Research Consortium involving the MCG Selected for the MLIT’s B-DASH Project (FY2023) to Demonstrate New Wastewater Treatment Technology for Increased Energy Efficiency and Reduced Greenhouse Gas Emissions
April 17, 2023
The Mitsubishi Chemical Group (the MCG Group) hereby announces that the research consortium composed of Mitsubishi Chemical Corporation, Kubota Corporation, and Tokyo University of Agriculture and Technology has been selected for the Breakthrough by Dynamic Approach in Sewage High Technology (B-DASH) Project (FY2023), run by the Ministry of Land, Infrastructure, Transport and Tourism, to demonstrate the wastewater treatment technology submitted.
The selected submission is for a survey project using membrane aerated biofilm reactor (MABR) wastewater treatment technology for increased energy efficiency and reduced N2O emissions. In accordance with the B-DASH Project’s demonstration category standards, a feasibility study will be conducted regarding the following two issues:
The MABR technology uses a gas-permeable membrane on which biofilm is formed, enabling the direct delivery of oxygen to the attached biofilm through the membrane. The demonstration system employs the proprietary gas-permeable membrane developed by the MCG by leveraging its high gas permeability and biofilm formation control techniques.
The MCG will continue to strive to reduce greenhouse gas (GHG) emissions, aiming to contribute to realizing a sustainable society while providing high value-added functional products.

Launched in 2011, the Breakthrough by Dynamic Approach in Sewage High Technology (B-DASH) Project is run by the Ministry of Land, Infrastructure, Transport and Tourism of Japan to support demonstrations of sewage/wastewater management technology. The project aims to accelerate the research and development as well as commercialization of new technologies in order to build low-carbon, recycling-oriented sewage service systems, reduce life cycle costs, improve anti-flood and anti-aging functions, and facilitate the overseas expansion of Japan’s water management industry.

In accordance with the B-DASH Project’s demonstration category standards, a feasibility study will be conducted regarding the following two issues:
- Demonstrate and confirm the effect demonstrated by the MABR wastewater treatment system (using the MCG’s gas-permeable membrane) for increasing energy efficiency and reducing N2O emissions
- Confirm the MABR technology’s performance during the demonstration, evaluate the effect to be achieved by the demonstration system when applied to retrofit/replacement projects for reducing CO2 emissions, and assess product marketability
