From Organic Waste to High-Purity Bio-CNG
BIOPOWER positions its compressed biogas plants as an end-to-end waste-to-fuel platform that starts with feedstock handling and anaerobic digestion, then moves through gas upgrading and compression to deliver a methane-rich renewable fuel stream suitable for transport, industrial use, heating, power-related pathways, and natural-gas-grid-equivalent applications.
The strongest publicly published technical claims are concentrated in the upgrading and compression stages. BIOPOWER states that raw biogas typically contains about 35–40% carbon dioxide, that upgraded gas can reach over 99% methane, that methane recovery across its published upgrader packages is above 92–98%, and that compressor ranges extend from low-pressure service up to 45 bar and high-pressure bottling or filling applications up to 250 bar.
Because the reviewed pages do not publish fixed CBG CAPEX, OPEX, storage-cascade sizing, or named gas-quality standards, this page stays focused on the claims BIOPOWER publicly supports today: modular upgrading, feedstock flexibility, scalable plant architecture, and feasibility-led project development.
Supports food waste, agri waste, straw residues, manure, press mud, and municipal organic fractions.
Public technical content highlights membrane and PSA/VPSA-based purification systems.
Skid-mounted and expandable process architecture is a core public positioning theme.
Feasibility studies, DPR preparation, and policy-aligned project planning are publicly offered.
How a BIOPOWER CBG Plant Works
The reviewed technical pages support a clear process chain: feedstock preparation, anaerobic digestion, gas pretreatment, upgrading, compression, and downstream use.
Feedstock Handling
Food waste, agri waste, manure, straw, press mud, and organic MSW are prepared for processing.
Anaerobic Digestion
Engineered digesters convert biodegradable feedstocks into raw biogas and digestate.
Gas Pretreatment
Moisture, particles, sulphur compounds, and other impurities are managed before upgrading.
Upgrading
Membrane and PSA/VPSA systems enrich methane and reduce carbon dioxide content.
Compression & Use
Biomethane is compressed for fuel use, bottling, filling, heating, power, or similar end uses.
Why Choose a CBG Plant
BIOPOWER’s public positioning supports a strong waste, fuel, and environmental value proposition without overclaiming beyond the published technical data.
Waste-to-Fuel Conversion
Convert organic waste streams into a methane-rich renewable fuel instead of treating them as disposal only.
Transport Fuel Pathway
The site explicitly positions upgraded biomethane as suitable for vehicle-fuel applications.
Industrial Energy Use
CBG can also support heating and other industrial fuel-substitution opportunities.
Modular Scalability
Published upgrader packages and plant architecture support staged growth and project-specific sizing.
Lower Environmental Impact
Public benefit language across the site includes methane-emission reduction and cleaner energy pathways.
Approval-Oriented Development
Feasibility, DPR, compliance support, and SATAT/MNRE-linked project assistance are part of the offering.

What the Plant Can Include
The reviewed pages support this equipment and subsystem layer without adding assumptions that are not public.
| Subsystem | Website-Ready Description |
|---|---|
| Feedstock intake & handling | Collection, receiving, contaminant removal, pumping, auger feeding, silage storage, and similar feed preparation steps depending on feedstock type. |
| Anaerobic digestion | Feedstock-flexible digestion designed for process stability, availability, and conversion. |
| Gas pretreatment | Removal or management of moisture, particles, sulphur compounds, and related impurities before upgrading. |
| Membrane upgrading | Compact modular purification approach with no additional chemical or operating media and no heat requirement stated on the reviewed page. |
| PSA / VPSA upgrading | Pressure-swing gas purification with automatic purity control and skid-mounted system positioning. |
| Compression | Low-pressure compression up to 45 bar and high-pressure bottling / filling applications up to 250 bar. |
| Automation & monitoring | Publicly positioned as automatic, easily monitored, remotely controlled, and suitable for lower operating complexity. |
| Digestate handling | The digestion process also generates slurry or digestate as a reusable byproduct stream. |
Feedstocks & End-Use Applications
The BIOPOWER CBG pages support both a wide feedstock range and multiple downstream use pathways.
Frequently Asked Questions
These answers stay aligned with the publicly reviewed BIOPOWER CBG and related technical pages.
What is a compressed biogas plant?
It is a waste-to-fuel system that converts organic feedstocks into biogas through anaerobic digestion, then upgrades and compresses that gas into a methane-rich renewable fuel stream.
What feedstocks can be used?
The reviewed pages reference food waste, agri waste, straw and paddy straw, manure, press mud, and the organic fraction of municipal solid waste.
What upgrading technologies does BIOPOWER mention?
The public CBG content highlights membrane and PSA / VPSA-based upgrading systems.
How pure can the upgraded gas become?
BIOPOWER publicly states that upgraded gas can reach over 99% methane content.
What compression ranges are publicly mentioned?
The site states low-pressure compression up to 45 bar and high-pressure bottling or filling applications up to 250 bar.
Does BIOPOWER support feasibility and compliance documentation?
Yes. The public SATAT / MNRE page supports feasibility studies, DPR preparation, capacity planning, technology selection, feedstock planning, and regulatory-support positioning.
