Environmental performance data (fiscal 2018): major kinds of emissions and their distributions by business site

Scope: This data is based on the data gathered from the following 23 bases.
  1. Denka’s six plants (Omi/Omuta/Chiba/Shibukawa/Ofuna/Isesaki Plants) and one laboratory (Denka Innovation Center)
  2. Six domestic affiliates (Denka Polymer, Denka Seiken, Denka Elastlution, Hinode Kagaku Kogyo, Denka Azumin and Kyusyu Plastic Industry)
  3. Ten overseas business bases (Merbau, Seraya, Tuas, South, Suzhou  (manufacturing/research), Tianjin, Dalian, Vietnam and Malaysia (added in fiscal 2019))
