Compressed Bio Gas
From organic waste to bankable CBG projects
Independent technology selection. Integrated project delivery — turnkey plants, consultancy and partner coordination around feedstock and offtake.
Independent partner
The right technology. The right project.
Turnkey delivery, consultancy and technology integration. Equipment is selected through partners — Saimona is not positioned as a default OEM.
Anaerobic digestion
Reactor choice follows the feedstock
CSTR, plug-flow or dry digestion is selected against solids content — not a catalogue default.
Project pathway
From a residue stream to a defined plant
Consultancy first where the brief is still open. Turnkey when scope, partners and offtake can be locked.
Engineering & integration
One accountable sequence across partners
Cleaning, upgrading and compression have to fit as a train, not as isolated equipment buys.
Fuel specification
From biogas to dispatched CBG
Upgraded gas compressed, stored and delivered to the offtake that the project actually has.
Feedstock
Projects start with what can be digested
Residue, energy crop, livestock, press mud or organics — assessed before technology is chosen.
Secondary vertical
Solar, sized to the business
A second renewable offer — not a distraction from the CBG pathway.

The pathway
Waste becomes a fuel specification
Organic residues and biomass are not a fuel until they have been digested, cleaned, upgraded and compressed to a specification a buyer can use. Saimona’s work is to turn that industry sequence into a project: assessed, partnered, permitted where required, and capable of being financed and delivered — not a catalogue of machines.
Organic waste
Biogas
Biomethane
CBG
End use
01
Organic waste
Residue, energy crop, dung or city organics — characterised before anyone names a digester.
02
Biogas
Anaerobic digestion produces a methane–CO₂ mixture with sulphur, moisture and traces.
03
Biomethane
Cleaning and upgrading raise methane to a fuel specification such as applicable IS 16087.
04
CBG
The upgraded gas is dried, compressed and stored for the offtake the project actually has.
05
End use
Transport, industry, waste treatment or nutrient return — whichever offtake is real.
CBG solutions
Four ways into a project
Sponsors do not all need the same engagement. Some need a study before they spend. Some need a plant coordinated through partners. Some need the technology train selected and integrated. Consultancy is not a sidebar — for many organisations it is the correct first purchase.
Turnkey CBG Plants
Complete project delivery through technology and manufacturing partners, from definition through commissioning support.
A turnkey engagement is for sponsors who want a defined plant, not only a study. Saimona coordinates feedstock logic, process design, partner equipment, installation support and commissioning support. We do not present ourselves as the default manufacturer of digesters or upgraders. Those systems are selected and integrated through partners so the plant matches the site rather than a catalogue SKU.
CBG Consultancy
Technical and commercial guidance before capital is locked to a single flowsheet.
Consultancy is a first product, not a courtesy. Many CBG ideas fail because technology is chosen before feedstock, offtake and regulation are understood. We run feasibility, DPR support, technology shortlists and commercial sequencing so a sponsor can spend capital on a project that can actually be designed and financed.
Technology Integration
Selection and coordination of digestion, upgrading and compression systems suited to feedstock and offtake.
Integration is the work of making digestion, gas cleaning, upgrading, compression and digestate handling operate as one train. Each block has a different water, energy and pretreatment demand. Saimona’s job is to choose and coordinate partners against those demands rather than stack unrelated equipment.
Project Development
Support from concept through planning, partner alignment and execution readiness.
Development sits between an idea and a construction start: concept, feedstock and offtake hypothesis, study sequence, partner alignment and a path a board or lender can read. It is useful when the sponsor has land or residue but not yet a plant definition.
How we deliver
A project pathway, not a product SKU
A CBG plant is a sequence of decisions. Feedstock, offtake, technology partners, engineering, installation and commissioning have to belong to one story. The ten stages below are how Saimona frames that work — the exact commercial model (principal contractor, PMC, or both) is confirmed per project.
01
Consultation
Understand project objectives, offtake intent and the role Saimona should play.
The first conversation is about what the sponsor actually wants: a fuel offtake, a waste solution, a bankable study, or a plant that can be built. We record feedstock, location, stage and constraints so the next work is scoped, not assumed.
02
Feedstock assessment
Evaluate availability, seasonality, quality and collection logic before a flowsheet is frozen.
A CBG plant is only as stable as the material that feeds it. We look at quantity through the year, moisture and contaminants, collection radius and storage — because those facts decide the reactor more than a brochure capacity.
03
Feasibility
Technical and commercial assessment of whether the project can be designed, permitted and financed.
Feasibility tests whether the idea can live as a plant: process hypothesis, utilities, offtake options, digestate path and a cost envelope a board can challenge. It is a decision document, not a sales appendix.
04
Project planning / DPR
Develop the project roadmap, study documentation and decision sequence.
Planning turns a feasible idea into a sequence: studies, partner shortlists, approvals and capital gates. DPR support is written so lenders and sponsors can see the same project, not two different stories.
05
Technology selection
Match digestion, cleaning, upgrading and compression options to feedstock and specification.
Digester type, H₂S removal, upgrading route and compression are chosen as a train. Saimona is not locked to one OEM. Partners are selected against measured gas, water, energy and the offtake specification that will actually apply.
06
Engineering & design
Develop engineering requirements with selected technology and manufacturing partners.
Design work sits with the partners who will supply the kit, coordinated so interfaces, utilities and safety envelopes match. Saimona’s role is to keep the plant one system rather than a set of disconnected packages.
07
Procurement & integration
Coordinate partner equipment so the plant works as one system, not a catalogue of parts.
Procurement is sequenced against lead times and construction logic. Integration means the cleaning skid, upgrader and compressor are specified to the same gas, not bought independently and hoped to fit.
08
Installation
Support plant installation according to the agreed execution model.
Whether Saimona is coordinating partners or supporting a principal contractor is confirmed per project. Installation follows the drawings and the site’s real constraints — access, utilities, monsoon and safety — not a generic Gantt chart.
09
Commissioning
Bring the plant to operating condition against the defined process and safety envelope.
Commissioning is when feedstock, biology and machines meet. Support covers start-up discipline, specification checks and the operating envelope agreed in design — not an implied performance guarantee unless that is contracted.
10
Project support
Technical and operational support after handover, as scoped for the project.
After handover, support is whatever the engagement defined: troubleshooting, O&M advisory, or partner coordination. It is scoped in writing so it is a service, not an open-ended promise.
Technology ecosystem
The right technology. The right partners. The right project.
Digester type, H₂S removal, upgrading and compression are chosen with partners against measured feedstock, gas quality and offtake — not a catalogue SKU. Saimona does not claim to manufacture those machines as a default. We evaluate options, select partners and keep the train coherent so the plant can meet a specification a buyer will actually take.

Feedstock
Projects start with what can actually be digested
Industry feedstocks commonly assessed for CBG. Seasonality, contamination and collection decide the plant more than a brand name. A confirmed Saimona feedstock list will replace this industry set when provided.
Agricultural residue
Straw, stalks and related crop residue. Seasonality and collection radius usually decide the plant more than the digester brand.
Napier grass
A cultivated energy crop, not a waste stream. Land, water and farmer contracts sit inside the project, not outside it.
Press mud
Sugar-mill filter cake. Often co-located with crushing season, storage and mill operations.
Cattle dung
Livestock manure with collection, grit and dilution as the real design constraints.
Food waste
Commercial and industrial organics. Segregation and contamination control determine whether the biology holds.
Municipal organic waste
The organic fraction of municipal waste. Inerts and plastics drive whether wet or dry digestion is even plausible.
Applications
Where CBG is used
Specification CBG is a substitute for fossil gas where a buyer, a quality envelope and a logistics path exist. The four uses below are the conversations we will have. Further applications appear only if Saimona confirms them.
Vehicle fuel
Specification CBG is used as a CNG substitute in transport where the applicable biomethane standard is met.
Industrial energy
On-site or nearby industrial fuel use where offtake does not depend only on a retail-outlet cascade model.
Waste management
Organic residues diverted from dumping or burning, with energy as a product of the treatment system.
Agriculture
Digestate managed as slurry or fermented organic manure where quality, offtake and regulation allow.
Projects
A portfolio, when there is one to show
The cards below are layout placeholders so a portfolio can be reviewed. They are not documented Saimona plants, capacities or yields. When a real project is published it will carry location, feedstock, technology, Saimona’s actual scope and a status the client has approved.
Solar energy
Expanding the renewable energy portfolio
Solar sits beside CBG as a second renewable offering — industrial and commercial arrays when that is part of the brief. It does not replace the CBG pathway on this homepage.
Sustainability
Waste. Resource. Energy. Impact.
CBG captures methane that would otherwise be lost, and can return nutrients through digestate where quality and a buyer exist. This page stays qualitative until verified project data is supplied. Policy context is not the same as a claimed percentage reduction.
Insights
How to read this industry
CBG, biomethane and RNG are the same upgraded molecule in different markets. Policy created demand; it did not create take-or-pay. These notes are written for sponsors who need that distinction before they buy a flowsheet.
Guide
CBG, biogas, biomethane and RNG — the same molecule, different markets
India says CBG. Europe says biomethane. North America says RNG. Sponsors lose time when they treat these as different products.
Technical
What IS 16087 actually means for a CBG project sponsor
The biomethane specification is not a marketing badge. It is the quality envelope your upgrading, compression and offtake have to live inside.
Policy
SATAT, CBO and GOBARdhan — how offtake actually works
Policy created a market. It did not create take-or-pay. Bankable projects treat offtake as work, not as a slogan.
