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 take steps such as revising checklists to emphasize efforts toward goal achievement and compliance in order to improve the quality of the audits.

External environmental examinations

The Japan Quality Assurance Organization (JQA), an external certification body, conducts examinations to check if our environmental management system is functioning properly in accordance with ISO 14001:2015.
In conjunction, expanded examinations were conducted in FY 2020 at the Kira Plant and the Kyushu INOAC Yukuhashi Plant. No areas were found to be in need of improvement as a result, and the auditors determined that the system is being maintained. Issues pertaining to legal and regulatory compliance efforts and corrections to non-compliant matters were addressed in the overall findings.

The results of INOAC's major environmental efforts in FY 2020 are shown in the table below. In terms of reducing CO2 emissions resulting from energy use, the Committee on Energy Saving continued to take the lead in various efforts. However, fluctuations in production volume due to the COVID-19 pandemic resulted in lower production efficiency and we were unable to reach our targets. In terms of reducing waste disposal, we moved forward in reducing emissions, including recycling. However, we were unable to reach our targets because market conditions for resalable waste have become stricter each year. Volume of PRTR substances released decreased from the previous year due to progress in replacing materials that contain these substances and other efforts, although not enough to achieve our goal.

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 resulting from earthquakes, fires and leakage of oils and raw materials. Disaster prevention trainings planned for spring and fall at the Anjo Plant (Aichi Prefecture) were cancelled due to the COVID-19 pandemic, but spill prevention training was conducted in manufacturing sections on November 12, 2020. In other facilities, training for emergencies and urgent circumstances is conducted on a preparatory basis.

Reducing our environmental footprint

Reduce energy consumption

Energy use and Energy use intensity

To help to prevent global warming, we have been engaged in efforts to reduce CO2 emissions by promoting energy saving. Specific measures being taken include covering material drying ovens with heat insulation sheets to reduce energy loss from heat escaping, installing inverters into cooling tower fans to reduce energy usage, and using thermal insulation boards to insulate buildings. Our CO2 emissions resulting from energy use in FY 2020 decreased by approximately 10% compared to FY 2019, and decreased slightly in terms of intensity.

Key efforts to promote energy saving in 2020

  • Insulating buildings using INOAC's Thermax thermal insulation boards
  • 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 Cell Shade heat insulation sheets
  • Installing inverters into cooling tower fans to reduce energy usage
  • Curtaining off areas of large workspaces to improve the efficiency of air conditioning
  • Reducing energy loss from heat escaping by covering material drying ovens with heat insulation sheets
  • 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

Activities to reduce waste

In terms of waste reduction, the company-wide Committee on Waste Reduction leads efforts to improve our rate of product commercialization by reducing defects and increasing yield, and to reuse more material cutoffs. Our waste treatment amount in 2020 was 5% lower than in 2019. While our measured units of waste treated decreased, we were unable to reach our target. We are working toward reducing emissions by expanding sales of the long cushion (see article at right) made from material cutoffs, commercialization of products made from recycled materials, and other such efforts.

Activities to reduce the use of environmentally hazardous substances

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. To reduce the amount handled, released, and transferred of these substances, we have made progress in replacing dichloromethane and bis phthalate plasticizer (2-ethylhexyl) which is partially left over as foaming agent, and we were able to reduce release and transfer amount as well as the output intensity of the substances compared to the previous year.

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 polyurethane that we produce, crushed into chips to be used as filling for cushions. With polyurethane 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

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, 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.

Environmental Communication

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 in order to maintain and improve management systems that are appropriate and reliable.
