Honeywell and GranBio are collaborating to produce sustainable aviation fuel (SAF) using their respective technologies. The production of SAF is considered essential for decarbonizing the aviation industry, which accounts for a significant portion of global greenhouse gas emissions. Governments are increasingly mandating greater SAF usage to meet decarbonization goals. The EU, for example, has mandated minimum SAF usage, increasing to 70% of fuel blends by 2050.
GranBio’s cellulosic ethanol “AVAP” technology converts biomass, including forest and agricultural residues, into sugars, lignin, and nanocellulose. Honeywell’s ethanol to jet (ETJ) technology can then convert these cellulosic sugars into SAF. The process benefits from abundant and low-cost feedstocks and has the potential to revitalize rural manufacturing and forestry value chains.
The SAF produced in this collaboration will be manufactured at GranBio’s upcoming U.S. demonstration plant, with support from an $80 million grant from the U.S. Department of Energy. The plant will produce approximately 2 million gallons of SAF annually.
This initiative highlights the growing importance of SAF in the aviation sector’s efforts to reduce its carbon footprint and align with global decarbonization targets.
, an independent military force, and allied militias in Sudan raped several dozen women and girls in West Darfur’s capital, El Geneina, and those fleeing to Chad between late April and late June 2023, Human Rights Watch said today. The assailants appear to have targeted people because of their Massalit ethnicity and, in some cases, because they were known activists.){kind=link}
