摘要: To date limited work has focused on assessing the economic viability of scCO2 extraction to obtain waxes as part a biorefinery. This estimates costs for wax from maize stover. The cost manufacture (COM) stover was found be €88.89 per kg wax, with fixed capital investment (FCI) and utility (CUT) contributing significantly COM. However, this value is based solely does not take into account downstream processing biomass following extraction. extracting can reduced by utilizing pelletized leaves combusting residual generate electricity. would lead an overall €10.87 (based 27% combustion efficiency electricity generation) €4.56 43% generation). A sensitivity analysis study showed that (cost electricity) had greatest effect
