Message from the President
We make the world measurably better.

On October 1, 2015, we changed our name from Covalent
Materials Corporation to CoorsTek KK.
When US-based CoorsTek, Inc. acquired Covalent’s shares in
December 2014, the two companies proceeded to integrate theirpersonnel, technologies and other assets. The first phase of
integration was completed in October 2015, after which the new
Company began activities as a key member of the CoorsTek
Group.
Founded in 1910, CoorsTek is one of the world’s foremost
manufacturers of advanced materials and a leading provider ofengineering solutions. CoorsTek KK was founded in 1918 as afurnace materials manufacturer, so both companies havecentury-long histories and traditions.
President and CEO

The integration of the two manufactures has resulted in a

CoorsTek KK

company with more than 50 manufacturing sites and 6,000
employees in 14 countries on four continents, serving more than
10,000 customers, and doing business in virtually all majorindustrial sectors.
We will continue to prioritize ties with all of our stakeholders, strive
to create products that benefit society, and faithfully fulfill our social
responsibility in order to meet stakeholder expectations.
I hope that this report deepens your understanding of our CSR
activities. I ask for your continued guidance and encouragement in
the coming years.

Environmental activities
The CoorsTek KK Group regards environmental protection as a key management issue. We are engaged inenvironmental protection activities on a continual and voluntary basis, and these guided by the Environmental Policy
we established in 1989.

CoorsTek KK Group Environmental Policy
The CoorsTek KK Group works to bring together materials, technologies and people to create new values. In carryingout our activities, we promote environmental protection in the belief that the Earth’s resources are invaluable.
Accordingly, we promote the following management concepts:（1）Position environmental protection as a critical issue at the heart of our business.
（2）Adhere to environmental laws, environmental guidelines embrace by CoorsTek KK Group, andother voluntary environmental protection standards.
（3）Reduce the environmental impact of our business activities and prevent pollution.
（4）The Group has voluntarily set action plans such as energy conservation to help prevent global warming,
including policies such as zero emissions through the effective use of resources and the reduction of the use ofchemical substances.
（5）Promote green procurement, including prioritizing the selection of raw materials that have minimal
environmental impact.
（6）Contribute to society by developing and providing superior environmental technology and products,
cooperate with communities, and undertake environmental protection activities in general.

Environmental management structure
We have an integrated environmental◆Environmental Management Organizational Structure

management structure in which the Group
Environmental Committee is the top
decision-making body for matters relating toenvironmental management. All business sites
operate environmental management systems
that comply with ISO14001 requirements.

Environmental internal audits
The Chief Environmental Management Officer and the Environment, Safety &Health Group conduct compliance audits and activity assessments of all
business sites.
We use our standards to confirm whether we are in compliance withenvironmental laws and regulations, and we assess the status of ourenvironmental activities. The Environment, Safety & Health Group follows up
assessment results and works to improve environmental efforts.

◆Environmental conservation effects
Although energy consumption has increased year on year, the rate of increase in energy consumption was lower than
the rate of increase in production, resulting in an energy savings effect. Although water consumption has increased
year on year, the rate of increase was of the same level as the rate of increase in production. Main reasons for theincrease in the amount of waste were due to production increases in and unexpected furnace repairs.

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, including minimizing defects and material loss by improving manufacturing yield and working
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 2014 was 185 tons, or 3.6% of the total amount of waste generated, an 8.9%
reduction from fiscal 2013. This reduction is due to a thorough sorting of waste made possible by innovation thatenables detailed examination of the content of waste for final disposal and sorting the recyclable portion. We willcontinue to promote recycling and further reduce the amount of final disposal.

Management of Chemical Substances“One drop control”* 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 well as strengthening implementation of “one drop control,” we ensure meticulous
management of data on usage, release and transfer.
* 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, pans and dikes are kept dry.

Pollutant release and transfer register (PRTR) substances
The principal PRTR substance that the CoorsTek KK Group handles is hydrofluoric acid, which is used for cleaning.
There was an increase in the amounts of hydrofluoric acid handled and released in fiscal 2014 due to an increase in
new products that had to meet high-purity requirements.

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.

History of Our Commitment to the Environment
Ever since our foundation, we have prioritized harmony with society and the environment in the conduct of business.
We intend to continually strengthen the basis of environmental management with the aim of ensuring sustainable
management*.
* Sustainable management is defined as contributing to the establishment of a sustainable society by practicing corporate
responsibility in economics, social and environmental ways and by respecting people.
