This study evaluated the environmental impact of malted, decorticated, and split yellow lentils, specifically Moroccan (ML) and Onano (OL) varieties, cultivated in Morocco and Italy, using a cradle-to-retailer Life Cycle Assessment (LCA) approach. An analysis through SimaPro 9.5.0.0 software and the Product Environmental Footprint method revealed carbon footprints of approximately 4.5 and 3.3 kg CO2e per kg for malted, dehulled, and split MLs and OLs, respectively, representing increases of 50% and 52% compared to their untreated dry seed counterparts. The Product Environmental Footprints also rose significantly, by 50% for MLs and 55% for OLs, reflecting the higher water and energy demands, as well as additional waste generation, associated with the malting process. This study emphasizes the importance of focusing mitigation efforts on improving the agricultural phase, particularly in land and water use efficiency. While supplemental irrigation can boost yields, especially in water-limited regions, it significantly increases the environmental footprint, underscoring a trade-off between yield gains and sustainability. Consequently, the optimal environmental strategy may not involve increasing irrigation, but rather developing drought-resistant lentil varieties, which could reduce the overall environmental impact. |
