Environmental management system
In order to engage in environmental activities in an organized fashion, the Person Responsible for Environmental Management implements integrated management related to the environment, under the direct control of top management. In addition, the company as a whole also engages in environmental activities under the direction of the Committee on Environment. We have organized specific section committees to handle industrial waste and energy saving, and we coordinate environmental management through these committees while seeking further improvements in mitigating our environmental impact. As we strengthen the connection between environmental management and our main business in managing our objectives, we are also supporting the appropriate efforts where changes are taking place, such as newly built business locations, buildings, and production lines.
Environmental Preservation Promotion System
Internal environmental audits
We implement internal environmental audits to check the operational state of our environmental management system. The audit team consists of two to three employees who have completed the auditor training prescribed by the company. The team checks if the environmental management system is being properly operated, maintained and improved. We create audit guidance and hold advance workshops for auditors at some locations in order to improve the quality of the audits.
External environmental examinations
We ask the Japan Quality Assurance Organization (JQA), an external certification
body, to conduct examinations to check if our environmental management
system is functioning properly in accordance with ISO 14001:2015.
In FY 2019 examinations were conducted at the Jinno R&D Center (Aichi Prefecture) and Hanyu Plant (Saitama Prefecture) along with change reviews for expanding the scope of activities. No areas were found to be in need of improvement as a result, and the auditors determined that the system is being maintained. As a general opinion, they pointed out the need to improve the capabilities of each location as the applicable scope of the system is expanding year by year.

The results of INOAC's major environmental efforts in FY 2019 are shown in the table below. In terms of reducing CO2 emissions that result from energy use, the Committee on Energy Saving continued to take the lead in various efforts, which enabled us to reach our targets. In terms of reducing waste disposal, we moved forward in reducing emissions, including recycling and measures against defects. However, we were unable to reach our targets because market conditions for resalable waste have become stricter each year. In terms of reducing emissions of substances subject to the Pollutant Release and Transfer Register (PRTR) system, we were unable to reach our target by a small margin because we transferred and closed several facilities, which resulted in the disposal of waste substances.
Compliance with environmental 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. Through monitoring, measurement, and assessment at each plant, 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 as part of our environmental management system. In accordance with business ethics, we will continue strictly adhering to environmental preservation agreements with local government, including environmental laws and regulations.

Training for emergencies
We identify accidents and emergencies according to the characteristics of each business facility, and periodically conduct training to prevent environmental pollution from fires and chemical leakage (oils, solvents, etc.) from equipment and other facilities. General disaster training was held at the Anjo Plant (Aichi Prefecture) on May 29 and November 26, 2019 and other training is also conducted according to the characteristics of each department, including training for preventing outflows of raw materials and evacuation drills at night. In other facilities, training for emergencies is conducted on a preparatory basis.
Reducing our environmental footprint
Reduce energy consumption
To help to prevent global warming, we have been engaged in efforts to reduce CO2 emissions by promoting energy saving. We made significant revisions to our INOAC Energy Saving Standards, and made efforts to visualize the progress of our energy-saving activities. Major activities in 2019 included thorough heat insulation measures, utilizing heat exhaust from compressors, eliminating air leakage, and applying heat shields to windows.
In 2019, our CO2 emissions resulting from energy use decreased a little--approximately 10% in terms of intensity--compared to 2018.

Utilizing heat exhaust from compressors
Curtaining off areas of workspaces
Key efforts to promote energy saving in 2019
- Insulating buildings using INOAC's thermal insulation board, THERMAX
- Reducing energy usage by utilizing heat exhaust from compressors to heat rooms
- Conducting air leakage patrols and eliminating air leakages at each business location
- Lining windows with INOAC's heat insulation sheet, CELL SHADE
- Installing inverters into cooling tower fans to reduce energy usage
- Curtaining off areas of large workspaces to improve the efficiency of air conditioning
- Switching to LEDs for fluorescent lights and using individual ON/OFF pull switches to save energy
- Installing demand meters and visualizing demand as a measure to address peak energy usage
Other efforts to prevent global warming
INOAC is working on preventing global warming from other perspectives as well. During the summer, we hold our Summer Eco-style Campaign to educate our employees on how to save energy, such as by promoting "cool biz" energy saving attire. We are also engaged in cooperative transport and deliveries (milk runs), a modal shift to railway and maritime transport, and consolidation of distribution bases. Furthermore, we have installed and are operating solar power generation equipment (total installed capacity 5,417 kw/h) in unused spaces on 15 different production plant sites throughout Japan.
Activities to reduce waste
All Committees on Waste Reduction throughout our company take the lead in promoting waste reduction activities. These include cutting back on losses by reducing defects and improving yield; expanding on the use of recycled materials, such as by separating and recycling used paper; promoting sales of the long cushion produced from material remnants (see article on the right for more details); and developing recycled materials.
Activities to reduce the use of environmentally hazardous substances
INOAC uses PRTR substances such as m-tolylene diisocyanate, a raw material for polyurethane foam as well as xylene and toluene which are used in coating processes. We are making efforts to cut back on the amount of these substances we use, release and transfer, such as by implementing alternatives to replace the use of 1-bromopropane as a cleaning agent which we were able to fully accomplish. Conversely, however, there were also increases in the use of such substances arising from new coatings for automotive purposes, so output intensity remained mostly level.

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.Ministry of the Environment
Development and sales promotion of the recycle mat "Pellemat"
Pellemat is the name of a product we sell that is made using the material remnants of rubber sponges produced at our company. They are ﬁrst crushed into chips and then hardened into sheets. Since rubber sponges have an airy layer, the mat is lightweight and demonstrates excellent thermal insulation in addition to reasonable cushioning. Furthermore, the surface is not slippery, which makes it the perfect work mat for factory ﬂoors to alleviate foot fatigue while working. In this way, we are contributing to waste reduction by utilizing what used to be unneeded material remnants that would have otherwise been disposed of in landﬁlls as industrial waste.
Development and manufacturing of the long cushion, a recycled product
We are developing and manufacturing products with material remnants of urethane that we produce, crushed into chips to be used as filling for cushions. With urethane in chip form, cushions exhibit less deformation over long-term use, thus extending the life of the product. Products have longer replacement cycles and produce less waste thanks to longer product life and the use of unneeded material remnants that had been treated as industrial waste.
Managing information on chemical substances
Promoting IMDS, chemSHERPA and more
Information collection through IMDS in INOAC - reporting process and chemical management system
INOAC registers information on chemicals and reports it to our customers through IMDS*1, particularly in the automotive field which is our main field of business. We have a management system to obtain the necessary
information via our supply chain and to register the information into IMDS.
We also collect information and report it to our clients using the chemSHERPA*2 format, which is widely used in the industrial world, especially the electrical machinery industry.
- 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 originally developed to comply with the EU ELV Directive.
- 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.
Creating an in-house database
The Automotive Division is creating an in-house database through which information on chemical substances contained in parts and materials purchased from suppliers is identified based on information about chemical substances, and centrally managed. This has allowed us to be certain of our compliance with laws and regulations on chemical substances and client requirements which increase each year, while also helping to improve the efficiency and the reporting accuracy of information we register in IMDS and when examining the chemical substances contained in our products.
Establishment and implementation of green procurement criteria
We ascertain what chemical substances are regulated by laws, regulations, and by our customers, based on which we create our green procurement criteria - a list of those chemical substances that we should work to reduce. We present these criteria to suppliers and use them to obtain information on chemical substances contained in raw materials to be purchased. We are also consistently monitoring the latest regulatory developments, based on which we revise these criteria once each year.
Communication about chemical substance management
The Global Quality Assurance Division is a company-wide organization for environmental stewardship, which organizes and leads meetings for the chemical substance management sections of each department once every two months. They review the green procurement criteria, check the management system and establish or change its operating rules, and exchange opinions concerning the latest trends in chemical regulations, such as the REACH regulation and RoHS Directive. They also periodically audit the management system in each department to maintain and improve management systems that are appropriate and reliable.
