Landfill gas upgrading

Custom-made landfill gas upgrading systems

Tailored solutions for high-H₂S, high-CO₂ landfill gas streams — designed for maximum recovery and minimal emissions.

Turn landfill gas into lasting value

Landfill gas recovery installations face a unique set of challenges: aging gas fields, variable gas composition, high sulfur loads, and pressure to reduce methane emissions. On top of that, operators often struggle with underperforming gas upgrading systems that require frequent maintenance, flare excessive volumes of gas, or fail to meet current RNG standards.

At Gazpack, we understand these realities because we've been building and delivering tailor-made gas upgrading systems since 2006. Our solutions are engineered to handle exactly the kind of volatile, high-contaminant gas that comes from landfills — and turn it into a clean, valuable resource. From initial design to final installation, we manufacture complete systems that are robust, modular, and designed to last in tough environments.

We support certification and compliance processes by integrating the right purification steps and ensuring the final output meets grid injection or fuel use standards. More importantly, we act as a manufacturing partner — not just an engineering firm. That means we stay hands-on during production, testing, and delivery, with systems tailored to your volume, footprint, and regional compliance needs.

Whether you're converting landfill gas to RNG, boosting performance of an older installation, or scaling to meet new regulations, Gazpack helps you get more value out of every cubic meter.
