Japan Biogas Plant Market Share

By feedstock, the bio-municipal waste category records notable growth

Bio-municipal waste is a key contributor to Japan's biogas feedstock mix, along with agricultural residues and energy crops, thus increasing the production of biogas from organic waste. For example, in July 2025, Suzuki Motor Corporation made public the collaboration with dairy partners under the UNIDO Industrial Cooperation Program to produce cow dung biogas and develop supply solutions. This reflects how organic waste streams can be utilized commercially and scaled. It not only deepens the use of municipal organic waste but also acts as a source of feedstock to a wider range of sectors, thus facilitating the deployment of biogas plants that are more resilient and diversified across different sectors.

Energy crops are gradually becoming dependable feedstocks in the Japan biogas plant market, which, along with bio-municipal waste and agricultural residues, can guarantee continuous plant performance throughout the year. In August 2025, Breakthrough Energy and the Japanese government entered a partnership to expedite the commercialization of biomass and associated technologies, among which is the scalable use of crop-based biomass feedstocks. The collaboration combines funds and expertise to advance the utilization of energy crops, support the deployment of biogas facilities, and further attracting investor interest in the renewable fuel value chains.

By digester type, wet anaerobic digestion witnesses increasing uptake

Wet anaerobic digestion technologies are increasingly being adopted in the Japan biogas plant market to process high-moisture feedstocks such as sewage and food waste. These systems are being used in conjunction with dry systems to maximize the organic utilization. In May 2025, IPC (IHI Plant Services) signed a Memorandum of Understanding with MTC OREC, Malaysia, to co-develop biomethane production from anaerobic wastewater treatment technologies that recover methane efficiently using wet digestion. The collaboration between IPC and MTC OREC demonstrates how leading-edge innovations in wet digestion are elevating biogas yields and facilitating the local and global deployment of stable digestion systems.

Dry anaerobic digestion is designed for high-solid biomass such as crop residues and can be supported by wet digestion for liquid wastes, thus increasing the range of plant applicability. In September 2025, NOVATERA GmbH, a joint venture of Nippon Gases and TES Bio-LNG, made an announcement regarding the introduction of on-site biogas processing and micro-liquefaction systems that enable dry digestion and value extraction at plant locations. The availability of such modular solutions provides operational flexibility, allows for higher methane recovery rates, and thus, contributes to the Japan biogas plant market expansion.

By application, heat generation shows robust growth

Biogas heat generation improves the overall energy utilization when combined with power and transportation fuel uses. In June 2025, Tokyo Enesys revealed its Kumamoto biogas power project, which is a 1.6 MW CHP plant that captures heat from organic digestion for onsite uses and district applications, demonstrating biogas integration across combined heat and power solutions. This method raises energy efficiency, helps meet industrial heat demand, and stimulates developments in energy-rich biogas infrastructures.

Meanwhile, power generation continues to be a major application category in the Japan biogas plant market, along with the integration of renewable systems. In November 2025, Osaka Gas Trading and Export (OGTX) decided to purchase about 26,000 Nm of United States landfill-derived biomethane from Archaea Energy, showing the integration of the cross-border supply chain that supports the use of renewable gas in Japan’s city gas networks and thus, strengthening the demand for biogas-based electricity generation solutions. The agreement is a catalyst for investment in biogas value chains that supply power infrastructure and energy security strategies.
