Quality & Environmental Activities

Participating in the climate change campaign
“Fun to Share”

The climate change campaign “Fun to Share”, organized by Japan's Ministry of the Environment, commenced in March 2014.
“Fun to Share” is a slogan advocating the sharing of techniques and initiatives to achieve a low-carbon society while striving to make the most of every day.
MJC has been engaging in campaigns aimed at reducing CO2 to help prevent global warming.
By participating in the newly launched “Fun to Share” campaign, we will make further contributions toward the creation of a low-carbon society through energy savings and the promotion of eco-friendly activities, in order to prevent global warming.

Initiatives in business operations

Effluent treatment system at Aomori Factory

MJC's Aomori Factory has installed a process effluent treatment system created by the Pentagon so that the industrial effluent discharged from the production manufacturing process does not impact Aomori's rich natural environment. Useful metals such as gold are used in the production of probe cards, and small amounts end up in the industrial effluent. We make use of the latest heavy metals processing technology to collect these precious metals.
Additionally, Aomori Factory has come up with a way to employ a cooling system that uses natural outdoor air in cleanrooms where it manufactures probe cards.
The introduction of these kinds of cutting-edge systems has not only reduced environmental impact compared to the systems that MJC used to use, but has also led to cost savings.

MJC recognizes that sensitivity to the environment on a global scale will become increasingly important as part of its corporate social responsibility (CSR) activities in the future. Accordingly, we will continually carry out environmental measures to reduce resource and energy usage, reduce waste, promote recycling, and properly manage chemical substances.

Aomori Factory given a Fiscal 2009 Director-General's Award for Excellent Energy Conservation Factory & Building from the Tohoku Bureau of Economy, Trade and Industry

The Tohoku Bureau of Economy, Trade and Industry selected MJC's Aomori Factory as a Fiscal 2009 Plant with Excellent Energy Management and gave it a Director-General's Award, the top honor, as a factory having particularly commendable energy management that could serve as a model for others.

The award commended the factory's performance in reducing CO2 emissions by around 20% over two years (3,257 ton/year) through efforts to reduce energy use, such as recovery and utilization of waste heat from cleanroom air conditioning, optimization of control settings for boilers and other equipment according to the season, rationalization of compressor operation, and optimization of lighting equipment's luminance in each room.

Complying with Japan's amended Energy Conservation Act

Japan's Energy Conservation Act*1 requires business operators to monitor energy usage at all their locations in Japan. On October 1, 2010, MJC was designated as a “specified business operator” and the Aomori Factory as a “Type 2 designated energy management factory,” requiring a 1% reduction in intensity*2 per year over all business operations.
In fiscal 2019, MJC's energy intensity was 1.692 kl/kh, down 2.6% from the previous year, and so the target of a 1% reduction was achieved. Going forward we will continue to carry out activities toward the goal of a 1% or greater reduction in intensity. Furthermore, we are committed to maintaining a comfortable working environment and to contributing to energy savings while also giving consideration to the reduction of energy usage during peak hours*3, in association with 2014's Energy Conservation Act amendments.

  • *1Energy Conservation Act: Act on the Rational Use, Etc. of Energy (The amendment took effect on April 1, 2014.)
  • *2Energy intensity: A measure of energy efficiency. The smaller the number, the greater the rise in production efficiency, indicating energy savings and contribution to the prevention of global warming. (MJC's intensity is calculated based on energy usage and total hours worked.)
  • *3Peak hours: 8:00 AM to 10:00 PM in the summertime (July to September) and wintertime (December to March)

Promotion of green purchasing

Japan's Act on Promoting Green Purchasing* promotes proactive procurement of eco-friendly goods and services by national and other public institutions. Based on this law, MJC has practiced green purchasing of office supplies since fiscal 2010, when it specified green purchasing as an improvement initiative common across all its locations. As a result, we have maintained a green purchasing rate of around 90%. Going forward, we will continue contributing to the reduction of environmental impact and the promotion of a social structure enabling sustainable development through green purchasing.
