Service 01 — Compressed Bio-Gas
From feedstock to fuel. One partner.
From feedstock assessment and technology selection to EPC, commissioning and operations, we take projects from concept to commercially viable production.
What it is
Biogas becomes a fuel
when you take the CO₂ out.
Agricultural residues, press mud, Napier grass, cattle dung, food waste and other organic materials can become more than waste — they can become a source of renewable gas.
Through anaerobic digestion, organic matter is converted into biogas. That gas is then cleaned, upgraded, and compressed to produce Compressed Bio-Gas with methane content suitable for CNG-equivalent applications.
But technology is only one part of the equation. The real question is: does the feedstock work?
A commercially viable CBG plant depends on reliable volumes, consistent quality, seasonal availability, sensible transport distances, and a secure offtake strategy. That's where we begin.
Scope of Work
Concept to commissioning,
and then the years after.
Anyone can supply equipment. The difficult part is the sequence — approvals that gate construction, feedstock contracts that gate financing, and a design that has to survive both.
Feasibility & Feedstock Survey
Mapping what is actually available inside a viable haulage radius, season by season, and pricing it honestly before anything is designed.
Process Design & Engineering
Digester sizing, retention time, loading rate and upgrading route selected against the specific feedstock mix — not a catalogue configuration.
Licensing & Statutory Approvals
Consents to establish and operate, explosives and PESO clearances, environmental compliance and the coordination that keeps them on the critical path.
Financial Structuring Support
Bankable project reports, capex and opex models, subsidy positioning and support through lender technical due diligence.
EPC Delivery
Civil works, mechanical erection, gas systems, electrical and instrumentation, delivered under a single point of accountability.
Commissioning & Operations
Digester seeding and stabilisation, performance testing against guarantees, operator training, and ongoing O&M for the assets we run.
What's in the plant
Technology &
equipment.
Every CBG plant we deliver is built from the same set of systems — the choices are which digester and which upgrading route fit the feedstock, not whether the system exists.
Digestion
CSTR or Plug Flow
The digester is selected against the feedstock — a continuously stirred tank for wet, pumpable material, or a plug flow reactor for higher-solids and fibrous material that a CSTR cannot pump or stir efficiently.
Cleaning & upgrading
H₂S removal to CBG
Desulphurisation protects everything downstream, then CO₂ is separated by water scrubbing, pressure swing adsorption or membranes before the gas is compressed for cascade filling or grid injection.

Primary product
Compressed Bio-Gas
Clean, upgraded renewable gas produced from organic feedstock and supplied for CNG-equivalent applications or eligible gas-grid injection.
Co-product
Organic Fertiliser
The nutrient-rich material left after biogas production can be processed into FOM and LFOM, creating useful organic fertiliser for agricultural use.
Co-product
Carbon Credits
Eligible projects can convert verified emission reductions into carbon credits, creating an additional opportunity to monetise environmental impact.
