Environmental Management System

The person responsible for environmental management implements the integrated management of the environment under the direct control of top management and implements environmental activities for the whole company in the activities of the Environmental Committee, working to promote environmental activities in an organized fashion. We organized a specific section committee to handle industrial waste and energy saving to further accelerate reduction and to promote environmental management in cooperation with each committee. We also started activities conformable to ISO 14001:2015 in January 2017 and are working to achieve our objectives under a regime close to our main work by completely reviewing manuals.

Internal Environmental Audit

We implement internal environmental audits to check the status of operation of the Environmental Management System. The audit team consists of two to three members who have completed the audit training stipulated by the company. It checks if the Environmental Management System is being properly operated, maintained, and improved. In the event that the team finds that the system is being operated improperly in an organization, it conducts additional audits and corrects the problems so that the system can be operated properly.

External Environmental Examination

We ask the Japan Quality Assurance Organization (JQA), which is an external certification registration body, to implement examinations to check if the environmental management system is appropriately operating in accordance with ISO 14001:2015. We also implemented an examination for shifting to ISO14001:2015 whose activities started in January in FY 2017. As the result, no items indicated for improvement were found, and the system including shifting was determined to be sustained. As an overall assessment, issues to be considered about influence on management in expanding objectives and others were listed.

The results of INOAC's main work for the environment in FY 2017 are shown in the table below.We reduced energy consumption compared with the previous fiscal year even though we could not reach our reduction objectives due to insulation countermeasures in our facilities. Although we moved forward on recycling, we did not reach our objectives for reducing waste disposal because the market standards for valued resources have become stricter year after year. About the release amount of PRTR substances, we introduced CO2 foaming equipment to reduce methylene chloride as a foaming agent, promoted substituting a cleaning agent with non-PRTR substances for a cleaning agent with PRTR substances, reached our objectives and substantially passed it.

Compliance with environment-related laws and regulations

At INOAC, we identify environmental laws and regulations that are relevant to our business activities and manage them on a daily basis. As part of the Environmental Management System, we prevent environmental pollution and otherwise conduct environmental risk management to ensure that we properly comply with laws and regulations related to noise and industrial waste treatment, through monitoring, measurement, and assessment at each plant. We will continue strictly adhering to environmental preservation agreements with local government in line with corporate ethics, including environmental laws and regulations.

Emergency Drills

We identify accidents and emergencies in accordance with the characteristics of each business facility, and periodically mplement training to prevent environmental pollution such as fires and chemical leakage (oils, solvents, etc.) from facilities. General disaster training was held on June 2 and November 30, 2017, and individual training is implemented in accordance with the characters of departments including training for preventing raw materials from flowing out and evacuation drills at night in the Anjo Plant. In other facilities, trainings for emergencies are implemented as preparation.

Reducing Environmental Load

Reducing Energy Consumption

Plant Sites Energy Consumption (in a crude oil equivalent)

10% reduction from the previous year

INOAC has promoted reducing CO2 emissions and saving energy to prevent global warming. We implemented efficiency increases in dryers and room heating by utilizing waste heat from boilers and fans, heat insulation measures on factory roofs, boiler piping, cure furnaces and more, and promoted LED use. The amount of energy used in FY 2017 almost leveled off in comparison with FY 2016, and was reduced by approximately 5 percent (crude oil equivalent) compared with FY 2014.

Other work for preventing global warming

INOAC is working on preventing global warming from other perspectives too. We provide our employees with education on power saving including cool biz, which is our energy-saving attire campaign, with summer eco-style campaigns. We also work on cooperative transportation and smooth deliveries, a modal shift to railway and maritime transport, and distribution base intensiveness. In addition, we participate in the CO2 Reduction and Lights Off Campaign propelled by the Ministry of the Environment every year, and implemented the campaign at 10 facilities including our group companies on June 21 (summer solstice) and July 7 (Star Festival) in 2017 too.

Waste reduction

Discharged and moved quantity of PRTR substances

6% lower than the previous year

Regarding waste reduction, the companywide waste reduction committee, as the leader, promotes reports of waste reduction cases, application of such waste reduction to other facilities, reductions in loss by detecting the reductions and improvements in yields and expansion of utilizing recycled resources including recycling by separating used paper and material recycling at each business place. However, the criteria for valued resources have become stricter; therefore, in many cases we had to disposal resources as industrial waste.

Reducing environmental burden substances

Waste treatment amount

Waste disposal volume 2015 3,475

INOAC uses PRTR substances such as m-tolylene diisocyanate, which is a raw material of polyurethane foams, xylene or toluene, which are used in the coating process. We have promoted increases in using paints with low solvent rates (high solid type) and stopped using 1-bromopropane at the cleaning process of a urethane injection machine as work for reduction in handling amounts and the releasing amount of such target substances. Thanks to this work, we achieved remarkable reductions in 2017 by approximately 29% compared with 2016 and by approximately 50% compared with 2014.

NCV project participation

The NCV (Nano Cellulose Vehicle) project was launched by the Ministry of the Environment to improve automobile fuel consumption by weight and CO2 reduction by applying cellulose nanofiber (CNF), which is a light-weight and high-strength next generation material, to the automotive field. Kyoto University leads the project and more than 20 industrial, academic and governmental institutions participate. INOAC CORPORATION has participated in this project from the beginning, evaluated moldability, physical properties and more, and worked to implement practical realization.

Promoting IMDS, chemSHERPA*2 and more

Information collection through IMDS in INOAC - reporting process and chemical management system

From parts / materials maker to INOAC. From INOAC to automobile manufacturer etc.

INOAC registers information on chemicals and reports it to our customers through IMDS*1, especially in the automotive field, which is our main strength, and has a management system to obtain the necessary information via our supply chain and to register IMDS.
Information collection and report to our customers using the chemSHERPA*2 format that has been widely used in the industry, especially in the electrical machinery industry are supported (The format was changed from the previously used JAMP format to the above).

  • IMDS (International Material Data System): A database for transmitting and obtaining information on materials and chemicals over the internet for the automotive industry, which was developed to comply with the EU ELV Directive as a start
  • chemSHERPA: A unified format to transmit information on chemicals contained in products in the supply chain, which the Ministry of Economy, Trade and Industry took the initiative in developing

Establishment of in-house database

The automotive division operates the in-house database through which information on chemical substances contained in purchased parts and raw materials is managed in an integrated manner, which contributes to improved work efficiency, the accuracy of the contents to be reported in the registration with IMDS and the investigation of Substances of Concern contained in the purchased parts and raw materials.

Establishment and execution of green procurement criteria

We list chemical substances regulated by laws and regulations, or customers, and list chemical substances that we should reduce after understanding their content. We show them as green procurement criteria to suppliers; we use such lists to obtain information on chemical substances contained in raw materials to be purchased.

Environmental Communication

Communication about chemical substance management

The global quality assurance headquarters that is a company-wide organization and leader regarding environmental management gathers the chemical management section in each department and meets once every two months. At the meetings, they review the green procurement criteria, check the management system, establish or change operation rules, and exchange opinions concerning the latest trends in chemical regulations such as the REACH regulation and RoHS Directive, as well as periodically implementing auditing the management system in each department to maintain and improve an appropriate and reliable management system.
