Brazilian CBP - Technoeconomic analysis data
Description
This data is related to the paper entitled "Techno-economic analysis of sugarcane bagasse and straw conversion into cellulosic ethanol via consolidated bioprocessing". That features the evaluation of sugarcane bagasse and straw conversion to ethanol at stand-alone facilities generating electricity from residues. The following scenarios were evaluated: Conventional, featuring hydrothermal pretreatment, fungal cellulase, and yeast fermentation (current commercial standard); Mid-term consolidated bioprocessing (CBP), relying on bagasse solubilization without pretreatment or cotreatment; and Mature CBP, incorporating cotreatment but no pretreatment and considering significant technological advance of the CBP. Available here are the spreadsheets used for Material and Energy balance calculation, Capital and Operational costs estimation and Cash flow analysis. Also available are the description and python code used for Monte Carlo analysis of the ethanol and capital investment variations. This data can be used as a source to implement other techno-economic analysis in the biorefinary context.

Steps to reproduce
Material and energy data were extracted from an Aspen Plus (V10) simulation. Capital cost (CapEx) estimations were based on Humbird et al. (2011) report for lignocellulose ethanol production spreadsheets, costs were adjusted considering 2023 CEPCI. And Operational costs estimations were based on the data from Junqueira et al. (2017) and adjusted considering the Brazilian inflation rate (IPCA) of 2023. Uncertainty analysis for the ethanol and CapEx were evaluated calculating the probability of achieving a positive NPV. Python was used to model the Monte Carlo analysis and description was sourced with the respective code.
