Insights from combining techno-economic and life cycle assessment – a case study of polyphenol extraction from red wine pomace

To determine the environmental and economic performance of emerging processes for valorization red wine pomace, a techno-economic assessment (TEA) Life Cycle Assessment (LCA) are combined at an early design stage. A case study two polyphenol extraction methods laboratory scale, solvent (SE) pressurized liquid (PLE), were first analyzed via carbon footprint (CFP). Subsequently, scale was improved translated into industrial TEA performed on designs. Finally, LCA applied again with all impact indicators information gathered from both concise decision support, using Multiple Criteria Decision Analysis (MCDA). SE performs better than PLE, due to lower DW ratio less expensive processing setup in terms. The CFP aided showing potential hotspots highlighted need reduce use. MCDA showed shift support depending how strongly or benefits valued eases interpretation 19 different derived TEA-LCA results. Both PLE dry weight (DW) 5 10, respectively, perform competitively while 10 outperforms 25. illustrated calculations (CFP), may be improve process design.
