Honeywell and Brazil’s GranBio Technologies are partnering to produce carbon neutral sustainable aviation fuel (SAF) from biomass residues at a planned demonstration plant in the U.S.

GranBio’s patented AVAP process converts biomass, including forest and agricultural residues, to pure low-cost, low-carbon-intensity sugars, lignin, and nanocellulose. The cellulosic sugars are converted to both SAF, through Honeywell’s ETJ technology, and biochemicals, through a separate process.

Using forest biomass-derived ethanol from the AVAP process, jet fuel produced from Honeywell’s ethanol to jet fuel process can reduce greenhouse gas (GHG) emissions to net zero on a total lifecycle basis, compared to petroleum-based jet fuel.

“The AVAP technology has great potential, depending on feedstock and plant configuration to allow carbon negative SAF with current life cycle analysis,” said Bernardo Gradin, GranBio CEO. “Plus, in addition to vast forest and agricultural residue available for feedstocks, there is an enormous potential to retrofit idle pulp and paper facilities in the U.S., revitalizing forestry value chains and rural manufacturing with great social, environmental, and economic impact.”

GranBio’s subsidiary AVAPCO was selected by the U.S. Department of Energy to receive an $80M grant to support the demonstration plant that will produce ~2 million gallons per year of SAF upon start-up in 2026.

Honeywell now offers solutions across a range of feedstocks to meet the rapidly growing demand for renewable fuels, including SAF. In addition to Honeywell UOP Ecofining™, Honeywell’s renewable fuels portfolio includes ethanol to jet technology and the recently announced Honeywell UOP eFining™, which converts green hydrogen and carbon dioxide into eFuels.
