Plant Policy by the Plant Manager
With the motto of “Let’s advance production innovations, business innovations, andprocess innovations with the culture of ABC” (atarimae, bakashojiki, and chanto, orin English: to diligently and properly perform all routine but necessary tasks), we areworking to entrench this ABC culture at Mizushima Plant and achieve these threetypes of innovations.
I believe that the basis for offering products of stable quality while placing thehighest priority on safety and environmental protection is employees’ full andsteadfast compliance with laws and regulations and adherence to the procedures,

rules, and other matters that they have decided.
We have established the Monozukuri Training Center at Mizushima Plant to provide company-wide operator
education. The center accepts trainees from each plant and conducts basic education for working in a chemicalfactory to ensure that Zeon operators can perform the routine but necessary tasks.
We are working to gain the trust of the local community and the wider public with a commitment to safe and stable
operations achieved by entrenching the ABC culture and achieving the three types of innovations at Mizushima Plant.

Safety Initiatives
Safety Policy
As a world-leading plant in the comprehensive use of C5 in integrated production from raw materials to finishedproducts, and with the spirit of contributing to society as provided in Zeon’s CSR Policy and preventing accidents anddisasters as provided in Zeon’s Safety Philosophy, we define our safety policy involving production activities forpetrochemical products as follows.
1. Safety takes precedence over all else. We implement safety measures, identifying the sources of risk andconducting activities to reduce the risks. We conduct thorough safety education and training on an ongoing basis.

Specific Initiatives
1. Reducing emissions of hazardous chemical substances
・We have achieved zero atmospheric emissions of butadiene since FY 2002 and continue to take steps to reduce ouremissions of volatile organic compounds.
2. Reducing industrial waste
・Final landfill disposal target: 5 tons or less
・We are reducing the amount of waste we generate, reusing beverage bottles, and recycling plastics as solid fuels.
3. Conserving resources and energy
・Process stabilization
・Inspecting steam traps throughout the plant
・Improving unsatisfactory areas
4. Reducing impacts on water quality
・Strengthened management of treatment conditions (installed measurement devices in the wastewater treatmentsystem)
5. Environmental data＊”0” indicates less than 0.5 tons, and “0.0” indicates less than 0.005 tons
