Business Division Notice: Amvats CBG is a specialized CBG and Bio-CNG business vertical under AMVATS ENGINEERING & TECHNOLOGIES, engineering turnkey commercial anaerobic digestion, biogas upgrading, and biomethane facilities across India.
Setting up an industrial Compressed Biogas (CBG) facility in India is a multi-disciplinary infrastructure undertaking spanning biochemical engineering, mechanical and civil construction, regulatory approvals, and fuel distribution logistics. A standard 5 TPD to 10 TPD commercial facility typically requires between 12 and 18 months from initial land acquisition to commercial gas flaring and cascade sales.
As the specialized bio-energy execution vertical of AMVATS ENGINEERING & TECHNOLOGIES, Amvats CBG provides end-to-end Turnkey EPC (Engineering, Procurement, Construction) and PMC (Project Management Consultancy) execution across Bihar and India.
The 6-Phase Industrial Implementation Roadmap
Phase 1: Project Conceptualization & DPR Formulation (Months 1–2)
- Biomass resource survey within 25–40 km of proposed sites.
- Proximate/ultimate substrate testing and mass-energy balance calculations.
- Preparation of Bankable Detailed Project Report (DPR).
- Submission of Expression of Interest (EOI) under the SATAT initiative to secure a Letter of Intent (LOI) from Oil Marketing Companies (IOCL, BPCL, HPCL, GAIL).
Phase 2: Land Acquisition & Statutory Approvals (Months 2–5)
- Acquisition of 4 to 8 acres of industrial or non-agricultural land with clear road access for heavy transport.
- Obtaining Consent to Establish (CTE) from State Pollution Control Board.
- Change of Land Use (CLU) approval and local Gram Panchayat/District Magistrate NOCs.
- Grid connectivity sanction and industrial water allocation clearances.
Phase 3: Financial Closure & Government Subsidy Filing (Months 4–7)
- Debt sanction from scheduled commercial banks or IREDA under priority sector lending.
- Registration on the national unified portal for MNRE Central Financial Assistance (CFA).
- Structuring long-term EPC and equipment supply contracts.
Phase 4: Civil Engineering & Structural Construction (Months 6–12)
- Biomass storage yards, covered sheds, and drainage networks.
- Deep foundation works for heavy Continuous Stirred-Tank Digesters (CSTR).
- Construction of feedstock preparation pits, pre-digester tanks, and pumping stations.
- Digestate handling lagoons, decanter centrifuges, and FOM drying yards.
Phase 5: Mechanical & Electrical Equipment Erection (Months 10–14)
- Erection of insulated digester tanks with double-membrane gas holders.
- Installation of raw biogas conditioning trains, biological desulfurization, and chiller units.
- Integration of high-precision polymeric membrane gas upgrading skids.
- High-pressure 250-bar gas compressors, cascade filling manifolds, and PLC/SCADA automation panels.
Phase 6: Commissioning, Biological Seeding & PESO Sign-off (Months 14–16)
- Final inspection and operational licensing by the Petroleum and Explosives Safety Organisation (PESO).
- Biological inoculant seeding using active anaerobic digestate or ruminant cattle manure.
- Gradual substrate ramp-up monitoring volatile fatty acid (VFA) to alkalinity ratios.
- Achieving vehicular-grade >96% methane purity and commercial cascade dispatch.

Frequently Asked Questions
A 5 TPD CBG plant typically requires 4 to 6 acres of land. If utilizing dry agricultural residue like paddy straw requiring large seasonal storage yards, 6 to 8 acres is recommended to satisfy PESO safety setback distances and firebreak requirements.
Because Compressed Biogas is compressed to 250 bar (3,600 psi) for storage and commercial transport, the facility falls under the Gas Cylinders Rules and Static and Mobile Pressure Vessels (SMPV) Rules administered by PESO. Operational licensing is legally mandatory prior to filling cascades.
