For the environment


Results of environmental activities

We will ensure compliance with laws and regulations so that the global and natural environments are properly preserved and future generations can inherit a rich global environment. At the same time, we will meet the expectations of our stakeholders and local communities by promoting energy conservation, reducing greenhouse gases, promoting green procurement, reducing waste, and promoting recycling in our business activities.

Initiatives to reduce environmental impact

Promoting energy conservation and reduction of greenhouse gas emissions

  • Business classification system based on the Energy Conservation Act

    We have been evaluated as S class (business with excellent energy conservation) in the business classification evaluation system (for submission in fiscal 2020) based on the regular reporting of the Energy Conservation Act conducted by the Ministry of Economy, Trade and Industry.

    2018 2019 2020
    Most recent year-on-year change in energy intensity 91.7% 101.3% 95.6%
    Average over five years 89.2% 93.0% 94.5%
    Class S S S
  • Energy conversion to liquefied natural gas (LNG)

    Since 2009, the Harima Plant has been operating its boilers using liquefied natural gas (LNG) in place of heavy oil to mitigate CO2 emissions. In 2011, we registered for the domestic credit system certification* (currently the J-credit system) and transferred a total of 15,000 tons of CO2 reduction between 2010 and 2017.
    By utilizing the generated credits, we promote low-carbon investment and expand Japan's greenhouse gas emission reductions.

  • Energy conservation activities

    • We have set up an Energy Conservation Committee to promote energy conservation on an ongoing basis.
    • We visualize the performance of electricity and steam for efficient energy management.
      We are also taking a step forward to show the real-time status of each building and the status of target achievement at a glance.
    • We are continuing our activities to reduce energy loss by reliably identifying and eliminating leaks from the steam piping system.
    • The Ministry of the Environment selected the Harima Plant's project as an ASSET project to reduce CO2 emissions by installing high-efficiency water-cooled heat pump chillers and high-efficiency lighting.

  • Reducing environmental impact by increasing productivity, a characteristic of microbial fermentation

    At the Fukuchiyama Plant, enzymes are produced through microbial fermentation.
    By microbial breeding and fermentation process improvement, the yield of enzymes can be increased several times or several dozen times.
    This increased yield can reduce the number of production runs required and significantly mitigate the environmental impact (energy and waste used by the facilities). Therefore, we have set ISO 14001 targets and are actively working towards them.

Promotion of recycling

We are practicing the 3Rs (Reuse, Recycle, Reduction) of chemicals used in the manufacturing process of semiconductors and flat panel displays by controlling the concentration of ingredients to extend the life cycle, reducing the volume of chemicals used, and reusing used chemicals through distillation. In addition, in cooperation with Nagase & Co., we have set up an on-site chemical production plant and recycling plant in Green Front Sakai. This initiative has been certified as a Resource Productivity Innovation Plan by the Ministry of Economy, Trade and Industry.

Promotion of green procurement

The basic principle for the management of hazardous chemical substances at our company is not to allow prohibited substances into our offices/factories, that is, not to manufacture prohibited substances and not to purchase raw materials containing prohibited substances.

We have established an organization specializing in chemical substance management to comply with domestic regulations and various laws and regulations, including the EU RoHS Directive and industry and customer requirements. We are working to reduce the environmental impact of our products by voluntarily reducing or eliminating the use and discharge of chemical substances where there is concern about their environmental risks.

Biodiversity conservation

The activities of people and companies have a variety of impacts on local ecosystems. As part of our efforts to create a safe, secure, and warm society where people can live comfortably, we have long sponsored local greening projects.

To fulfill our responsibility to conserve the environment of rivers, their watersheds, and the sea, we have always maintained a strict level of control over wastewater discharged from the Harima Plant.

Environmental education

We conduct regular training for all employees every year to educate them about ISO 14001 and the environment. We also provide necessary training in a timely manner, such as new employee training, training by job level, and when laws are revised.
