Honeywell and GranBio Technologies are joining forces to produce carbon-neutral sustainable aviation fuel (SAF) from biomass residues at a US-based demonstration plant scheduled for start-up in 2026.
The effort will see the combination of Honeywell’s ethanol-to-jet (ETJ) technology with GranBio’s cellulosic ethanol AVAP® technology that coverts biomass, including forest and agricultural resides, to pure low-cost, low-carbon intensity sugars, lignin, and nanocellulose.
Once produced, the cellulosic sugars are converted to both SAF, through Honeywell’s ETJ technology, and biochemicals, through a separate process.
Bernardo Gradin, CEO of GranBio, notes that, in addition to forest and agricultural residue available for feedstocks, there is also enormous potential to retrofit idle pulp and paper facilities in the US.
