Feedstock Diversity and Supply Security

Current Feedstock Mix

The 2026 global SAF supply relies heavily on HEFA pathways using waste oils, used cooking oil, and animal fats, which represent approximately 70% of total production. These feedstocks offer immediate scalability and favorable economics but face quantity constraints and increasing competition from renewable diesel producers.

Second-generation feedstocks including agricultural residues, forestry waste, municipal solid waste, and purpose-grown energy crops account for approximately 20% of supply, primarily through Fischer-Tropsch and alcohol-to-jet pathways. These feedstocks offer greater scalability potential but require higher capital investment and more complex processing.

Synthetic pathways using captured carbon and renewable electricity represent under 1% of 2026 supply but attract significant investment and policy support due to their theoretical scalability beyond biomass constraints.

Feedstock Competition and Pricing

Feedstock availability and pricing have emerged as critical concerns in 2026, with used cooking oil prices tripling since 2021 due to competition among SAF, renewable diesel, and biodiesel producers. This has driven supplier diversification strategies and increased interest in novel feedstocks including algae, camelina, salicornia, and genetically modified oil crops.

Major SAF suppliers have established vertical integration strategies, securing long-term feedstock supply through farmer partnerships, waste oil collection networks, and forestry agreements. Neste, for example, sources feedstocks from over 70 countries and maintains strategic reserves to buffer against supply disruptions.

Certification and Quality Standards

ASTM Approval Pathways

All commercial SAF sold in 2026 meets ASTM D7566 specifications through one of eight approved production pathways: HEFA-SPK, FT-SPK, FT-SPK/A, AtJ-SPK, Co-processing, CHJ, HDCJ, and HC-HEFA-SPK. These fuels must be blended with conventional jet fuel (typically at 10-50% concentrations) and meet rigorous quality testing before delivery to aircraft.

Several additional pathways await ASTM approval in 2026, including direct sugar-to-hydrocarbons (DSHC) and additional alcohol-to-jet variants, which could expand feedstock options and reduce production costs.

Sustainability Certification

Most SAF suppliers maintain third-party sustainability certifications under schemes including RSB (Roundtable on Sustainable Biomaterials), ISCC (International Sustainability and Carbon Certification), and SCS Global Services. These certifications verify feedstock sourcing, lifecycle emissions calculations, and compliance with sustainability criteria including land use, water usage, and social impacts.

Airlines increasingly require robust sustainability certification to claim emissions reductions under CORSIA and corporate sustainability reporting frameworks, driving suppliers to maintain multiple certifications across their supply chains.

Market Outlook and Supply Projections

2026-2030 Capacity Additions

Announced SAF production projects total over 10 billion gallons of annual capacity by 2030, though industry analysts expect 6-7 billion gallons of actual production due to financing challenges, permitting delays, and feedstock constraints.
