SusBDe and its partners are pleased to announce the successful launch of cold commissioning at the Nagpur Compressed Bio Gas (CBG) Plant, an important milestone in the development of one of India’s most advanced biomethane installations. The hot commissioning will follow in three phases and materialise in March 2026.
Key-numbers: daily processing of 1,000 MT per day increasing to 1,500 Mt per day of MSW and a productioncapacity of 27 million m3 biogas per year.
The start of cold commissioning marks the completion of construction and the transition toward functional testing of all mechanical, electrical, control and safetysystems. This phase ensures that each subsystem performs according to design before the plant moves to hot commissioning and first gas production.
Site Visit & Technical Review
During the commissioning event, senior representatives from the municipality, industrypartners, and technical teams visited the project site. Using a detailed scalemodel, the delegation reviewed the complete process flow—ranging from feedstock handling and anaerobic digestion to gas upgrading and grid-ready CBG output.

These visual elements highlight the scale and engineering depth of the project.
A Fully Integrated Biomethane Platform
The Nagpur plant includes:
- Large-capacity anaerobic digesters
- Gascleaning and upgrading units
- Automated feedstock reception & preprocessing halls
- A dedicated electrical substation and utilities block
- Flares and safety systems engineered to European standards
This facility is built on SusBDe’s standardized, replicable blueprint for industrial biomethane plants—combining technology, operational reliability and efficient commissioning practices.
Strategic Collaboration
The project is being developed in partnership with the Nagpur Municipal Corporation, Keva SusBDe Biotech Pvt Ltd and SusBDe India as well as WTT from the Netherlands. All based on the SusBDe blue-print approach to enable scalable solutions for pan India.
This milestone reflects a shared commitment to sustainable urban waste management and to accelerating India's transition toward renewable, domestically produced green energy.
Next Steps
Following successful cold commissioning, the project will proceed into:
1. Hot commissioning, including biological seeding and process heat-up
2. System integration testing
3. First gas production and upgrading to CBG
The plant is expected to become a significant contributor to the region’s renewable gas-supply and a benchmark for future CBG developments across India.
SusBDe’s partner Pelican Biogas is advancing a portfolio of six poultry-waste-to-biogas plants in Arkansas, with SusBDe supporting the technology and process design. Each plant converts ~100,000 tons of waste into 35+ million m³ of biogas annually, applying the same technology platform used in Europe. With first operations expected in 2027, the portfolio illustrates how proven European systems enable large-scale circular energy solutions in the U.S.
Nagpur’s flagship CBG plant has entered cold commissioning, validating all core systems of a facility capable of treating up to 1,500 tonnes of MSW daily and generating 27 million m³ of renewable biogas each year. With construction complete, the project now moves into operational testing—an essential step toward one of India’s largest biomethane production hubs.
SusBDe joined the Dutch Trade Mission at IFAT India 2025 in Mumbai, presenting its Waste-to-Energy concept and engaging with partners and government leaders on advancing circular solutions in India’s growing sustainability sector.
This week, Jaap Veenenbos and Harshavardhini Varagunan represent SusBDe, it partners at the Dutch biogas sector at IFAT India 2025 in Mumbai. From the Netherlands Pavilion, they are meeting with partners, project developers, and investors to showcase how Dutch technology is driving India’s circular energy transition.
Prof. Joseph Stiglitz, Nobel Prize–winning economist, engaged in in-depth discussions with Bastiaan Dijkman of SusBDe. His perspectives on inequality and climate change resonate strongly with the challenges SusBDe faces: developing profitable, scalable projects that still struggle to secure government and institutional financing. These exchanges underscored both the urgency of action and the need for persistence in building a fairer, more sustainable future.
