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.
Photos from the visit show:
1. The model explanation illustrating the integrated SusBDe process design
2. The main digestion domes and flare system ready for commissioning
3. Officials initiating the first switch panels to activate cold commissioning
4. The site infrastructure, including preprocessing sheds and electrical yard
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.
What began as a vision in 2021 has become one of India's leading municipal waste-to-biomethane projects. The Nagpur project demonstrates how perseverance, international collaboration and innovative technology can transform ambitious ideas into reality. As the project moves towards completion, it not only marks a major milestone for SusBDe and its partners, but also establishes a blueprint for the next generation of circular economy projects across India.
Following recent high-level meetings with key stakeholders in Sri Lanka, SusBDe has taken another important step towards the development of sustainable waste-to-biomethane infrastructure. During a presentation to the Maharagama Urban Council, SusBDe demonstrated how its integrated MSW-to-CBG technology can transform municipal waste into renewable energy while supporting Sri Lanka's circular economy ambitions.
SusBDe has taken an important step in advancing its sustainable waste-to-biomethane initiatives in Sri Lanka through high-level discussions with the Embassy of the Kingdom of the Netherlands. The Embassy has expressed strong confidence in SusBDe's innovative Dutch technology and will actively support the company's engagement with government authorities and strategic partners to accelerate the development of future renewable energy projects.
SusBDe strengthens its Advisory Board with the appointment of Bert Jägel as Chairman. The renewed Advisory Board will play a more active role in supporting the company's international growth, strategic development, and long-term mission in circular waste-to-energy and biomethane infrastructure.
'TEMPORARY UPDATE: Safety and security of our people in India remain our highest priority. As a precautionary measure, SusBDe has temporarily adjusted selected public team information while continuing all operations and commitments unchanged.
SusBDe attended the 60th anniversary edition of IFAT 2026 in Munich together with representatives from the SusBDe Group of Companies, Keva SusBDe Biotech and SusBDe India B.V. The visit focused on developments in waste segregation, PSA and membrane technologies, biomethane solutions and strengthening relationships with international partners, suppliers and technology providers.
SusBDe welcomes Mr. Sunil Kumar Bains as India Representative, bringing over 37 years of experience in Oil & Gas, CGD, and renewable gas infrastructure to drive SusBDe's expansion in the Indian bioenergy market.
