Techno-economical study of biogas production improved by steam explosion pretreatment

- The economy of steam explosion pretreatment for biogas production was studied.
- Aspen plus and Aspen Process Economic Analyzer were used for the evaluation.
- Total energy efficiency of the process is calculated to 80%.
- Production cost of methane from wheat straw and paper tube was 0.36-0.48 €/m3.
- The production cost of methane decreased by 36% using the pretreatment.
