Logistics and Costs of Agricultural Residues for Cellulosic Ethanol Production

There is global pressure to make advanced biofuels profitable. For cellulosic ethanol, three aspects remain as bottlenecks: collection of feedstocks, pretreatment methods, and enzyme production. In this paper, the first aspect investigated, by addressing main challenges for logistics agricultural residues. A logistic supply chain corn stover utilization ethanol production in Mexico proposed, a cost structure designed its estimation. By applying value methodology, seven links set minimum selling prices (MSPs) residues were determined. Furthermore, harvest index (HI), crop residue (CRI), nutrient substitution extraction residues, costs also calculated case study. The results HI 0.45, CRI 1.21, potential 7 kg N, 2.2 P2O5, 12.2 K2O per ton stover. estimated MSPs was: $28.49 USD/ton (for delivery biorefinery’s gate), $31.15 storage), $48.14 delivery, storage, replenishment). Given impact feedstock on profitability knowing details logistical information critical advancing field Mexico. We found that only 20% farmers currently sell their residues; however, 65% would be willing do so, significant percentage
