This report has been prepared to focus on a number of highpriority topics emerging from the environmental efforts conducted by the TDK Group. TDK’s Environmental Report 2000 was compiled on the basis of results recorded by the TDK group as a whole, from April 1, 1999, to March 31, 2000. The report also contains sections relating details of activities taking place from April 1, 2000, on and provides a preview of future activities. Note: References to a fiscal year in this document pertain to the period beginning on April 1 of the year named and ending on March 31 of the following year. Thus, fiscal 1999 covers the period from April 1, 1999, to March 31, 2000. With the arrival of the twenty-first century, we have entered the era of the environment. The era of mass consumption of natural resources through large-scale production and indiscriminate disposal of waste is over. We must strive to become a resourcerecycling society, concentrating our accumulated wisdom on the continuing search for sustainable development based on coexistence with the earth’s environment. For businesses, this new era presents new challenges. We must respond to a business environment that is changing rapidly and becoming more dynamic, so that we can continue to succeed. And at the same time we must ensure that our responses are environmentally sound. TDK’s “Exciting 108” medium-term plan provides a framework that helps us meet both objectives. Established in 1999, Exciting 108 helps us continue to be an exciting, dynamic company and expand our corporate values. And it also sets forth a Zero Emission Strategy to guide us as we actively work toward the realization of a resource-recycling society. Our original target for achieving zero emission was March 2006, but we have decided to move the target ahead two years as trends such as the shrinking number of waste-disposal sites have become more apparent. By March 2004 we intend to be an eco-factory, restricting emissions and reusing materials to the greatest extent possible and converting any unavoidably generated waste into resources through recycling. We have also responded swiftly to the ISO 14001 standard, which establishes criteria for operating facilities in an environmentally sound fashions. We have already obtained certification for all of our domestic production and research and development facilities, and are steadily proceeding with related efforts at our overseas offices. By implementing an environmental management system based on ISO 14001, we are making continual efforts to reduce the environmental impact of our products and operations. In April 1999 we also began to incorporate environmental considerations into decisions made in our production systems. We introduced environmental product assessments and “green purchasing“ into our product development procedures and have initiated a campaign to produce lead-free electronic parts. No company can survive without coexisting with the earth. TDK employees are dedicated to preserving the environment, accepting the challenge to take action now to achieve sustainable development for the future. I hope that this publication will help you to better understand TDK’s environmental efforts and activities. Hajime Sawabe President and CEO 1 Corporate Motto “Contributing to culture and industry through creativity” Corporate Principle Employees attribute “vision,”“courage,”“trust” TDK Environment Charter Basic Principle The global environment is the womb supporting all life forms on Earth. Recognizing this basic principle, TDK is committed in all its business operations to handing over a more wholesome environment to future generations. Basic Policy TDK is committed to a resource-recycling society. All our corporate activities are geared toward this basic policy. We pay attention to the protection of the environment, the conservation of energy and resources, and all other factors that may affect the global environment. Action Program As a good corporate citizen, TDK pursues its corporate motto by operating in a way that constantly considers the effects of its actions on the global environment and natural resources. To this end, we have established the following guidelines; 1. Establish a corporate organization under the leadership of a board director to promote and implement environmental management policies. 2. Uphold all laws and regulations related to the protection of the environment and raise the level of environmental management. 3. Enforce environmental auditing and promote voluntary enforcement of environmental management. 4. Issue environmental management provisions and annual reports on environmental management and constantly update environmental management standards. 5. Create products that are compatible with the company’s policy of reducing the environmental burden on Earth. This requires that we conduct assessments on environmental safety during the product design stage and take both energy saving and resource conservation into account during product development and manufacturing. 6. Undertake environmental management activities throughout the entire TDK Group, including all affiliated companies and overseas manufacturing units. 7. Contribute, as a corporate citizen, to the protection of the global environment. 8. Raise environmental awareness among all TDK employees by means of education and support employees’ participation in environmental activities. Revised in March 1995 Established in March 1993 2 Corporate Set-up for Environmental Protection Each and every one of us dedicated to the same goal Corporate Activities Implemented Across the Board TDK’s structure for driving its efforts to protect the earth’s environment is under the direct authority of the president. Starting with the Corporate Environmental Protection Council, which deliberates and sets the basic direction of the company’s environment-related policies, it spans the entire spectrum of the TDK Group—in all business divisions, corporate functions, and subsidiary companies. We accelerate environmental activities under a company-wide project.

An assessment in the design phase ensures that products with minimal environmental burden are produced. Chemicals in the raw materials and components used in our products are assessed through green purchasing so that environmental impact is part of the selection criteria. And in-plant recycling, an Environmental Management System based on ISO 14001, and other activities minimize environmental burden in the production process. A special logo we created in December 1999 indicates products produced under these environmental impact controls. Product Assessment In 1998, we introduced the TDK Product Assessment System in order to increase the efficiency of low environmental impact products and to promote the use of uniform standards throughout the company. The assessment process starts during the design of new products and continues during each subsequent stage to minimize the environmental burden of our products. We began using the system for domestic development activities in 1999, leading not only to product improvements but also to numerous new products with decreased environmental impact. A program of incentive awards helps to promote the development of new products that are environmentally friendly. In addition, life-cycle assessments (LCA) were conducted for a number of products to determine their quantitative impact on the environment, and companywide introduction of such assessments is under consideration. Many environmentally friendly products developed under the product assessment system were displayed at the TDK TechnoForum 2000, which was held at TDK’s Technical Center in Ichikawa city, Chiba in May 2000 to show TDK’s latest accomplishments, attended by 3,300 visitors. Commendation for environmentally friendly products TDK TechnoForum 2000 held from May 24 to 26 at Yawata Technical Center Exhibition of environmentally friendly products 6 Lead is an essential material used in electronic components to achieve specific properties. At the same time, however, it can also be a hazardous substance. Since our company began 65 years ago, we have worked to create a production process that was lead-free, despite the difficulties involved. For example, through our original technology we have developed lead-free multilayer ceramic capacitors and the world’s first lead-free ceramic resonators. But making products lead-free involves more than simply finding a replacement for lead. It also requires the use of lead-free solder. Since the melting point of lead-free solder is about 50˚C higher than conventional solder, it is also necessary to make the products more heat tolerant. Under a company-wide project we are accelerating our efforts to develop lead-free materials and use lead-free solder. Lead-free multilayer ceramic capacitors Lead-free ceramic resonators DC-DC converter for hybrid vehicle use This converter boasts reduced power consumption achieved through greater conversion efficiency and lighter weight made possible through the use of an aluminum case, thus enabling it to contribute to greater fuel efficiency in hybrid vehicles. Decreased use of hazardous substances Energy conservation Responses to the elimination of lead Environmentally Friendly Products Reusable case for providing components Reduction of waste materials Resource conservation Magnetic heads for HDDs Formerly supplied with tape wound By reviewing the structure of HDD magnetic heads and replacing the double-layer coil with a single-layer coil, reductions in materials and energy during the manufacturing process were achieved. In addition, resources are saved by reducing the number of magnetic disks used in HDDs through higher recording densities. Bulk feeder Usually, electronic components are supplied to mounters one at a time by a tape wound on a reel, and the tape is processed as waste material. The bulk feeder supplied components without the use of tape, contributing to reductions in waste material. Single-layer magnetic head (cross-sectional view) 7 Green Purchasing A shift to the procurement of environmentally friendly products Green Purchasing of Goods for the Production Process We investigate the environmental policies of our suppliers as well as the environmental soundness of materials we plan to purchase using our Green Purchasing Standards. Our investigations on corporate operations are used to identify problems affecting both the suppliers and TDK, and provide a reference for future improvements. The results of the surveys on products are entered into a database and made available to the entire company in order to support the development of goods that have a minimal environmental impact. TDK has released an English-language version of its Green Purchasing Standards in view of the globalization of materials procurement.

Data storage/ Application B division C division The Self-declared Environmental Mark Setting high independent standards TDK’s Own Environmental Mark TDK has created its own environmental mark to make the public aware of the concept of environmentally friendly products and to help promote environmental consciousness by setting environmental goals during the development of new products. Fourteen Areas of Environmental Concern In use since December 1999, the mark identifies the environmental considerations that were taken into account when a product was developed. The 14 specific areas that are included are based on ISO 14021 as well as on original ideas from TDK. Fourteen areas of environmental concern 1. Recycled content 14. Clean (reducation or elimination of substance) 2. Recycled resource use 13. Compostable 3. Recovery energy 12. Disgradable 4. Waste reduction 11. Designed dissassembly 5. Recycled energy consumption 10. Recyclable 6. Recycled water consumption 7. Extended life product Standards for the Self-declared Environmental Mark Mark standards are derived from regulations applicable to all products and detailed regulations applicable to specific products, taking the ISO 14021 standards into consideration. TDK is now developing the internal structure under which LCA can be easily realized for all the products. 9. Refillable 8. Reusable Common standards for the TDK self-declared environmental mark (selected from overall 20 items) 1. Implementation of product assessments 2. Implementation of life-cycle assessments, to the extent that the necessary data is available 3. Non-use of hazardous chemical substances identified by TDK 4. Utilization of green purchasing practices 5. Acquisition of ISO 14001 certification for production facilities 9 Zero Emission Strategy Seeking the greatest possible reduction of environmental impact Efforts in 1999 to Reduce Waste Emissions and Recycle Resources TDK’s goal is to reduce the volume of waste handled by outside waste disposal operators by 60% from fiscal 1994 levels by March 2001 and to increase the recycling rate by 50%. To achieve the goal, each TDK plant has set up a work group that manages the volume of each type of waste-generated process and the cost of disposal. Each plant also administers a manifest as stipulated by the revised Waste Handling Law and promotes the recycling and reuse of resources and the reduction of waste in accordance with the three Rs: reduce, reuse, recycle. Information on the waste material generated by each plant is combined and analyzed in both broad and specific categories. The data we accumulate will enable us to develop ever more finely detailed systems in the future. Examples of recycling efforts Type of waste material More specific categories Recycled materials Ash Ash Cement materials Sludge Sludge Iron manufacturing materials, cement materials Waste oil Machine oil Reclaimed oil Waste solvents Reclaimed solvent, detergent Waste alkalis Waste alkalis PH-adjusted liquid Waste plastic Styrofoam Styrofoam Magnetic tape Rope, netting, concrete panels Film Fuel, carpeting Molded Plastic Cement materials, fuel Cardboard Cardboard Scrap copy paper Toilet paper Scrap paper Newspapers and magazines Reclaimed paper Scrap wood Pallets Solid fuel, boards Changes in total waste volume and ratio of resource recycling Kitchen garbage Organic waste Fertilizer, waste decomposing microorganisms (Total of TDK parent and domestic subsidiaries’ product and development bases) Scrap metal Waste metal Reclaimed metal Cans Iron and aluminum materials Leads and wires Metal fittings, copper wire (Thousand ton) Waste volume Ratio of resource recycling (%) 100 70 60 Waste glass and ceramic Glass bottles 40 50 30 Glass Waste ceramic Reclaimed ceramic materials Dust Ground-up waste Iron manufacturing materials, steel Other Dry-cell batteries Ferrite materials, reclaimed materials 50 Fluorescent lights and mercury lights Recovered mercury 20 10 0 1994 1995 1996 1997 1998 0 1999 (fiscal) Volume of waste generated and an overview of the processing sequence Total waste volume (A) Volume of resources recycled (C) 53,000 t 25,000 t sludge, waste oil, waste plastic Volume of substances processed for disposal (B) Volume of waste handled by waste disposal companies (D) 11,000 t 17,000 t sludge, waste oil, waste plastic, scrap paper sludge, waste oil, waste acids, waste plastic (A) = (B) + (C) + (D) Reducing Waste Handled by Waste Disposal Firms and Recycling In order to promote conservation of resources, TDK established goals concerning reduction of the volume of waste processed by outside businesses and the recycling of resources and is striving to achieve those goals. Volume of waste handled by waste disposal firms and recycling targets Fiscal 2000 Fiscal 2003 Compared to fiscal 1994 60% reduction 100% reduction Domestic subsidiaries Compared to fiscal 1997 30% reduction 100% reduction 2.

Reducing waste Parent company Parent company TDK has set individual targets for its own plants and offices and those of its subsidiaries (satellite companies) in Japan to reduce the volume of waste handled by waste disposal firms and promote recycling. We are also working hard to get each of our affiliates to revise their manufacturing processes and to separate waste materials thoroughly. 10 Promoting Zero Emissions We have initiated a zero emissions strategy, as a basic principles of the new medium-term business project named Exciting 108. The scheduled date for the achievement of our ultimate goal has been moved up two years from the original estimate, to March 2004. All of our domestic plants and those of our subsidiaries are involved in the effort to achieve our goal. We are organizing a Zero Emission Project to implement this effort and formulating a basic plan to promote the project at each location involved. We are improving our manufacturing processes and recycling at every step—efforts that include the acquisition of better waste processing technology and the recycling of all four major categories of waste generated at TDK— sludge, waste oil, waste acid, and waste plastics. We are striving to develop the means to eliminate waste emissions to the greatest possible extent. And we are working to reduce the volume of unavoidably generated waste and to promote recycling outside the company while holding to the basic goal of ultimately achieving a 100% recycling rate and zero emission of waste. Definition of Zero Emission TDK’s zero emissions: Eco-factory-type zero emissions The final target is 100% recycling through reduction, reuse, and recycling of waste matter produced by plants. Target substances: 17 types of substances enumerated in Waste Disposal and Public Cleansing Law Target venues: Sites having or expected to have ISO certification including all 27 subsidiaries Target date: March 31, 2004 Organizational chart for promoting the company-wide zero emission project Methods of promoting zero emissions Facilities and plants Including the 27 subsidiaries Reduce (emissions) Reuse Reduce volume of waste matter Concrete measures to promote reduction and reuse No waste Recycle 100% recycling Use resources efficiently Tie-ups with the recycling business field and progress toward independent business activities concerned with recycling Compliance with the Law for Recycling of Containers and Packaging Japan’s new Law for Promotion of Sorted Collection and Recycling of Containers went into effect on an expanded basis in April 2000, and for TDK, its primary effect is on recording-media products. We have devised a company-wide system to enable us to understand, plan for, and prepare containers and packaging materials having the appropriate weight and other characteristics to comply with the new law. We will continue to improve this system in the future so that we will be able to manage containers and packaging each year in a strict manner consistent with the stipulations in the law. Furthermore, we are also working to reduce the amounts of various container and packaging material we use, and promote recycling. President Project leader (Director in charge of safety and environment) Secretariat Safety & Environment Office Specialty sections Regional general affairs sections Business groups Each plant and satellite Overseas plants Corporate functions Subsidiaries Dioxin Strategy TDK and its domestic subsidiaries operated a total of seven small-scale incinerators that fall within the permissible scope of the Waste Disposal and Public Cleansing Law in 1998, but in 1999 five of them were shut down, and the remaining two are scheduled to shut down by March 2001. Finally we will be able to reduce dioxin emissions to zero. 11 Preventing Global Warming Steady efforts to help the effort to prevent global warming Promotion of Energy Conservation TDK has positioned the control of CO2 emissions through energy conservation at the core of its efforts to prevent global warming and promotes energy conservation activities mainly at its major facilities in Japan. A key element of this is increasing the efficiency of production facilities through improvements in manufacturing equipment. TDK is working toward the goal of achieving a 25% reduction in basic energy units by March of 2011 relative to its total for fiscal 1990. Our basic energy unit totals increased from fiscal 1991 through 1993, but have been decreasing ever since fiscal 1994. Changes in TDK’s basic energy unit (Total of TDK parent and domestic subsidiaries’ product and development bases) Sales (1999 = 100) Energy usage volume (1990 = 100) Basic energy unit (1990 = 100) 130 125 115.7 110.6 125 100 109.9 101.0 102.2 99.7 100 115.3 115 112.8 110 75 105.0 105 100 108.9 108.2108.0 100 100 102.8 101.9 101.5 100.4 99.9 98.5 97.7 97.7 50 96.9 Basic energy unit (index) Sales and energy usage volume (index) 120 95 89.1 90 80 89.0 25 84.4 85 1990 1991 1992 1993 1994 Personnel Training to Promote Energy Conservation The revised Energy Conservation Law came into effect on April 1, 1999, requiring more thorough energy conservation measures in manufacturing. We determined the types of energy conservation measures that would apply to each of our facilities and provided training so that they could be carried out. Meetings were held about the energy-efficient operation of furnaces and air conditioners, for example, as well as on issues directly related to manufacturing processes. Our employees also toured other companies to learn new energy conservation measures and energy management techniques. 12 109.0 108.3 101.1 1995 1996 1997 1998 1999 (fiscal) 0 Introduction of New Energy and Co-generation Systems under Consideration Many of our facilities are located near the coast, which makes them suitable for wind power generation. We plan to conduct surveys of wind conditions at the most appropriate facilities and consider the introduction of clean energy systems that use wind power generation. In addition, we have begun to examine the introduction of a natural gas co-generation system at the Chikumagawa 2nd Technical Center with the aim of reducing CO2 emissions. Preparations are underway for the start of operations in May 2001. Examples of Energy Conservation at Plants (1) Improvements in production and manufacturing processes Development of procedures and improvements in manufacturing processes are promoted through determinations of the Basic Energy Unit and confirmations of product quality. Energy Conservation Measure Plant Effect Introduction of servo press molding equipment that does not use hydraulic power Narita Plant 534 MWh/year Acceleration of heating furnace shipment Inakura Plant 224 MWh/year (2) Use of waste heat Sharing expertise on the use of air conditioning using outside air (cold water manufacturing by using a cooling tower during winter) in the entire company. Energy Conservation Measure Plant Reductions in Greenhouse Effect Gases The Global Warming Prevention Law, which went into effect in April 1999, designated PFC (perfluorocarbon, a type of fluorine solvent), as a greenhouse gas. Because we used PFC in some of our cleaning processes, we undertook a study to reduce PFC volumes in accordance with the law. Instead, the study results led to a change in the structure in some materials, which in turn made a water-wash possible. While our goal had been to reduce PFC emissions by 60% compared to fiscal 1995 levels by March 2011, reductions of 73.0% had already been reached by fiscal 1999. We are also planning to examine the use of substitute materials for the PFCs that are used in product evaluation processes.

TDK, which conducted its first surveys in 1997, was unable to determine its values for 1995. Under the terms of a Voluntary Action Plan Concerning Measures to Limit the Emissions of HFCs and Other Gases in the Electronic Industries worked out by the Electronic Industries Association of Japan, totals for fiscal 1997 are interpreted as equivalent to those for fiscal 1995, and TDK follows this policy as well. 332 Kl/year (fuel oil conversion) (4) Improvements in control methods By actively replacing fluid devices with inverter devices, more fluid volumes have been achieved. Energy Conservation Measure Plant Effect Installation of inverter drier blowers Inakura Plant 187 MWh/year Installation of inverter supply and exhaust systems Akita Plant 140 MWh/year 13 Management of Chemicals Creating strict standards for use and a strong system of control Reflected in Green Purchasing Practices and Product Assessments In 1996, TDK established a set of standards governing the use of chemical substances. These standards, which take into consideration the relevant legal restrictions as well as the hazardous nature of the substance, divide chemicals into the categories shown in the figure below. When new legislation governing the use of chemical substances is enacted or existing legislation is revised, we revise our own standards to make them conform. When new potential hazards and concerns about natural resources were revealed in 1998, a more detailed classification scheme was applied to substances already classified as “prohibited” as well as to those classified as “restricted.” This is reflected in our green purchasing practices and our product assessment procedures, which emphasize the procurement of environmentally friendly materials. Developing Substitute Materials and Promoting Their Use Occasionally, in the interests of research and development or the need to analyze or ensure product quality, the use of a prohibited substance is unavoidable there is no suitable substitute available. In those cases, a strict review is conducted by the TDK Safety & Environment Office. Approval is given only when the review criteria are satisfied and must be renewed on an annual basis. This provides increasingly better management with each passing year. This type of review also serves to promote the development and introduction of alternative technology and substitute materials. In 1999, for instance, our production division stopped using mercury to obtain accurate measurements of density in product quality analysis procedures and switched to a system that uses silicon oil, instead. Thus use of a highly toxic chemical substance was completely discontinued. This not only eased the burden of managing use of the material on a daily basis, but also reduced the amount of harmful waste materials generated, reaffirming the value of the review process to the company. In the future we will work to achieve even greater control over the use of such substances, based on the principle of refraining entirely from the use of hazardous chemical substances, no matter how small the amount. Outline chart of supervision system for chemical substances Classification of chemical substances Supervision Standards for Chemical Substances Classification of chemical substances Prohibited Substances: Substances that are not to be used in either processes or products (130 substances) Restricted Substances: Encouraging reduction in usage volume or shift to less harmful substances (553 substances) Controlled Substances: Substances that do not fall into the above categories (as of April 2000) Prohibited substances: Chemicals whose use is, in principle, prohibited due to legal restrictions or their hazardous nature.

We have held company-wide explanatory sessions and taken other steps to make doubly sure we will be in compliance with Japan’s Pollutant Release and Transfer Registers Law, which was enacted in July 1997 and is scheduled to take effect in April 2001. Figures on the respective amounts of air, water, and soil emissions containing substances addressed by the PRTR Law, along with the quantities of constituent waste substances, are shown in the table below. We are committed to the goal of reducing the overall volume of our emissions of chemical substances by 20%, relative to 1997 levels, by March 2006. The figures for fiscal 1999 show a 6.1% reduction, as well as a 34.6% reduction in the use of methylene chloride, a substance used to clean electronic components. Our goal is to completely eliminate methylene chloride emissions by March 2001, and to this end we are proceeding with efforts to come up with techniques that are not dependent on detergents and are exploring the possibilities for using alternatives.

The scope of chemical substances subject to the surveys was in accordance with the PRTR Law. • Volumes handled and emissions volumes were calculated by making reference to the PRTR Guidelines for Electrical and Electronic Industries, with calculations carried out from activities under the Environmental Management System. *1: TDK began totaling figures for diglycidyter of bisphenol A in fiscal 1999. *2: Total including air, water, and soil emissions. 15 Environmental Management System (EMS) Conducting continuous reviews and raising levels company-wide. Acquisition of ISO 14001 Certification TDK awaited the adoption of standards for acquisition of ISO 14001 standards in June 1996 and made a decision that all of its production and R&D bases would acquire certification. Starting with the acquisition of certification by the Mikumagawa Plant in April 1997, all domestic production and R&D bases acquired certification by April 2000. TDK set a goal of having 19 overseas production bases obtain certification by March 2000, but only 12 were able to do so. The remaining seven plants will continue their efforts to acquire certification, and plans are for all to complete certification by March 2001. Since environmental management is an important issue for company management, we determined that acquisition of certification by Headquarters and service subsidiaries was essential. TDK is currently working to complete certification by March 2001. Reinforcing the Environmental Management System and Raising Effectiveness Under a voluntary plan, TDK has set objectives and targets for each plant and is working to improve environmental management system and enhance environmental performance. We are improving operational management, investigating measures for the prevention and amelioration of emergency situations, and conducting regular testing and training, Since management of risks is essential to receive ISO 14001 certification. We are also calling for increased participation among employees, training in-house environmental auditors, and has completed training for more than 1,500 employees company-wide. TDK has also implemented follow-up training of auditors to raise the level of in-house audits. Since internal implementation of such training is desirable, TDK is developing training curricula and training instructors in order to improve in-house audit structures in the future. Moreover, TDK is encouraging improvement on a company-wide level through the environmental audits by the headquarters. Korea TDK receives ISO 14001 certification in June 1999. SAE Magnetics (H.K.) receives certification in December 1999. Waste fluid recovery training (Kofu Plant). Waste water recovery nighttime training In-house auditor training 16 Preserving the Earth’s Environment at Production Sites Each facility is dedicated toward creating a better environment Care for the Environment When Constructing Buildings When TDK constructs a new plant or other facility, it asks builders to take the environment into consideration in both design and construction phases. For example, while the E2 wing of TDK Technical Center and the D3 wing of the Narita Plant (both completed in 1999) were being constructed, these efforts by both TDK and the builders reduced the environmental burden on nearby residents: 1. Ensuring that leftover materials were disposed of properly 2. Ascertaining the chemical content of construction materials 3. Managing water quality and the use of paints 4. Reducing noise The design of these facilities also called for the use of natural lighting to save energy and for a heating and air conditioning system that makes use of water heated and cooled at night when energy costs are lower and then stored for use during the day. We have created a new storehouse for waste matter at Technical Center in order to better manage the separation of waste materials. Monitoring Water Quality In fiscal 1999 it was discovered that discharges from rainwater drains at the one of our plants had lead concentrations in excess of regulatory levels. An investigation revealed that the equipment that collected particulate matter in exhaust emissions was leaking. The particulates, containing lead, were collecting on the roof and became part of the rainwater runoff discharged from the drains. Measures to prevent the problem were undertaken, and plants and equipment were upgraded and operating procedures improved at other sites as well. Since the improvements were made, tests on rainwater have not detected any lead and there have been no subsequent problems. Soil Clean-up We are in the process of cleaning up the soil around one of our plants where residual concentrations of organochlorine solvents in excess of environmental standards still exist. Thus far, clean-up efforts have lowered the concentration, but not to a level below the acceptable maximum. We are now taking additional clean-up measures. We also continue to do periodic testing and monitoring of the ground water at our other business sites, so no problems arise. Testing and monitoring of ground water Thermal storage air conditioning system at the D3 wing of the Narita Plant Kitchen-Garbage Decomposer At its Chikumagawa Plant, TDK has installed an advanced kitchen-garbage decomposer that uses microorganisms to break down waste matter more completely than ordinary composters. The device decomposes the garbage almost completely into water and air, leaving no residue. Kitchen-garbage decomposer at the Chikumagawa Plant 17 Environmental Activities Overseas Ambitious efforts throughout the world Worldwide Activities TDK is attempting to gain ISO 14001 certification for its overseas plants and is engaged in a variety of other environmental protection activities at these sites. We hope to raise the environmental awareness of all our employees as we carry out these activities. Responding to Globalization Separate collection of waste materials at SAE Magnetics (H.K.) The proportion of TDK’s production that is carried out overseas is increasing from year to year, reaching 57% in 1998. Consequently, in 1999 our Safety & Environment Office presented our environmental policy to facilities in the United States, Europe, and Asia and set up channels for transmitting environmental information among TDK facilities. As a result, all overseas production sites had begun product assessment by March 2000, on schedule. The same process will be undertaken at all overseas production sites established in the future. Our overseas facilities are currently getting ready to start collecting environmental data to determine the environmental burden resulting from company activities worldwide. Meeting at the plant in the U.S.A. Activities in Korea As one facet of its global environmental clean-up campaign based on ISO 14001 targets, TDK Korea undertakes clean-up activities in the Annyang river twice a year. TDK Plant in Luxembourg Wins Environmental Protection Prize Clean-up activities of Korea TDK Co., Ltd. in the Annyang river In 1998 the Luxembourg Chamber of Commerce presented TDK Recording Media Europe S.A. (TRE), with its Environmental Protection Award for the company’s wise energy usage. Since 1996 TRE has been using heat emitted from manufacturing processes to turn steam turbines and generate electricity. An in-house generating system at TRE helps reduce CO2 emissions. 18 Employee Education Raising environmental awareness in each employee Systematic Environmental Education Environment Cards Environmental education has traditionally involved training staff responsible for environmental matters in highly technical aspects of pollution prevention and environmental technology. Now, however, all staff members, regardless of job title or position, need to learn about environmental protection corresponding to each position. Environmental education is currently conducted at each of our plants as part of the activities involved in gaining ISO 14001 certification. Still, we have been concerned that this training process may not be consistent company-wide. As a result, we have begun putting together a systematic education system that will involve (1) providing new employees with environmental training; (2) introducing separate training programs for the various levels of the company hierarchy and for technicians, and coordinating the content of these programs; and (3) setting up the system so that each staff members can participate effectively in environmental protection activities according to his or her position. TDK’s plants engage in a variety of methods to raise the environmental awareness of employees and unify them around environmental concerns. One such method is the use of pocket-sized Environment Cards, on which employees write down the environmental protection activities in which they engage during their day-to-day work. This simple yet popular device used at many of our plants seems to work well in making employees more conscious of the goals of our environmental protection activities. Each plant’s own environmental news and posters placed on walls around our workplaces also help raise environmental awareness. Additionally, to ensure that all our workplaces share the same environmental information and that employees are unified around environmental concerns, the Safety & Environment Office at company headquarters issues a regular newsletter named TDK ECOPLUS. Pocket-sized Environment Cards Environmental education program for the newly-employed Environmental newsletters: the Kofu Plant and Kofu TDK publishes a regular newsletter to remind employees that the environment inside the plant is their environment. TDK ECOPLUS Environmental poster: the AC and B sections of the Narita Plant take turns in creating a poster every other month. They also submit their posters to Narita Plant’s Eco Contest each year. 19 Industrial Safety and Health Ongoing safety and health activities TDK has long operated under the slogan “Safety and health for all human treasures.” We place a high value on the ideals of human dignity and the creation of a pleasant work environment. Accordingly, safety and health activities are ongoing to improve the work environment and eliminate workplace accidents. for floor layout and manufacturing processes, which it uses at some plants. The staff also conducts other activities to minimize unsafe workplace conditions. 94.6.28 1. Safety and Health Education Safety and health education takes place both on and off the job, through programs for new employees, workplace assignment rotation, and specialized training in fields like dangerous materials and highvoltage applications. In case a job accident happened to an employee, he must go through the education before returning to work. 2. Safety and Health Self-assessments TDK workplaces are required to conduct safety and health self-assessments twice a year. These cover 16 categories and 252 items. Any nonconforming items must be rectified immediately, to prevent workplace accidents. 3. Company-wide Safety and Health Analysis Each year, our Safety & Environment Office conducts a company-wide workplace accident analysis for the previous year and notifies each plant where changes need to be made. The plants must then develop and carry out a plan for correcting the problems. In some instances the Safety & Environment Office conducts a reevaluation of the TDK safety and health analysis site. 4. Safety Checks on New Equipment The safety and health staff at our company headquarters has prepared a basic safety checklist, which is used when new equipment is delivered or when equipment is moved from one company section to another. Each receiving office and plant uses the checklist to draw up a more specific check sheet to evaluate the equipment; if the item passes, a seal of approval is affixed. This approval system has served to reduce potentially hazardous working conditions dramatically. The safety and health staff has also developed check-up and approval protocols 20 Equipment with a seal of safety approval Various other activities are carried out to ensure the safety and health of company employees. As stipulated by the Industrial Safety and Health Law, each plant has a Safety and Health Committee, which acts as an advisory body on all matters of safety and health management. The departments responsible for safety and health at company headquarters provide assistance as needed.

Community Activities Do what you can around you TDK has adopted “good corporate citizenship” as a fundamental principle, since no company can grow without the cooperation of local and international communities. The following are examples of TDK’s environmental protection activities carried out as part of its get-to-know-you and other community work. Kofu Plant Opens Rose Garden to the Public Many TDK facilities are graced with rose plants, and one site, the Kofu Plant, opens its rose garden to the public when the flowers are in full bloom. The idea behind a rose garden began 20 years ago, when TDK’s president sent a rosebush to the facility, and the staff responded by forming a Rose Committee to enhance the grounds with “the scent of roses.” People come from all over Japan to see the garden when it is open, and local residents much appreciate the beautiful touch to their city. The Kofu Plant’s rose garden has received numerous awards, and in 1997 won the Seventh Urban Beautification with Flowers Contest (corporate division), sponsored by the Ministry of Construction. Pine Preservation Club The remains at Kujuku Island, in Akita Prefecture, are well known for beautiful pine trees. The area is part of the village of Kisakata, mentioned prominently in seventeenth-century haiku poet Matsuo Basho’s Oku no Hosomichi; the picturesque island was largely destroyed in an earthquake in 1804. Unfortunately, however, the pines have begun to die off in the past several years, prompting the formation of a Kujuku Pine Preservation Club in 1999. TDK employees are active volunteers in the club’s efforts. Environmental Management Activities for the Community at Large Thanks to TDK’s emphasis on gaining ISO 14001 certification as quickly as possible, the company has been asked by Akita Prefecture and the cities of Saku and Hita to participate in government policymaking on the environment. We have responded willingly to these requests and also help our clients with the ISO 14001 certification process. The rose garden at Kofu TDK is open to the public. The Pine Preservation Club conducts a survey of dead pine trees. TDK participated in the 20th Environment Symposium held in Kosaka-cho, Akita Prefecture in November 1999. Other Activities Our employees are active volunteers in clean-up and beautification projects in the neighborhoods around their workplaces and at nearby rivers and seashores. Cleaning activities on the Shizunami Coast, Shizuoka Prefecture 21 Environmental Costs For greater efficiency in environmental protection Basic concepts for calculating costs in fiscal 1999 (1) Costs will be determined at the production and R&D bases of TDK and its domestic subsidiaries. (2) Calculations will be made based on Environmental Agency guidelines. (3) The amount of capital investment in plant and equipment shall be the amount paid in fiscal 1999. (4) Depreciation for equipment is not included in cost calculation. The Reason for Ascertaining Environmental Costs TDK is working to determine environmental costs with the objective of gaining an accurate understanding of the expenses necessary for its corporate activities taken in consideration of environmental preservation, so that it can make managerial decisions to promote more effective environmental preservation activities. As one of the means to determine environmental costs, TDK newly created a special accounting code for a part of environmental costs in October 1999. Future developments In the future, TDK will consider the relationship between environmental costs and the reduction in environmental impact as well as profitability and will consider the introduction of an environmental accounting system.
