Biogas Industry
Upgrade raw biogas to biomethane with high methane recovery, low operating cost, and saleable food-grade CO₂. Modular units for grid, CNG, LNG, or onsite use.
How It Works
Step-by-step
From raw biogas at the digester to saleable biomethane and monetized CO₂. Each stage is designed to protect uptime, meet spec, and unlock extra value.
Tie-in and stabilize the feed
We connect at the digester or landfill header, stabilize flow and pressure, and route gas into the upgrading line with clear battery limits for utilities and safety.
Protect downstream equipment
Front-end conditioning removes H₂S, moisture, particulates, and siloxanes. This protects separation media, improves energy use per upgraded Nm³, and keeps purity stable during feed swings.
Separate CO₂ from CH₄ with high selectivity
High-efficiency separation maximizes methane recovery and produces a clean CO₂ stream. Closed-loop controls hold CH₄ purity to grid or vehicle-fuel specs while minimizing slip.
Store side streams safely and flexibly
CO₂ can be buffered to smooth operations, match offtaker schedules, and protect continuous plant uptime. Storage strategy is sized to site logistics and local demand.
Condition and liquefy for sale
Condition, dry, and liquefy CO₂ to food or industrial grade. This opens additional revenue channels and decouples production from immediate truck loading.
Move product where it pays best
Inject biomethane to grid or load to CNG/LNG. Schedule CO₂ truckloads directly from storage. Documentation and metering support billing, certificates, and compliance.

Yield impact
More biomethane from every Nm³
High-selectivity separation and robust polishing convert more raw biogas into sellable biomethane while keeping slip very low. Stable, on-spec output strengthens certificate revenue and reduces off-take penalties. The higher recovery improves energy sold per Nm³ of feed, supports stronger carbon-intensity scores under certification schemes, and makes production planning more predictable across seasonal feed changes.
A higher recovery rate also unlocks more value from side streams. Clean CO2 can be buffered or liquefied for sale, while flexible setpoints and ramp rates let you match output to grid, CNG or LNG demand. With tighter control during feed swings, you limit flaring, protect equipment health, and keep weekly and monthly yield closer to plan.

Benefits
Benefits of Galloxol® in Biogas Upgrading
Build a project that performs on paper and on the ground. These benefits focus on day-to-day reliability, compliant operations, and practical integration so your plant delivers predictable output and bankable revenue.
Secure supply and uptime
Design for resilience keeps the plant producing through feed swings and planned maintenance. Buffer vessels, smooth start sequences, and permissive operating windows help you stay on spec even when digester output varies through the day or across seasons. Operators get a stable biomethane stream that is easier to schedule and sell.
Redundant critical components and remote diagnostics shorten interventions. When something needs attention, alarms are actionable, parts are standardised, and procedures are clear, so downtime is measured in hours, not days.
Compliance made practical
Meeting gas grid, CNG or LNG specifications is only part of the job. Records, trend logs, and calibration trails matter for auditors and for internal governance. With built-in data capture and reporting hooks, you can show exactly how the plant held purity, dew point, and odorisation within limits.
Clear operating envelopes and interlocks help teams avoid off-spec production. Training materials and commissioning checklists support handover so that compliance is not just achieved at start-up but maintained through normal staffing changes.
Stronger Revenue Certainty
Predictable output improves the economics of certificates and offtake contracts. When methane recovery is consistent and slip is low, each delivered Nm³ carries the value you contracted for, which stabilises cash flow and reduces disputes.
Commercial flexibility helps you place product where it pays best. If grid pricing softens, CNG or LNG loading can absorb output. If storage fills, controls can throttle to a profitable level without sacrificing long-term health of the equipment.
Smooth Site Integration
Upgrading has to fit your site’s realities, not the other way around. We plan tie-ins to digesters, flare, and power units with clear battery limits, utility balances, and heat integration that actually reduces your OPEX. Layouts account for crane access, traffic flows, noise, zoning, and ATEX or equivalent hazardous areas. Odorization skids, metering, and grid interconnects are specified alongside drainage, condensate handling, and frost protection so civil and mechanical teams can build once and build right.
Controls and data live where your operators already work. SCADA tags, alarm philosophies, and permissives align with your standards, while vendor packages are harmonized into one cause-and-effect matrix. We phase construction to minimize downtime, provide P&IDs and cable schedules that match what is installed, and hand over with training, spares lists, and commissioning checklists. The result is an upgrade that plugs in cleanly, starts up smoothly, and remains maintainable for the long haul.

Frequently asked questions
Need more clarity?
Below you’ll find quick answers to the questions we hear most, from feed-gas limits to maintenance routines. Expand any item for details; if you don’t see your question, our engineers are one click away.
All frequently asked questionsWe can deliver biomethane that meets EU pipeline injection standards and/or vehicle fuel specifications, depending on your target market. Our polishing steps remove moisture, siloxanes, H₂S, ammonia and other traces to align with legal limits. After commissioning, we verify quality via gas chromatographs and independent lab testing to ensure you meet required purity, Wobbe index, and methane content.
By beginning with thorough gas analysis and feedstock assessment, we understand the variability in your raw biogas (organic composition, moisture, contaminant levels). The system is configured with flexible pretreatment stages and modular separation options that can adjust to these variations. Together with ongoing monitoring, you’ll get stable biomethane output even in changing conditions.
Payback periods generally range from 2 to 5 years, depending on biogas flow, local energy costs, and desired gas specifications. Operating costs are carefully managed via low maintenance design, durable components, and minimal chemical/solvent use in pretreatment or polishing. Savings also come from reduced waste management costs (less emissions, fewer backups) and from premium pricing of purified biomethane.
