Mizushima Plant

Introduction to Mizushima Plant[Establishment]
1969[Main functions and products]
A plant to make comprehensive use of C5* fraction extracted from naphtha.
・Isoprene rubber
・Thermoplastic elastomer
Aerial view of the Mizushima Plant

・Petroleum resin
・Synthetic aroma chemicals
・High-performance resin
・RIM molded articles
・Isoprene monomer
・Butadiene monomer* C5

Hydrocarbon molecules containing five carbon atoms. They are the byproduct of thermal cracking, or breaking down, of naphtha, and also include ingredients for raw materials of synthetic
rubber and resin.

Plant Policy (from Plant Manager)
At the Mizushima Plant, we have the slogan “Let’s advance production innovation,business innovation and process innovation with an ABC culture!” and we are making
efforts for this ABC (atarimae, bakashoujiki, and chanto, or in English: to earnestly andproperly perform all of the routine but necessary tasks) culture to take hold and these threeinnovations.
This is because I believe that when each employee properly practices things they havedecided without fail such as procedures and rules based on compliance with the law, thenthis is the starting point for offering stable high-quality products to society with the highest

priority on safety and environmental protection.
In addition, at the Mizushima Plant, we have established the Monozukuri Training Centeras an educational institution for all operators. We accept trainees from each plant, and through conducting basic education forworking in a chemical factory, we train operators that can perform the routine but necessary tasks.
We are working to ensure that the Mizushima Plant meets the expectations of the local community and society at large in its
pursuit of safety and stability, achieved by firmly rooting ABC culture and through the three innovations.

Safety initiatives[Policy]
In order to realize a stable, safe and competitive plant, we will thoroughly tackle all business as production innovations[Concrete efforts]
・Memorial morning note-1-FY2016 CSR Website CSR > Site Reports > Worksites > Mizushima Plant

We distribute a note of past accident dates and use past cases as training.
・4R-KYT* trainer one day training
In order to promote improved sensibility and awareness of danger, we implement this at subcontractors as well as foremployees.
* 4R-KYT
Four-round risk assessment activities One risk prediction method to discuss, think about and understand risk factors in the workplace and in working conditions and the phenomena that cause
them in small groups, in order to solve them before acting. The name 4R-KY comes from the division of the procedure from 1R (round) to 4R.

Efforts to Reduce Environmental Impact[Policy]
In order to minimize environmental impacts, in addition to continuously tackling energy-saving, we promote reduction ofenvironmentally hazardous substances.
[Concrete efforts]
1. Reducing toxic chemical emissions
Since 2002 we have achieved zero atmospheric emissions of butadiene.
We will continue to reduce VOCs** VOC
Volatile Organic Compounds Generic name for organic compounds that exist in the air as gas.

2. Reducing industrial waste
Goal for landfill: 5 tons or lessFiscal 2015 result: 3.5 tons (achieved goal)
We will reduce the amount by implementing efforts including reducing waste, reusing beverage bottles, and recycling plastics as
solid fuels (the “3Rs”), which will lead to reducing final waste amounts.
3. Saving resources and energy
In fiscal 2015, while energy consumption increased accompanying an expansion of production volume, we are reducing theintensity index. Continuing on from the previous year, in fiscal 2014 in addition to stabilizing our processes, we conducted adiagnosis of steam traps throughout the plant in order to plan improvements for defective areas. In addition, our new andefficient combustion and heat recovery boilers began operating from August 2015, and are expected to make ongoingincremental resource and energy savings.
4. Reducing air pollution
We updated our boiler in fiscal 2015.
5. Reducing water pollution
We installed measuring equipment in various places in the wastewater treatment system, and will strengthen our management
through more accurately understanding the processing status.

We carry out education and training at the “Monozukuri Training Center”, the company-wide training institution in the Mizushimaplant site. The Center is a place for education and development of beginner operators that provides guidance on being amember of society and the plant’s stability and safety.

Living Together with the Local Community[Concrete efforts]
1. Community dialogue activities
In an effort to proactively interact with the region, we participated in community-organized events, such as the summer festival
and rice-cake making.
2. Plant tours
On December 17, 2015, we received 30 second graders from Okayama Prefectural Kurashiki Minami High School.
3. Regional volunteering
We have performed voluntary neighborhood cleanups since fiscal 2006.
