A Korean pilot plant converting landfill methane into sustainable aviation fuel demonstrates a scalable, circular pathway with global implications for net-zero flight
A pilot-scale facility in South Korea has achieved what until recently remained largely theoretical: the daily production of sustainable aviation fuel (SAF) directly from landfill gas. Delivering approximately 100 kilograms of SAF per day, the project validates a decentralised, waste-based fuel pathway that could materially alter the global aviation decarbonization equation.
Led by the Korea Research Institute of Chemical Technology (KRICT) in partnership with EN2CORE Technology, the initiative converts methane-rich landfill emissions into liquid jet fuel-transforming one of the most harmful greenhouse gases into a strategic energy resource.
For aviation leaders facing mounting pressure to decarbonize without compromising growth, this development signals more than technical progress. It points to a new supply model for SAF-distributed, circular, and potentially global in scale.
Why This Matters: SAF Supply Is the Aviation Bottleneck
Sustainable aviation fuel is widely acknowledged as the single most critical lever for reducing aviation emissions this decade. Yet production remains constrained by high costs and limited feedstocks, particularly the industry’s heavy reliance on used cooking oil under current HEFA pathways.
According to IATA, the aviation sector will require ~500 million tonnes of SAF annually by 2050 to reach net-zero emissions. By comparison, global SAF output in 2025 stood at roughly 2 million tonnes-less than 1% of demand.
The Korean pilot directly addresses this imbalance by unlocking landfill gas-a low-cost, globally abundant feedstock generated from food waste, agricultural residues, and organic municipal waste.
Turning Methane into Jet Fuel: How the System Works
The Korean team developed an end-to-end integrated process, converting landfill methane into aviation-grade hydrocarbons through the following steps:
- Gas purification and CO₂ reduction using membrane separation
- Plasma reforming to convert methane into synthesis gas (CO + H₂)
- Fischer–Tropsch synthesis, producing liquid hydrocarbons suitable for jet fuel
Crucially, advanced cobalt- and zeolite-based catalysts were engineered to increase selectivity toward liquid fuels, minimizing waxy by-products and improving overall efficiency.
The Microreactor Advantage: Scaling Through Modularity
At the heart of the breakthrough is a miniaturised microchannel reactor, designed to rapidly dissipate heat and protect catalyst integrity-one of the historical barriers to scaling gas-to-liquid processes.
Key advantages include:
- Reactor volume reduced to one-tenth of conventional systems
- Modular design, allowing capacity to scale by adding units
- Stable operation under continuous conditions
The entire pilot facility occupies ~100 square metres, demonstrating that SAF production need not rely exclusively on large, centralized refineries.
For executives, this introduces a compelling new concept: distributed SAF production at or near waste sites, reducing logistics costs while expanding global supply.
Global Impact: A Circular Model with System-Level Benefits
The implications extend far beyond South Korea.
Methane is a high-impact greenhouse gas, with landfills representing a major source globally. Converting landfill emissions into SAF offers a dual climate benefit:
- Eliminating methane releases from waste sites
- Displacing fossil jet fuel in aviation
If replicated internationally, decentralised landfill-based SAF plants could:
- Diversify SAF feedstocks at scale
- Reduce reliance on constrained biomass supplies
- Accelerate SAF deployment in regions lacking large refineries
- Strengthen national energy security through local production
This aligns directly with circular-economy principles, turning urban waste streams into strategic aviation energy assets.

The Executive Takeaway
While still at pilot scale, Korea’s landfill-to-SAF facility represents a credible proof point, not a lab experiment. It demonstrates that waste-derived, modular SAF production is technically viable, spatially efficient, and potentially scalable.
For airline CEOs, fuel strategists, policymakers, and infrastructure investors, the signal is clear:
the future SAF market will not be built on a single pathway.
Decentralised, waste-based fuel systems could become a critical pillar alongside synthetic e-fuels and bio-based SAF-especially as the industry races to close a widening supply gap.
Turning rubbish into jet fuel is no longer a metaphor. It is an emerging business model-one that could materially shape aviation’s path to net zero.
