Performance data of each site

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 22 bases.

Denka’s six plants (Omi/Omuta/Chiba/Shibukawa/Ofuna/Isesaki Plants) and one laboratory (Denka Innovation Center)
Six domestic affiliates (Denka Polymer, Denka Seiken, Denka Elastlution, Hinode Kagaku Kogyo, Denka Azumin and Kyusyu Plastic Industry)
Nine overseas business bases (Merbau, Seraya, Tuas, South, Suzhou (manufacturing/research), Tianjin, Dalian and Vietnam)
