Performance Snapshot
Unit economics, byproduct value, and illustrative annual profit for 3, 6 and 12 TPD plants at 350 operating days and 100% capacity utilisation.
CBG selling price revised upward from ₹75/kg to ₹105/kg — a 40% increase in modelled realisation. All project economics on this page reflect the revised price.

Byproduct value
A CBG plant also generates digestate in the form of raw FOM and raw LFOM. When appropriately monetised, these byproducts can contribute an additional revenue stream alongside gas sales.

Our unique technology
The system recirculates biogas from the dome and injects it through independently controlled zones. This creates three-dimensional sludge movement without placing rotating equipment inside the digester.



01
A blower draws biogas from the digester dome instead of introducing another process medium.
02
PLC-controlled solenoid valves pulse gas through individual injection zones at defined intervals.
03
Rising bubbles move sludge vertically while shifting injection points create horizontal circulation.
04
The cycle supports uniform heat, better substrate contact, and fewer floating or settled layers.
Why it matters
Conventional pumps and submerged propellers can face corrosion, struvite build-up, and shaft stress. Gas injection moves the process mass with fewer wear points inside the vessel.
Evaluate it for your plantThe injection network avoids mechanical mixers operating directly in abrasive sludge.
Sequenced mixing distributes heat and microorganisms across the digester volume.
Gas-injection studies cited in the technical presentation report energy savings of up to 50%.
The approach is suited to fibrous and high-solids agro-industrial substrates where crust control matters.
Performance depends on digester geometry, sludge characteristics, solids content, operating cycle, and equipment sizing. The cited energy-saving figure comes from the supplied technical presentation and should be validated during project engineering.

Focused topics
Topic 01
Start with feedstock, plant fit, timelines, incentives, and day-to-day operation.
A biogas plant converts organic waste into methane-rich gas through anaerobic digestion. Green Vikalp designs plants that process food, agricultural, and industrial waste, then recover energy, fertilizer, and process water from the same system.
Common feedstocks include cattle dung, agricultural residues, food waste, distillery spent wash, and press mud. These materials can be blended to support stable digestion and improve methane yield.
Yes. Purification and compression systems can upgrade raw biogas into high-purity CBG for transport fuel, industrial burners, or other gas-quality energy applications.
A typical project takes 6 to 9 months from site assessment through commissioning. The final schedule depends on plant capacity, site readiness, statutory approvals, civil work, and equipment delivery.
Central support for CBG now flows through GOBARdhan, India's National Unified Scheme for Compressed Biogas, approved by the Union Cabinet on 6 August 2026 with a ₹23,731 crore outlay for FY 2026-27 to FY 2035-36. It provides capital assistance of up to ₹2 crore per TPD of installed CBG capacity, an administered CBG price of ₹2,110 per MMBTU with a minimum ten-year horizon, and assured offtake through the CBG blending obligation. State bio-energy policies may add location-specific support. Green Vikalp helps prepare eligibility documents and align the project scope with the applicable framework.
Routine work includes monitoring digester biology, checking pumps and valves, cleaning filters, calibrating gas-upgrading equipment, and completing preventive maintenance. Consistent O&M reduces downtime and protects gas output.
Fertilizer output depends on feedstock volume, composition, and the selected digestate process. The recovered digestate can be refined for on-site use or sale, creating value alongside CBG production.
Suitability depends on the consistency of your waste supply, energy needs, available land, utilities, and project economics. Farms, food processors, distilleries, hotels, municipalities, and industrial sites with steady organic waste are common candidates.
Topic 02
Understand CBG offtake, manure products, profitability, and pre-investment decisions.
Green Vikalp can guide clients on industrial demand, applicable government-supported initiatives, gas-quality requirements, storage, and potential offtake strategies. Commercial arrangements vary by project, so each route is evaluated against the plant's location and output.
Yes. Digestate generates raw FOM (the solid fraction) and raw LFOM (the liquid fraction), which can be sold as generated at illustrative realisations of ₹2/kg for raw FOM and ₹0.20/kg for raw LFOM. For a 3 TPD plant this equates to roughly ₹52,000 per day of byproduct value. Further processing, packaging, or branding can add value, but those economics are project-specific.
raw FOM is the nutrient-rich solid fraction left after anaerobic digestion and digestate dewatering. It contains organic matter and nutrients that can improve soil health when processed and used in line with applicable quality requirements.
raw LFOM is the liquid fraction recovered from digestate. It contains dissolved nutrients and can be used as a bio-fertilizer where local agronomic practices and quality requirements permit.
Yes. The model CBG selling price used across this website has been revised upward from ₹75/kg to ₹105/kg. All annual revenue and illustrative annual profit figures — ₹6.02 Cr for 3 TPD, ₹12.04 Cr for 6 TPD, and ₹24.08 Cr for 12 TPD — reflect the revised price at 350 operating days and 100% capacity utilisation.
At the revised indicative CBG selling price of ₹105/kg, the base model considers ₹65/kg of total cost (₹30/kg bank or finance cost, ₹20/kg running expenses, and ₹15/kg contingency), leaving ₹40/kg of CBG profit: ₹105 − ₹30 − ₹20 − ₹15 = ₹40. For a 3 TPD plant operating 350 days a year at 100% utilisation, this implies an illustrative annual profit of about ₹6.02 Cr, including raw FOM and raw LFOM byproduct revenue. These are project-level estimates, not assured returns; actual profitability depends on feedstock security, plant capacity, gas yield, operating efficiency, capital cost, financing, and offtake, and requires a site-specific feasibility study.
Yes. Pre-investment consultancy covers feedstock availability, site conditions, expected gas output, utilities, capital and operating costs, market opportunities, implementation strategy, and key project risks.
Topic 03
See how the project is managed from customized engineering through final commissioning.
Yes. The project team coordinates engineering, procurement, construction, vendors, schedules, budgets, quality inspections, and commissioning. Clients retain one point of contact throughout the EPC lifecycle.
Yes. Equipment selection, digester sizing, utilities, automation, layouts, and expansion provisions are tailored to the feedstock, site, production target, and commercial priorities rather than copied from a standard plant design.
Typical deliverables include process flow diagrams, P&IDs, equipment datasheets, layouts, operating and maintenance manuals, inspection reports, commissioning records, calibration certificates, warranties, and as-built drawings.
Yes. Engineers support equipment checks, calibration, process start-up, biological stabilization, gas-quality verification, performance testing, and operator training until the plant meets the agreed commissioning parameters.
