Stop managing waste. Start creating value
Custom made biogas upgrading solutions
Don't just settle for clean gas. Demand more. Our patented, zero-waste technology transforms your entire gas stream into valuable assets, delivering a lower TCO and a higher return.
Engineered for value, not for waste
Most biogas upgrading systems trade one problem for another: your gas is clean, but you're left with a costly, hazardous waste stream. At Gazpack, we believe this is a fundamental engineering flaw.
Born from the uncompromising demands of the offshore industry, our patented systems are built on a single principle: waste does not exist. We don't just sell a standard product; we engineer a custom solution that converts every component of your gas stream into a valuable, safe, or reusable asset.
The result is more than just clean gas. It's a smarter investment, delivering a fundamentally lower total cost of ownership. It's a smarter design, offering radical operational simplicity within a compact, space-saving footprint. And it's a smarter partnership, providing the peace of mind that comes from a truly circular solution, tailor-engineered in-house to meet your exact needs.

Sulago, the smart solution for small to mid-scale facilities
Specifically engineered for capacities from 20 to 1500 Nm³/h, the Sulago® system eliminates H₂S by employing our patented SULAFER® technology. It replaces outdated, wasteful methods with a clean process that produces a harmless, solid by-product instead of costly chemical waste. Optional add-on: our CO₂ removal module upgrades the gas to biomethane. Together they form SULAGO+.
- No more hazardous wasteReplaces active carbon with a harmless, easy-to-handle solid
- Slash operational costsOur SULAFER® has 10x the capacity, drastically cutting replacement fees
- Set-and-forget operationScheduled to meet production timelines
SULAWAY® system
Sulaway for maximum value in large-scale operations
Originally designed for the demanding oil & gas industry, the Sulaway® system is engineered for volumes of 1500 Nm³/h and higher. It transforms the challenge of high H₂S levels into a new revenue stream by converting waste gas into valuable sulfuric acid. Optional add-on: our CO₂ removal module upgrades the gas to biomethane. Together they form SULAWAY+.
- Turn waste into revenueTransforms your H₂S waste stream into a sellable, high-grade asset
- Just 2 days maintenanceAverages only two days of scheduled downtime per year
- Offshore-grade durabilityEngineered with our offshore DNA for unmatched, long-term reliability
COt(w)oGO system
COt(w)oGO, for when only the CO₂ has to go
For plants that already have H₂S under control, COt(w)oGO removes the CO₂ with membranes and upgrades biogas to biomethane for the grid, Bio-CNG or Bio-LNG. Combined with Sulago or Sulaway, it turns them into SULAGO+ and SULAWAY+.
- Keep your methaneSurplus gas is recycled, keeping methane slip below 0.5%
- No chemicals, no wasteSeparation by membranes alone
- Your CO₂, your productLiquefy it with COt(w)oGO(L) for storage or reuse
We see value where others see waste
Raw biogas contains more than just methane. It holds energy (RNG), valuable resources (CO₂), and harmful contaminants (H₂S). Where standard systems focus only on the energy and leave you to deal with the rest, our philosophy is different. We believe in total value conversion. Our integrated systems are engineered to capture and transform every component into a usable, sellable, or reusable product. No waste, no compromise. Just engineered value.
Unmatched expertise
Born from the offshore industry, our systems are engineered for extreme reliability and a 20+ year lifespan. We build to last.
Zero waste philosophy
Our patented technology creates value, not waste. We convert contaminants into harmless or sellable by-products, eliminating your disposal costs.
Radical low maintenance
Our Sulaway® system averages just two days of maintenance per year. That means higher availability and a healthier bottom line for your business.
Tailor-engineered for you
Your challenge is unique. Your solution should be too. We design and build your system in-house to match your exact operational and financial goals.
Our Engineering Philosophy
Built to a higher standard
These are traditional, basic absorption methods that come with significant hidden costs. Our patented SULAFER® technology is fundamentally smarter:
- It transforms H₂S into a harmless solid, instead of creating hazardous (carbon) or disposable (steel) waste.
- It has up to 10x the capacity, drastically reducing replacement cycles and slashing your operational costs.
- It's a safer, cleaner process that eliminates the risks and fees associated with waste disposal.
Biological scrubbers are a good, chemical-free alternative, but they trade chemicals for complexity. Our engineered systems offer a more robust and predictable solution:
- Extreme reliability: Our mechanical process is insensitive to the biological fluctuations that can cause downtime in other systems. It's built on our offshore DNA: it simply works, 24/7.
- Compact footprint: Our systems are significantly more compact, saving valuable space and simplifying integration into your plant.
- Simple operation: You manage a machine, not a living organism. Our fully automated systems require no expert biological knowledge to run flawlessly.
Our systems are fully automated and designed for extreme reliability, a principle inherited from our parent company Airpack's demanding offshore experience.
- "Set-and-forget" operation with robust PLC control.
- Handles gas fluctuations automatically and safely.
- Frees up your team to focus on core operational tasks.
Our entire philosophy is to eliminate the hidden costs that plague standard systems. Your TCO is fundamentally lower for three clear reasons:
- Zero waste disposal costs: We create value or harmless by-products, not costly waste.
- Radically lower maintenance: More uptime means higher production and a healthier bottom line.
- Fewer consumables: Our high-capacity processes mean more predictable and lower operational expenses.
