This study designs and evaluates the economics and spatial configuration of a supply chain for sustainable aviation fuel from hybrid poplar in the southeast US region. Mixed integer linear programming is used to satisfy a hypothetical demand of 120 Mgal year~(-1) for two production systems, one using conventional preprocessing technology (the hammermill system) and the other using a newly introduced technology (the rotary shear system). The economic impact of these preprocessing technologies is evaluated across all supply chain stages, as well as the vehicle mileage traveled. Results suggest that the rotary shear system presents some economic advantages over the hammermill system. Compared to the traditional system, the rotary shear system decreases preprocessing costs by 6.4%, reactor-ready biomass costs by 15.2%, and sustainable aviation fuel production costs by 7.9%. The rotary shear system also requires 25.2% less planted area of hybrid poplar than the hammermill system, thus reducing the vehicle mileage traveled along the supply chain, which has positive implications for emissions and vehicle risk exposure.
