NEXTCHEM TECH SAF TECHNOLOGYAnalyzing the consume base required to locally supply feedstock necessary to run a 60 kt/y of SAF plant: target vs current situation in EU and USA

Currently UCO and AF represent the readily available feedstocks for HEFA-SAF. Current EU collection rates for UCO and AF are 2.4 kg/capita and 6.0 kg/capita respectively, translating into 23.3 million people required to provide the necessary feedstock for a 60 kt/y SAF plant (80 kt/y of feedstock). USA shows a more advantageous UCO and AF collection rates: 7.9 kg/capita and 14.1 kg/capita respectively, translating into 7.90 million people required for a 60 kt/y SAF plant.
The ambitious targets set by the EU up to 2050 in terms of SAF consumption (4.2 Mt in 2030, 60.6 Mt in 2050) will require huge volumes of SAF, thus feedstock demand will drastically increase. To avoid huge imports from feedstock-reach areas of the world (Southeast Asia), an increase in collection rates is needed alongside new volumes of feedstock coming from categories that are currently too expensive and/or too dirty to be processed by conventional pretreatments.
With NXC proposal, a 10 million people area could feed a 60 kt/y SAF plant (80 kt/y of feedstock). As a reference, 60 kt/y SAF is enough to fulfill the 2050 SAF predicted consumption of an airport like Palermo or Bari. To achieve the required collection rate of 8 kg/capita, not only supply chains of UCO and AF need to expand but also a portion of “unconventional” feedstocks shall be added to the collection pool. As of today, NXC proprietary pretreatment is capable of processing feedstocks such as POME, Brown Grease, Sewage Sludges. Therefore, combining new supply chains for alternative feedstocks and pretreatment technologies capable of treating novel feedstocks will be possible to reduce the consumer base to a sustainable value within ambitious legislation as is the case in the EU.
