Quality, Environmental, and Occupational Health and Safety Initiatives

The Nitta Group created the Nitta Group Code of Conduct, within which maintaining a quality management system (ISO 9001), environmental management system (ISO 14001), and occupational health and safety management system (ISO 45001) are clearly stipulated as part of the Group’s CSR activities. Then, Nitta created "Nitta Group Quality, Environmental, and Occupational Health and Safety Policy". Moving forward, the Nitta Group will continue to pursue ongoing improvement in its quality, environmental, and occupational health and safety performance, together with activities that maintain a constant focus on compliance.

Quality Initiatives

In order to pursue ongoing quality improvement, Nitta acquired ISO 9001 (quality management system) certification in June 1998 and, then, transferred to the 2015 version (ISO 9001:2015) in January 2018.
As a company suppling to the global market, Nitta incorporates ongoing quality improvement into every stage from product planning and development to manufacture and sales, and undertakes efforts aimed at improving customer satisfaction.

Environmental Initiatives

Global Warming Prevention Policy
  1. 1. Nitta endeavors to reduce CO2 emissions at all of its business and production sites in order to contribute to the fight against global warming.
  2. 2. Sites that use large amounts of energy are prioritized when carrying out CO2 reduction efforts.
  3. 3. Nitta is expanding the scope of its CO2 reduction efforts to subsidiaries, affiliates, and other related companies.

In order to promote environmental preservation efforts, Nitta acquired ISO 14001:1996 (environmental management system) certification in March 2001 and, then, transferred to the 2015 version (ISO 14001:2015) in January 2018. Nitta’s environmental preservation efforts include energy and resource conservation, waste reduction, and VOC (volatile organic compounds [e.g., toluene]) reduction. Also, Nitta undertakes green procurement in line with the EU’s chemical substance regulations (ELV directive*1, RoHS directive*2, REACH regulation*3) and works to be GHS (globally harmonized system of classification and labeling of chemicals) compliant.

  • *1 ELV directive: Directive dealing with the recycling and disposal of used automobiles.
  • *2 RoHS directive: Directive stipulating usage restrictions on specified toxic substances in electrical and electronic devices.
  • *3 REACH regulation: European Parliament and European Council regulation enacted in the EU that are concerned with the management of chemical substances in order to protect human health and the environment.
Power Consumption Reduction

Power Consumption Reduction

Together with electricity and energy-saving initiatives, such implementing air conditioner temperature control, upgrading to high-efficiency transformers, and installing co-generation facilities, Nitta has implemented ongoing, across-the-board energy reduction efforts (gas, steam, heavy oil, etc.) at all of its business sites in Japan, in line with environmental management and the revised Act on the Rational Use of Energy. Each business site has been made more energy-efficient in a variety of ways, such as by upgrading to energy-efficient air conditioners, and changing lighting to LED. Nitta continues to pursue different means of reducing power consumption and overall energy usage.

CO2 Emissions Reduction

CO2 Emissions Reduction

As a result of our continued efforts to save energy, CO2 emissions in fiscal 2018 were slightly down from the previous year. The overall, long-term trend in Nitta’s CO2 emissions has been downward. Nitta will continue to pursue different means of reducing CO2 emissions.

Waste Plastic Reduction

Waste Plastic Reduction

Waste plastics increased in fiscal 2018 after China banned its imports for environmental reasons. However, excluding external factors, the calculation will be lower than in the previous year, and emissions per production value are on a downward trend. Of the 3Rs (reduce, reuse, recycle), the most important is reduce (i.e., produce less waste). Within the production process, Nitta is continuously working to improve quality and yield while reducing waste. Nitta will continue to pursue different means of reducing waste plastic.

Solar Power Installation

In fiscal 2015, Nitta installed solar power systems at the Nara, Nabari, and Kyoto Plants. These systems generate enough electricity to power 220 average households.

Occupational Health and Safety Initiatives

In order to reduce work-related accidents and injuries, Nitta put in place a risk assessment-focused occupational health and safety management system (OHSAS 18001) and acquired certification in January 2004 and, then, transferred to ISO45001 in January 2020. Nitta is strengthening its Safety and Health Promotion System through health risk reduction efforts by chemical substance risk assessment, and disaster prevention and Emergency response training for all types of disaster.

Establishment of "Safety Dojo"


"Safety Dojo" was established at the Nara Plant in fiscal 2018. Nitta develop the ability to predict danger (sensibility) by experiencing fear and danger through the realistic reproduction of disasters that actually occur on the site using safety experience devices. It is used to raise safety awareness and establish and instruct safety measures.
