In 2015, Oguni Facility provided a sumo ring at Inari Shrine, located within the facility, to the Azumazeki sumo stable foruse as a training camp. Families from the community and beyond came to watch the spirited training of professional
sumo wrestlers. The annual Inari Shrine festival also helped deepen relations with local residents, with attractions
including the customary employee sumo competition and stalls operated by local residents and employees.

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). The amount of final waste disposal in fiscal 2016 was 231 tons, or 3.2% of the total amount of waste
generated, resulting in a final disposal rate decrease of 1.2 percentage points over fiscal 2015.

Corporate Social Responsibility Report 2017Management 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 sothat no leakage—not even one drop of oil, chemical, or other substance—is overlooked. Structures are designed andmaintained to ensure 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 2016 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
emergency.

Development of Environmentally Conscious Products and Technologies
Contributing to society through products that are green
Environmentally conscious product development
Contributing to society by developing superior environmental technologies and environmentally conscious products(ECPs) is a key theme of the CoorsTek KK Group.
The CoorsTek KK Group incorporates environmental consciousness in product development throughout product life
cycles from the procurement of parts and materials to disposal.

Environmentally conscious product development example～RCF*1-Free Thermal Insulation for Industrial Furnaces that Can Maintain High Thermal Insulation
Even at Temperatures Higher than 1,000 °C Developed～2

As part of a NEDO* project, CoorsTek KK has developed manufacturing technology for an RCF-free thermal insulation
for industrial furnaces that does not exhibit an increase in thermal conductivity even at high temperatures exceeding
1,000°C. As a result, an energy saving effect of 13% compared to previous insulation materials was confirmed byverifying the thermal insulation properties using an industrial furnace.

Notes

RCF: Refractory Ceramic Fiber. Composed mainly of amorphous alumina (Al2O3) and silica (SiO2) fiber, it is called RCF. It has high thermal
insulation properties and is lightweight and resilient, but it is known that inhalation can cause bodily harm. In November 2015, work that involves
handling RCFs has been designated as work in which specified chemical substances are handled.
