Bio-CNG plants · engineered by Biofics
Turn organic waste into bankable clean fuel.
Biofics develops feedstock-led Bio-CNG infrastructure—from feasibility and process design to manufacturing, purification, commissioning and operational support.
Why Biofics
Engineering depth from feedstock to filling.
We connect biology, equipment, controls and gas upgrading so the plant is designed for dependable everyday performance—not only successful commissioning.
Feedstock-led engineering
Characterisation, yield modelling and pre-treatment choices shape the process before equipment is specified.
In-house capability
Process systems, critical equipment integration and manufacturing control reduce fragmented responsibility.
Performance continuity
Commissioning, training, monitoring and support help protect gas quality and output over the plant lifecycle.
The conversion pathway
One connected system. Five protected outcomes.
Each stage is engineered to prepare the next—protecting biological conversion first, then purification and compression.
Secure the feed
Plan reception, storage and contaminant control around actual incoming material.
Condition the slurry
Size reduction, mixing and controlled pre-treatment create a consistent digester feed.
Protect biology
Stable anaerobic conditions convert organic matter into energy-rich raw biogas.
Upgrade the gas
Remove moisture, H₂S and CO₂ to reach the required product-gas specification.
Compress and dispatch
Compress, meter and route CBG for cascades, dispensing or the defined offtake route.
Feedstock reference
Start with what arrives every day.
Indicative yields help frame opportunity; project design must use representative feedstock testing, seasonal availability and the intended operating regime.
| Feedstock | Indicative biogas potential | Indicative Bio-CNG potential | Design priority |
|---|---|---|---|
| Cattle dung | 40–60 m³/tonne | 15–20 kg/tonne | Slurry consistency |
| Food waste | 120–140 m³/tonne | 45–55 kg/tonne | Contaminant removal |
| Press mud | 100–110 m³/tonne | 35–40 kg/tonne | Seasonal storage |
| Napier grass | 110–130 m³/tonne | 40–45 kg/tonne | Size reduction |
| MSW organic fraction | 70–90 m³/tonne | 25–30 kg/tonne | Segregation quality |
Indicative industry reference ranges only. Actual output depends on feedstock composition, volatile solids, pre-treatment, retention time and operating conditions.
Purification that protects value
Gas quality is engineered—not assumed.
The upgrading train is selected around raw-gas composition, required recovery, product specification and the project’s operating economics.
Moisture and H₂S management
Protect downstream equipment and media by stabilising gas before separation.
Integrated VPSA upgrading
Separate CO₂ and other impurities while targeting dependable methane recovery.
Instrumented product quality
Analyse composition, dew point and operating parameters before compression and dispatch.
Project responsibility
From opportunity to operating asset.
A clear delivery pathway prevents gaps between civil works, process equipment, utilities, commissioning and long-term operations.
Feasibility
Feedstock, land, utilities, logistics, outputs and commercial constraints.
Engineering
Process basis, mass balance, plant layout, equipment and project interfaces.
Build & commission
Manufacturing, installation coordination, cold trials, inoculation and ramp-up.
Operate & support
Training, monitoring, maintenance planning and performance improvement.
Project questions
Clarity before capital.
A technically credible project begins by resolving the decisions that control feedstock, land, output and operational responsibility.
