Corporate Message

Message from the Company
We make the world measurably better
As a global engineering ceramics manufacturer with a 100-year history, the CoorsTek Group
contributes to a world in which we can feel measurable achievements. Through development
based on the direct needs of a wide range of customers and markets in many business areas, wewill continue to provide even better products.
At the same time, we practice our corporate philosophy, which is to "place the highest
consideration on human safety and environmental conservation.” We believe that environmental
conservation, health, and safety are key elements to continuing our business, therefore we
contribute to the development of society through a variety of activities.
In 2018, all facilities completed the transition to ISO14001, the current 2015 version of the Annual
Environmental Management System, an internationally recognized standard for environmental
management systems. Furthermore, activities aimed at zero emissions significantly improved
total emissions per unit compared to the previous year. In 2019, we continue to promote effective
use of resources, reduce chemical substances, and mitigate global warming to reduce theenvironmental impact of our business activities.
In the area of safety and health, we have been evaluating ergonomics. This year, we are conducting
evaluations of remaining facilities to improve risks identified at all workplaces and create work
environments easier to work in from a scientific and technological standpoint. In addition, as part ofour KY*1 approach, we are introducing the CoorsTek Group’s common 4-Sight (foresight) *2, whichfurther enhances our safety culture by evolving our conventional KY and KYT approaches.

Over the next 100 years, we will continue to grow our business and improve our corporate value.
We will also promote various activities to ensure stakeholder satisfaction. We ask for yourcontinued guidance and encouragement.

help realize a recycling-based society. Activities include 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).
Fiscal 2018 resulted in a decrease of 14.6% of total waste discharged in relation to direct cost compared to theprevious year. The final disposal rate of CoorsTek Nagasaki Corp. increased due to an increase in productionof raw quartz materials. On the other hand, Hadano Facility, Oguni Facility, and Kariya Facility all achieved
zero emissions.

Management of Chemical Substances“One drop control”*1 policy for managing chemical substances
Management of Chemical Substances
Chemical substance management measures
The CoorsTek KK Group promotes green procurement and responds to the EU’s RoHS*1 Directive and
REACH*2. 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 of environmental impact. As we strengthen the implementation of the“one drop control*3,” we ensure meticulous management of data on usage, release, and transfer.
*1 RoHS (Restriction of Hazardous Substances) Directive: European Union directive to restrict the use of lead, mercury,cadmium, hexavalent chromium, and certain brominated flame retardants (PBB, and PBDE) in electrical andelectronic equipment.
*2 REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) Regulation: European Union regulation
mandating registration, evaluation, authorization, and restriction of the use of chemical substances*3 “One drop control” is the Group’s practice of meticulous substance management. It involves daily cleaning andinspection so that no leakage—not even one drop of oil, chemical, or other substance—is overlooked. Structures aredesigned and maintained 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 2018 due to anincrease in the production of raw quartz materials.

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 established voluntary standards at eachof the sites 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.
CoorsTek Nagasaki held a joint emergency response
training with chemical suppliers and waste disposal companies.
