Identifying the sustainability route of asparagus co-product extraction: From waste to bioactive compounds

• Three biorefineries are modelled, focusing on the rutin extraction from asparagus waste. The environmentally compared with Life Cycle Assessment methodology. pressurized liquid-based scenario reports best environmental profile. Energy consumption is responsible for largest contributions to burdens. Sensitivity analysis performed considering different allocation and agents. Rutin a flavonol glycoside that found in greater proportion stalks. Considering possibility of valorization solid waste food industry, this research aims evaluate compare profile schemes extraction. Specifically, Soxhlet, liquid supercritical fluid extractions, all them using ethanol as extracting agent. conducted according methodology under mass economic allocation. results, allocation, show based have However, when considered, worst choice. Consequently, choice solvents will influence Soxhlet performance. In regard, ethanol, methanol ethyl acetate selected. solvent comparison identifies agent
