under our “Three Greens” concept (Green Processes, Green Products, and Green Life). We contribute to the creation of a sustainable society in which all life can coexist.

Environmental Management System

Until December 2017, we consigned our environmental management to Seiko Instruments Inc., collaborating with the company’s environmental management promotion system and implementing environmental conservation activities. Specifically, we created an environmental management system in accordance with the ISO 14001 international standard, thoroughly implementing the PDCA management cycle to improve environmental performance.

Our environmental activity promotion system

In January 2016, we split off Seiko Instruments Inc.’s semiconductor business, establishing a new company through joint funding with the Development Bank of Japan Inc. (DBJ). Our production sites, the Takatsuka Unit in Chiba Prefecture and the Akita Unit in Akita Prefecture, were used jointly by Seiko Instruments Inc. and its affiliates, so we plan to establish an organization in charge of environmental conservation activities within our own General Administration Department by March 2019. This department will promote environmental conservation measures in cooperation with the Environmental Management Promotion Department of Seiko Instruments Inc.

Environmental Activities and Results

We are conducting the following activities based on our environmental policy.

1. Energy-saving Measures

– Energy-saving product development

We leverage the features of CMOS ICs to develop energy-saving products with low power consumption levels.

– Manufacturing process energy consumption reductions

Our semiconductor product-manufacturing plants are taking the lead in reducing the power used in manufacturing processes.

2. Zero emission (zero landfill waste) measures

We actively recycle the etching fluid, washing fluid, packaging material, and other materials used in our semiconductor product manufacturing processes, working to reduce the amount of waste we produce. Our staff departments also not only sort and separate garbage, but also actively promote the recycling of paper used in day-to-day business operations.

3. Chemical substance management

– Chemical substance impact mitigation

In order to safely manage chemical substances and prevent them from having negative impacts on peoples’ health or the environment, of the chemical substances we use in our production processes, we thoroughly manage emissions and transport volumes not only of chemical substances designated under the PRTR Act*, but also of managed substances voluntarily designated by our ourselves (22 substances) and volatile organic compounds (VOCs) (100 substances).
We also appropriately manage and reduce emissions of other chemical substances, quickly eliminating the use of all ozone-destroying substances (specified CFCs in August 1992 and trichloroethane in November 1993), voluntarily eliminating the use of all chlorine-based organic solvents (in March 1999), and eliminating the use of all HCFC-141b chlorofluorocarbon alternative (a greenhouse gas) (in March 2000).

– Lead-free solder measures

In response to globally expanding regulations regarding the chemical substances used in products, in December 2003 we eliminated the use of lead in the solder plating of the leads in our semiconductor products.

– Compliance with REACH regulations

In order to comply with European REACH regulations, we obtain and manage information regarding the chemical substances contained in products via our supply chain, and appropriately convey this information to sellers of our products, etc., when necessary.

4. Environmentally conscious product design measures

We perform environmental assessments when developing new products, investigating the usage of prohibited substances and regulated substances. We make decisions regarding the use of materials in our products after acquiring and evaluating environmental impact and safety-related information from MSDS (material safety data sheets), working to reduce environmental impacts from the product design stage.

5. Green procurement measures

Based on our internal Green Procurement Standards, we collaborate with suppliers to prioritize the purchasing of environmentally-friendly articles.

6. Global warming countermeasures

In FY2016 (April 2016 to March 2017) we emitted 23,085t of CO2 and had a CO2 emission intensity of 31 tons of CO2 per million yen.

7. Efficient resource utilization

In FY2016 our total waste production was 806 tons, our landfill waste production was 1 ton, and we had a recycling rate of 74%. We used 203,912 m3 of water. We have designated individual targets for FY2017 onwards and are working to reduce the amount of resources that we use.

Total waste production and recycling rate (FY2016)

General waste 68,319 kg
Sludge 210,529 kg
Oil waste 3,025 kg
Acid waste 45,368 kg
Alkali waste 33,091 kg
