摘要

Conventional oil recovery relies on hazardous solvents and high-energy processes, which is why the demand for sustainable, eco-friendly oil extraction methods is increasing. One such method is safe aqueous extraction of natural oleosomes. However, even oleosome recovery methods often involve resource-intensive extraction and purification steps, and quantitative evaluations of their sustainability using green metrics are seldom reported. In this work, we evaluate the sustainability of aqueous extraction of oleosomes from buriti (Mauritia flexuosa L.f.), an oleaginous Amazonian fruit rich in bioactive lipids, by utilizing three green metrics tools: Eco-Scale, Path2Green, and AGREE. These metrics assess reagent hazard level, energy demand, waste generation, and overall process greenness. The Study 1 achieved an Eco-Scale score of 89 (“excellent”), a Path2Green score of 0.019, and an AGREE score of 0.63, exceeding the scores of all other oleosome extraction methods that were assessed. Higher scores are associated with the use of non-hazardous reagents, lower energy demand, and the avoidance of extensive purification while maintaining high oleosome yield. Overall, this work provides a green metrics-based reference for the oleosome aqueous recovery methods under study in this work, with particular focus on buriti oleosome extraction, and illustrates how combined green metrics can support circular and lower-impact processing routes, facilitating the development of new, eco-friendly extraction methods and technologies.
