Table 5 Description of modeled scenarios for the estimation of environmental and cost impacts for a cellulosic ethanol production system using dilute-acid pretreatment

From: Maize feedstocks with improved digestibility reduce the costs and environmental impacts of biomass pretreatment and saccharification

Scenario Description
I (benchmark scenario) Pretreatment severity: high
Maize feedstock class: “excellent” cell wall digestibility
Based on TGP performance (3.5 t ha−1) of genotype LG210P106790
II Pretreatment severity: high
Maize feedstock class: “poor” cell wall digestibility
Based on the average TGP performance (3.2 t ha−1) of de “poor digestibility” cultivar class
III Pretreatment severity: low-mid
Maize feedstock class: “excellent” cell wall digestibility
Based on TGP performance (2.9 t ha−1) of genotype LG210P106790
IV Pretreatment severity: low-mid
Maize feedstock class: hypothetical scenario
Based on TGP performance (~3.7 t ha−1) of a hypothetical forage maize cultivar combining the best characteristics available in the entry panel (i.e., highest concentration of stem soluble glucose, holocellulose content, enzymatic convertibility, and biomass yields)
