Mizushima Plant

The Mizushima Plant is located in the Mizushima Coastal Industrial Zone of Kurashiki (population: 430,000) in the Setouchi region of southern Okayama Prefecture, an area which enjoys a mild climate. Operations began in 1969 as the production base for general-purpose polyvinyl chloride resin. Additional facilities were subsequently added, including a butadiene monomer extraction plant (C4-GPB plant), an isoprene monomer extraction plant (C5-GPI plant), and facilities for C5 related products such as isoprene rubber, synthetic aroma chemicals and specialty plastics.
ZEON's development of the C5 business has been marked by unprecedented achievement in the world due to the success of ZEON's own GPI process. The Mizushima Plant is a major production site representing Zeon's strength in the C5 business.
The Mizushima Plant, which has acquired ISO9001 and 14001 certifications, involves all employees in Total Productive Maintenance (TPM) and promotes Total Quality Control (TQC) across the entire company. The Mizushima Plant will continue to produce useful products of excellent quality, with safe operation as its top priority.
