In its “Medium-Term Management Plan 2029,” MCC set the reduction of COD (Chemical Oxygen Demand) as a sustainability target related to water resource management, and has worked to reduce COD in wastewater from its chemical plants.
This completed pilot facility aims to establish a cost-competitive, advanced wastewater treatment technology by combining a wide range of solutions that MCC’s production engineering and research departments have refined. By horizontally deploying this technology across its domestic and overseas plants, MCC aim to achieve the COD reduction target for FY2029, and will explore the possibility of commercializing it as a water treatment business in the medium to long term. For FY2029, MCC targets a reduction of 310 tons at its domestic plants and group companies (compared to FY2023).
The main functions of the pilot plant include: (1) Testing under continuous and batch processes; (2) Multivariate testing based on variations in wastewater composition, temperature, and pH; (3) Testing combining wastewater treatment technologies (biological treatment, membrane separation, advanced oxidation process, etc.).
