Comparative life cycle assessment of corn stover conversion by decentralized biomass pyrolysis-electrocatalytic hydrogenation versus ethanol fermentation

Abstract

Quantification of environmental impacts through life cycle assessment is essential when evaluating bioenergy systems as potential replacements for fossil-based energy systems. Bioenergy systems employing localized fast pyrolysis combined with electrocatalytic...

Comparative Life Cycle Assessment and Technoeconomic Analysis of Biomass-Derived Shikimic Acid Production

“…The costs of transportation were added to the reported values of each feedstock. The average trucking distance was calculated, as depicted in Figure . Rectangular coordinates were assumed because plots of land and the orientation of roads are generally rectangular.…”

“…The average trucking distance was calculated, as depicted in Figure 5. 54 Rectangular coordinates were assumed because plots of land and the orientation of roads are generally rectangular. The refinery was assumed to occupy the center of a 2.01 × 2.01 km 2 area not designated for cultivation.…”

Carbon capture from corn stover ethanol production via mature consolidated bioprocessing enables large negative biorefinery GHG emissions and fossil fuel-competitive economics

“…Published assessments of GHG mitigation with biofuels have focused primarily on displaced fossil fuel emissions rather than CO 2 capture. 21,22 It has been suggested that in time the value of biomass energy systems for photosynthetic carbon removal may exceed that for energy supply. 23,24 Studies have recently begun to leverage carbon capture and storage (CCS) technologies to enable net negative life-cycle emissions for biofuel production.…”
