Reducing our Environmental Footprint

The Shindengen Group is committed to reducing its environment footprint. We focus on managing activities that address global warming, the proper use and disposal of chemicals, safe waste disposal and water-use reduction as well as protecting biodiversity and shrinking our environmental footprint.
The following introduces our FY2019 main activities, including practical case studies.

Reduction of carbon dioxide emission volume

The Shindengen Group is striving to reduce its carbon dioxide emissions in ways that are optimized to each Group company’s circumstances.
Domestic Shindengen Group companies participate in the “Low-Carbon Society Action Plan” that was formulated by the electric and electronic machine industry as a voluntary action plan. They engage in activities improve equipment and improve the energy efficiency of production processes with the aim of improving energy intensity by at least 1% on average per year.
As part of these efforts, Akita Shindengen reduced annual CO2 emissions by 256.4 tons in FY 2019 by installing heat pumps in the air conditioning facilities and appropriately managing the number of boilers in operation that use heavy oil as fuel. In addition, each domestic and overseas Shindengen Group company is striving to reduce CO2 emissions by engaging in various energy-saving activities, such as switching to LED lighting, turning off equipment not in use, improving production equipment and processes, and enhancing air conditioning effectiveness.

Contributions to a low-carbon society

To help create a sustainable society and promote de-carbonization as targeted in the Paris Agreement, the Shindengen Group will continue to deliver eco-friendly products while proactively striving to reduce greenhouse gases emitted when products are used and helping resolve issues specified by United Nations Sustainable Development Goals, a set of universal targets to be pursued via international collaboration. In addition, we agree with initiatives to alleviate and adapt to the impact of climate change being promoted by regional communities and are staunch supporters of relevant activities.
Shindengen’s Hanno factory contributed a CO2 credit equivalent of 11,482 tons on March 19, 2020 to Saitama Prefecture as part of its participation in the “Zero Carbon Saitama initiative” related to carbon offsets. Regarding these CO2 credits, based on the “Saitama Prefecture Global Warming Countermeasure Promotion Rules” and “Saitama Prefecture Goal-Oriented Emission Trading Program”, Saitama Prefecture recognizes the results of greenhouse gas emission reduction activities implemented over the last five fiscal years for which there is data (2010 to 2014) as an extra reduction amount. For the most part, we were able to utilize the results of these repeated efforts in activities carried out by regional communities.

Initiatives to preserve water resources

To address the global issue of declining water resources driven by growing populations and climate change, the Shindengen Group needs to promote sustainable water resource conservation initiatives, including water recycling.
As for water resource conservation initiatives, the Group is taking various measures adapted to the local environments and operational situations of each domestic and overseas company.
Since its founding in 2014, Shindengen India has utilized rainwater to conserve a maximum of 400 m3 annually. Rainwater that falls on the factory’s roof is diverted through gutters into storage tanks. After being treated, the water is used to water plants and to flush toilets. When the factory was built, a 5-m3 rainwater storage tank was installed, and, in 2019, a 60-m3 rainwater storage tank was added.
In addition, Shindengen Philippines works to recycle water and maintains a recycling rate of at least 23%.
Steam used to heat treated water for semiconductor cleaning processes is collected as water by the heat exchanger and fed back into the boiler. Furthermore, treated factory wastewater is reused in the heat exchanger that is used to collect steam, which means that water resources are recycled twice, once in the heating process and once in the collection process.

Awards Received

Akita Shindengen receives Energy Management Excellent Operator Award

Every February, which is energy conservation month, the Tohoku Economic Bureau, Energy Conservation Center, and Tohoku Seven Prefectures Electric Power Use Committee give awards to operators whose energy conservation initiatives serve as models for those of other operators.
Akita Shindengen was awarded the Energy Management Excellent Operator Award at the recommendation of Akita Prefecture Electricity Use Committee. The company was praised for its efforts to rationalize energy use through the following activities over the three-year period from 2016 to 2018 and its remarkable results for improving productivity and promoting energy conservation.

  1. FY2017: Reduced A heavy oil consumption by replacing refrigeration units at the Asuka factory
  2. FY2018: Reduced electric power consumption by switching the internal lighting to LEDs at office entrances at the Oura factory
  3. FY2018: Reduced electric power consumption by installing large compressors at the Oura factory

Chemical Management

The Shindengen Group is committed to appropriately managing chemicals that are used in the manufacturing process and contained within our products and has established the “promotion of chemical substance management” as part of its environmental policy.
The Chemical Substance Management Committee (consisting of Shindengen Hanno Factory employees and the domestic Group companies) regularly share with Group companies, the latest information regarding domestic and international laws and regulations related to REACH, EU RoHS Directives, the Act on Preventing Environmental Pollution of Mercury, green procurement and nonfluorocarbon equipment.
In accordance with the Act on Preventing Environmental Pollution of Mercury, the scope of legally regulated products using mercury will be expanded on January 1, 2021. With this in mind, we are systematically replacing equipment that uses mercury by introducing alternatives with no mercury content. However, we have found it difficult to replace some equipment used in manufacturing facilities. We aim to develop in-house technologies to be mercury-free within 10 years of the enactment of the law.
