Custom made biogas upgrading for biogas operators
Tailor-built systems for stable output, low emissions, and full valorization - even at high H₂S and CO₂ levels. Built to match your grid, heat, and CO₂ recovery targets.
Biogas upgrading systems that match your specs - and your operations
Whether you run a composting facility, anaerobic digester, co-digestion installation, or WtE plant – your gas quality is never constant. You deal with fluctuating methane levels, variable sulfur content, and sometimes poor calorific values that make injection or downstream use difficult. Add to that stricter compliance demands and volatile energy markets, and it’s clear that simply flaring is no longer the answer.
At Gazpack, we design, build, and deliver custom-built biogas upgrading systems tailored to your specific input gas and desired output – whether that’s grid injection, heat use, or CO₂ reuse. Since 2006, we’ve worked closely with operators across Europe and beyond to manufacture full systems that remove H₂S and CO₂ in a single integrated process, reduce OPEX, and open new revenue streams through RNG or carbon valorization.
We don’t just engineer ideas – we manufacture and deliver fully built, tested systems. Our units are plug-and-play, scalable, and tailored to your gas stream and compliance needs. Whether your challenge is meeting local specs, capturing value from waste gas, or reducing maintenance downtime, we build to solve it.
Our team also supports certification processes where needed – helping you meet regional grid or safety standards without overengineering or overspending. All systems are manufactured in-house, designed for long-term durability, and built for easy operation, with minimal methane slip and low environmental impact.

Industry solutions we support
-
Composting Facilities Remove H₂S and CO₂ from low-yield gas streams to enable cleaner burning or compliance. Turn a formerly wasted byproduct into an energy-positive asset.
-
Anaerobic Digesters Upgrade variable biogas into RNG, heat, or clean CO₂ - even with frequent feedstock changes. Enable compliance, capture value, and lower plant emissions.
-
Co-Digestion Installations Match output quality to grid or end-use specs, even with multiple feedstocks. Simplify gas treatment with an integrated system, from raw gas to final spec.
-
Waste-to-Energy (WtE) Plants Avoid flaring and reduce odor emissions with full gas polishing. Tap into new revenue through energy recovery or CO₂ reuse.
