Environmental and Economic Assessment of a Laboratory-Scale Biocosmetics Production Process from Pomegranate Waste

Year: 2026

Type: article

Abstract: The transition towards a circular economy of agri-food wastes requires innovative strategies for transforming them into value-added products. This study evaluates the environmental and economic sustainability of a laboratory-scale process that converts 100 g of pomegranate waste, experimentally processed and defined as functional unit (FU), into a cosmetic emulsion. Primary data were collected from laboratory activities carried out in an Italian university, including material and reagent consumption, equipment operating times and energy use. A cradle-to-gate Life Cycle Assessment was performed in SimaPro according to ISO 14040 and 14044 using the Environmental Footprint 3.1 method, while Life Cycle Costing was developed in Microsoft Excel using the same system boundaries. The process valorized the three main pomegranate fractions (arils, mesocarp and exocarp) to obtain a cosmetic emulsion. The exocarp treatment was identified as the main impactful phase. The overall climate change impact reached 328 g CO2 eq/FU, while fossil resource use amounted to 5.3 MJ/FU. The total production cost was estimated at 189 €/FU, mainly due to labor, reagents, enzymes and equipment costs. Although laboratory-scale operation results in relatively high impacts and costs, the study identifies the main hotspots and provides a baseline for future process optimization and industrial scale-up.
