Continuous quality improvement activities
To ensure customer satisfaction, the CoorsTek KK Group uses quality control implementation guidelines and conducts
quality improvement activities. We identify areas for strengthening quality control and develop quality targets for eachorganization on the basis of customer requirements (Voice of the Customer, or VOC), internal quality trends andgroup-wide evaluation results.

To achieve quality targets,
we implement quality management systems and worksite improvements.
Quality starts with people, and we believe that education and training are the basis of quality. We systematically provide
quality education, conduct SMS activities *1, and work to foster quality awareness among employees. We examine root
causes of events using the 5-why analysis method*2 and implement permanent measures. To raise quality levels, wehave developed six-sigma activities*3 throughout the Company; to prevent the likelihood of quality-related incidents, wehave implemented FMEA*4 and change management; and to enact quality manufacturing, we have introduced the useof SPC*5 methods.
In order to deliver customer satisfaction, the CoorsTek KK Group vigorously conducts quality improvement activities toachieve targets for medium-term management plans using a method of loss rate from quality complaints*6, number ofcomplaints, audit results, and ratings information as quality indicators.

Waste Management
Zero emissions for a recycling-based society based on the 3R concept

Initiatives to achieve zero emissions
Each business site has a recycling center that manages waste and implements zero emissions activities to help realizea recycling-based society. Activities include minimizing defects and material loss by improving manufacturing yield andworking with recycling partners for sludge and scrap waste in accordance with the 3R principles (reduce, reuse,recycle). Quality requirements from customers became more rigorous in fiscal 2017, resulting in an increase of 5.1% of
total waste discharged in relation to direct cost compared to the previous last year.
The final disposal rate of CoorsTek Nagasaki Corp. increased due to an increase in production of raw quartz materials.
On the other hand, Hadano Facility and Oguni Facility achieved perfect zero emissions*1 and zero emissions
respectively.

Management of Chemical Substances“One drop control”*1 policy for managing chemical substances
Chemical substance management measures
The CoorsTek KK Group promotes green procurement and responds to the EU’s RoHS Directive and REACH. We
manage chemical substances subject to the PRTR Law and substances subject to the Poisonous and Deleterious
Substances Control Law, taking into consideration human health and safety, prevention of pollution, and reduction ofenvironmental impact. As we strengthen the implementation of the “one drop control,” we ensure meticulous
management of data on usage, release, and transfer.
*1 “One drop control” is the Group’s practice of meticulous substance management. It involves daily cleaning and inspection so thatno leakage—not even one drop of oil, chemical, or other substance—is overlooked. Structures are designed and maintained toensure easy detection of any leakage. For example, trays and overflow spill basins are kept dry.

Pollutant release and transfer register (PRTR) substances
The main PRTR substance that the CoorsTek KK Group handles is hydrofluoric acid, which is used for cleaning. There
was an increase in the amount of hydrofluoric acid handled and released in fiscal 2017 due to an increase in the
production of raw quartz materials.

Measures to prevent air pollution and offensive odors
The CoorsTek KK Group prevents air pollution and the release of offensive odors by installing exhaust gas treatment
equipment, fuel conversion, and other measures. Each business site has established voluntary exhaust gas standards
and works to reduce environmental impact.

Water pollution prevention
The Group reduces the burden on wastewater treatment facilities through appropriate use of raw materials, abrasives
and chemical substances used in production processes at each business site. The Group has also establishedvoluntary standards at each business site and is strengthening the monitoring of water quality.
In addition, each business site conducts emergency response drills to enable a rapid response in the event of an
