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

To check whether the Environmental Management System is being operated in line with the stipulations of ISO 14001 (2004 version), we request inspections by the Japan Quality Assurance Organization (JQA), an outside certification organization. In FY2015, we had an inspection conducted, including an expanded inspection of the Ibigawa Plant of INOAC Housing & Construction Materials Co., Ltd. The findings identified no matters for improvement, and JQA judged that the system was being maintained properly. The overall assessment, however, was that a review of environmental aspects at points of variation, as well as assessment of the methods of achieving environmental goals and verification of the effects were necessary.

The following table shows the results of the main environmental activities conducted at INOAC in FY2015. As for energy consumption, we achieved a reduction of approximately 10% from the previous year by upgrading each type of equipment to the latest energy-saving models or taking power-saving measures. As for the amount of waste treatment, although we further advanced reuse and conversion to fuel, we were unable to achieve our goal owing to disposal of scrap material and backup stock, etc., not linked to production activities at the time of equipment handover and changes to materials. However, we will continue reducing waste and proactively promote recycling activities.

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

At INOAC, we identify emergency and accident scenarios according to the characteristics of individual plants and implement periodic drills to prevent environmental pollution and the spread of contamination, such as leaks of oils, solvents, and other chemical substances from fires and equipment. On May 27 and December 1, 2015, we conducted overall emergency drills at the Anjo Plant. In addition, we implement training to prevent leaks of raw materials, nighttime evacuation drills, and other individual training suited to the nature of each section. We conduct emergency training at other business sites as well in preparation for emergencies.

Reducing Environmental Load

Reducing Energy Consumption

Plant Sites Energy Consumption (in a crude oil equivalent)

10% reduction from the previous year

We have already been promoting CO2 emission reduction and energy-saving to prevent global warming. Specific activities include setting energy-saving goals for summer (June to September) and winter (December to February), as was done in FY2014. We replaced equipment that had high energy consumption with the latest energy-saving models (inverter- type compressor, electric-type injection molding machine, etc.) and promoted introduction of LED lights, solar power, etc. As a result, we achieved a reduction of approximately 10% compared to FY2014.

Waste Reduction Activities

Handling amount of Class 1 Designated Chemical Substances(PRTR Law)

6% lower than the previous year

As for waste reduction activities, we hold company-wide meetings, report cases of reduction of waste, and share the information horizontally. As countermeasures against waste sources, we have been working toward the inline use of recycled materials, change or reduction of secondary materials such as packaging, ensuring the return of wooden pallets, etc., used in shipping, expanding utilization as recycling sources through sorting, and use of exhaust gas as fuel through drying and pulverization. As a result, the amount of waste treatment has been trending down over the past few years. Although there was an increase in FY2015 over FY2014, we achieved approximately a 10% reduction compared with FY2012.

Environmental Load Reduction Activities

Amount of waste treatment

Waste disposal volume 2015 3,475

At INOAC, we use chemical substances defined as Pollutant Release and Transfer Register (PRTR) as stipulated in the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management. Thereof, such as m-tolylene diisocyanate, which is a raw material of polyurethane foam, and xylene or toluene used in coating procedures. We have been reducing such chemical substances by replacing some of them with non-inclusion types and reducing loss by improving yield. As a result, the amount of handling of such substances is trending down, and in FY2015 we achieved a reduction of approximately 6% compared with FY2014.

Control of Chemical Substances Information

Promoting the use of IMDS

Information collecting of IMDS at INOAC: flow of reporting and the system of controlling chemical substances

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

INOAC registers chemical substances information and reports to it our customers utilizing IMDS*1 in particular, in the field of automotive components which is the main business of INOAC as a comprehensive manufacturer using polyurethane, rubber, and resin. Since we introduced IMDS in February 2003, we have collected the necessary information through our supply chain and established management systems to implement IMDS registration. We conduct one-on-one instruction and study sessions targeting persons in charge of environmental matters at each technical department to use IMDS effectively, ensure the reliability, and streamline the process. On such occasions, we share the information and issues and solve the problems.

  • IMDS stands for International Material Data System. It was developed database system using the Internet to transmit and collect information on materials and chemical substances in the automotive industry to correspond to EU End-of Life Vehicles Directive.
  • REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals. It entered into force on 1 June 2007. It requires a wide range of management and correspondence such as transmitting information on Substances of Very High Concern included even in molded items.

Constructing In-house Database

INOAC has developed an in-house database to consolidate information on chemical substances contained in purchased components and raw materials, which was collected mainly through an investigation of the supply chain. The database has been operated in the Automotive Department since the end of 2007. It enables us to immediately retrieve information required at the time of registration in IMDS and research whether or not the object contains environmentally hazardous substances. Further, it prevents us from conducting redundant research, leading to a more efficient workflow and contributing to improvement of the accuracy of reports.

Corresponding to REACH

In addition to components molded for automotive use, INOAC produces synthesized materials such as polyurethane and rubber for each type of industry. Accordingly, it is necessary to identify information on chemical substances in a wide range of procured items, including each raw material. The Environmental Management Department distributes the latest environmental information such as REACH*2 to the relevant parties internally on each occasion, precisely identifies and shares the information on substances that are of great concern, and collects information on the substances contained in purchased raw materials.

Enactment and Operation of Green Procurement Standards

We create a list of chemical substances regulated by each type of law and regulation and our customers, as well as those that for which the contained amount should be identified and for which efforts should be made toward reduction. We then submit the list to our suppliers as Green Procurement Standards and utilize it to identify information on chemical substances contained in raw materials we purchase. We operate while conducting reviews that take into consideration adherence to REACH regulations and other of the latest laws and regulations.
