48 / SEEDWORLD.COM JUNE 2026 We’re Not Taking Food Off The Plate WHENEVER SUSTAINABLE AVIATION fuel (SAF) enters the public conversation, one question tends to rise above others: Why are we using food for fuel? It’s an understandable concern. Agriculture feeds the world, and any proposal that appears to divert crops from that mission deserves scrutiny. But the real ity of sustainable aviation fuel is far more nuanced than the headline suggests. More Than a Food-for-Fuel Debate Commercial aviation faces a unique challenge. Aircraft require a highly specialized fuel that does far more than simply burn in an engine. Jet fuel also serves as a coolant, lubricant and hydraulic fluid, and it must perform reliably from desert heat to temperatures well below zero at 40,000 feet. Unlike cars or trucks, aircraft cannot switch easily to batteries or hydrogen in the near term, particularly for long-haul flights. That is why sustainable aviation fuel has emerged as one of the most practical pathways for reducing avia tion’s carbon footprint. The good news is that SAF is not tied to a single crop, a single region or even a single type of feedstock. Turning Waste Into Opportunity Yes, some current pathways use vegetable oils and other lipid-based materials. But the future of sustain able aviation fuel extends well beyond edible crops. Agricultural residues such as corn stover and wheat straw, forestry byproducts, municipal solid waste, dairy residues, used cooking oils and purpose-grown energy crops such as switchgrass and miscanthus are all part of the broader opportunity. In other words, this is increasingly a story about making better use of materials that are already avail able rather than taking food off the table. That distinction matters. For agriculture, SAF represents an opportunity to create additional value from residues and byproducts that have historically generated little return. For rural communities, it offers the potential for new processing facilities, jobs and investment. For researchers and seed companies, it opens the door to innovations in biomass quality, crop genetics and feedstock optimization. Why Seed Companies Belong in This Story The characteristics breeders focus on every day — yield stability, oil composition, residue quality and regional adaptation — directly influence the econom ics of fuel production. Better feedstocks lead to more efficient conversion and lower costs. “... framing SAF solely as ‘food or fuel’ misses the bigger picture.” BY STEVE CSONKA, Commercial Aviation Alternative Fuels Initiative Executive Director Important questions remain; SAF must become more affordable, supply chains must mature and public concerns about land use and food security must con tinue to be addressed transparently and thoughtfully. Those conversations are essential. But framing SAF solely as “food or fuel” misses the bigger picture. What is taking shape is a new market built on innovation, diversification and the ability to transform underutilized biological resources into high-value products. Aviation will continue to need liquid fuels for decades to come. The question is not whether we will pursue more sustainable alternatives. The question is whether agriculture will help lead the way.
