From feasibility to final CBG output — and beyond.

Feasibility study & DPR

Every successful plant starts with honest numbers. We assess feedstock availability within a viable radius, test samples for biomethane potential, and model the project’s economics before you commit capital.

• Feedstock survey, seasonal mapping and supply-chain planning
• Lab analysis: total solids, volatile solids and biomethane potential
• Site selection, soil investigation and topographic survey
• Bankable Detailed Project Report with CAPEX, OPEX and IRR
• Support for lender due diligence and subsidy applications (MNRE CFA)

Approvals & liaisoning

Regulatory delays sink more biogas projects than technology does. Our liaison team manages the permits and agreements so construction starts on schedule.

• SATAT Letter of Intent and offtake agreements with OMCs
• PESO licences for compression, storage and cascade filling
• State Pollution Control Board Consent to Establish and Operate
• CEIG electrical approvals, factory licence and fire NOC
• FOM registration under the Fertiliser Control Order

Engineering & design

Our in-house multi-disciplinary team engineers plants around your specific feedstock — not a one-size-fits-all template.

• Process design, mass balance, PFDs and P&IDs
• Digester sizing, mixing and heating design
• Upgrading technology selection: VPSA, membrane or water scrubbing
• 3D plant modelling, civil and structural design
• Electrical, instrumentation, PLC/SCADA and automation design

Procurement & supply chain

Long-standing OEM relationships let us source reliable equipment at competitive prices, with inspection at every stage.

• Pre-treatment, shredders, agitators and pumps
• Gas holders, H₂S scrubbers, chillers and dryers
• Upgrading skids, CBG compressors and cascades
• Vendor qualification, expediting and third-party inspection
• Logistics, insurance and site material management

Construction & erection

Experienced site teams deliver civil, mechanical and electrical works safely, with daily progress tracking against a baseline schedule.

• RCC and steel digesters, feedstock sheds and roads
• Equipment erection, piping and structural works
• Electrical installation, cabling and earthing
• Planning with Primavera schedules and weekly client reporting
• Rigorous HSE and permit-to-work systems

Commissioning & performance guarantee

Biological start-up is where experience shows. We seed, feed and stabilise your digesters, then prove the plant’s performance against contractual guarantees.

• Pre-commissioning checks, loop tests and hydro tests
• Inoculation, ramp-up and digester stabilisation
• Performance guarantee tests for CBG output and methane purity
• Operator training and complete O&M manuals
• As-built drawings and handover documentation

Complete plant operations & maintenance

Our responsibility doesn’t end at handover. Our O&M division runs plants day to day with guaranteed uptime, so you can focus on offtake and finance.

• 24×7 operations by trained, certified operators
• Feedstock procurement, baling and storage management
• Preventive and predictive maintenance with spares management
• Remote SCADA monitoring and monthly performance reports
• Biology monitoring, lab testing and process optimisation

By-products & offtake support

A profitable plant monetises every output stream. We help you set up the systems and markets to sell them.

• Solid FOM and liquid LFOM processing, drying and bagging
• CBG dispatch via cascades, retail outlets or CGD grid injection
• CO₂ recovery options for food-grade or industrial use
• Carbon credit documentation support
