Our Alcohol-to-Jet (ATJ) technology is the first proven global technology solution for SAF from ethanol.
Capable of using low-carbon and sustainable ethanol, our first-to-market technology has the supply-volume necessary to enable a scaled SAF industry. The LanzaJet® ATJ technology, combined with a deeply experienced team, will make sustainable fuel a reality worldwide.
Why LanzaJet SAF?
The fuels we produce stack up to rigorous jet and diesel standards — and go beyond sustainability. Independently certified for their benefits to the environment, our fuels significantly reduce greenhouse gas emissions and qualify for renewable fuel credits.
Our fuel can take any source of low-carbon ethanol – from ag waste, municipal solid waste, to carbon emissions, and more – enabling global production that leverages local, sustainable supply sources.
Our process can operate in maximum jet or diesel modes. That flexibility lets us meet varying production and market demands for these two high-value products.
Low-carbon ethanol is a sustainable fuel that can be widely and locally sourced from raw materials accessible around the world.
Our SAF significantly reduces greenhouse gas emissions and can be carbon-negative, depending on the source of ethanol used. It also cuts down contrail formation, sulfur emissions, and particulate matter by up to 95%.
90% of the hydrocarbons produced are in jet fuel range in max jet mode.
98% of the carbon available in the ethanol we use is converted to high value hydrocarbon products
Our SAF has a higher energy density than traditional Jet‑A fuel, making it a better quality fuel.
We convert ethanol to Synthetic Paraffinic Kerosene using a continuous catalytic process — a proven and approved pathway.
Approval to blend up to 50% LanzaJet SAF with conventional Jet A aviation fuel means that our decarbonization goal is within reach. Work is underway to allow for approval of up to 100% LanzaJet SAF. Low-carbon ethanol is a widely available starting point for our fuel production process. With raw materials readily available and accessible around the world, our technology can use any source of low-carbon ethanol, adhering to strict sustainability criteria.
Introducing CirculAir
Revolutionary and Commercially Ready Solution, Converting Nearly All Non-Oil Derived Waste Carbon Streams into SAF
CirculAir is an end-to-end solution from LanzaJet and LanzaTech, representing the most diverse feedstock platform available on the global SAF market.
It is an add on to LanzaJet’s two other pathways leveraged for its ethanol production.
Bio-Fermentation to Ethanol: Waste sugars are processed through fermentation to produce bioethanol, which is then converted into SAF.
Pyrolysis to Ethanol: Woody biomass waste is put through a Fast Pyrolysis process, breaking it down into sugar and biochar. The sugar is fermented into bioethanol, which is subsequently upgraded to SAF. The biochar is embedded in the soil as a long-term carbon sequestration solution.
Gas Fermentation to Ethanol (CirculAir): CirculAir can take nearly all non-oil based waste carbon streams, such as municipal solid waste (MSW), agricultural residues, woody biomass, or even industrial off-gases and direct air capture. These feedstocks are treated into a syngas, which are then put through LanzaTech’s gas fermentation technology in order to be upgraded into ethanol. The ethanol is then upgraded to SAF through LanzaJet’s ATJ technology process.
CirculAir is a drop-in sustainable fuels solution, tested and de-risked for large-scale deployment. With its ability to re-purpose both biogenic (solid waste streams) and synthetic (gaseous waste streams) sources of carbon, it in turn enables the ATJ pathway to deliver a combination of Biofuel and Power-to-Liquid outputs for the global SAF ramp-up.
