Technoeconomic and Environmental Assessment of Alternative Biorefineries for Bioenergy and Polyphenolic Production from Pomace Biomass

Pomace is generated during fruit processing and regarded as a highly polluting waste stream due to its high moisture content, biological instability, acidic properties. To facilitate pomace management, this study has applied the biorefinery concept develop systems that value extraction. regard, alternative scenarios for production of polyphenolic compounds bioenergy from apple were investigated using ASPEN Plus process modeling, simulation, analysis. Systems facilitating polyphenols via use green solvents (i.e. subcritical water in scenario (a) ethanol (b)), while also co-producing bioenergy, compared system produced only (c)). Comparisons profitabilities environmental performances achieved considerations net present values (NPVs) potential impacts (PEIs) all scenarios. The was able show constituted economically viable strategy, with NPV US$ 19.86 million, (b) (c) determined have NPVs − 88.12 million 4.05 respectively. Scenario poorest performance PEI 148 kPEI/h. Notably, although (PEI 0.21 kPEI/h) better than 47 kPEI/h), economic infeasibility indicated it will be impractical consider valorization strategy scaled-up system. This therefore proposed may constitute preferred provided technological innovations, i.e., energy sources gas filters, are explored reduce major existing challenge enhanced global warming greenhouse emissions. provides information regarding sustainability implication executing different management industry.
