Publication Open Access Environmental impact analysis of natural cork stopper manufacturing(MDPI, 2022) Flor Montalvo, Francisco Javier; Martínez Cámara, Eduardo; García Alcaraz, Jorge Luis; Jiménez Macías, Emilio; Latorre Biel, Juan Ignacio; Blanco Fernández, Julio; Ingeniería Mecánica, Energética y de Materiales; Mekanika, Energetika eta Materialen IngeniaritzaFor both wine makers and customers, natural cork stoppers are a symbol of quality. More-over, they are essential for maintaining the organoleptic properties of bottled wines throughout their lifespan. This research relied on the life-cycle assessment (LCA) methodology to analyze the relationship between the efficient usage of cork planks and the environmental impact of the cork stopper manufacturing industry. The goals of this research were to analyze and determine the environmental impact of producing 1 kg of natural cork stoppers. The analysis considered cork stoppers of two sizes—24 × 44 mm and 26 × 44 mm—and two manufacturing methods—punching and turning. Our findings indicated that the 24 × 44 mm cork stoppers produced with the punching method had a slightly lower environmental impact (1.36 kg CO2 eq/kg) across the ten analyzed impact categories. Conversely, 26 × 44 mm turned corks had the highest impact on the environment (1.49 kg CO2 eq/kg). Additionally, a comparison of same-sized punched and turned cork stoppers showed that the former had a lower environmental impact. This phenomenon is directly related to plank usage. In conclusion, there is a clear relationship between environmental impact and the efficient usage of raw material. In turn, an efficient usage of raw material depends on both the manufacturing method and stopper size.Publication Open Access Water footprint of a 5 kg bag of washed potatoes(Cal-Tek srl, 2023) Sáenz Baños, Mercedes Irache; Latorre Biel, Juan Ignacio; Martínez Cámara, Eduardo; Jiménez Macías, Emilio; Blanco Fernández, Julio; Ingeniería; IngeniaritzaClimate change and water scarcity increasingly impact agricultural systems. Therefore, studying food systems in depth through a water footprint perspective and their effects on water resources is necessary. Potatoes are one of the most widely consumed foods globally. This article analyzes the water footprint of a 5 kg bag of washed potatoes using a life cycle assessment (LCA) methodology. A cradle-to-gate model is created, and four environmental impact assessment methods are applied to determine the impacts on water resources. The results obtained are consistent across all four methods, indicating that water consumption in the potato washing stage has the most significant impact. The second highest water consumption occurs during the agricultural cultivation phase. Furthermore, this agricultural phase has the highest impact on other water-related categories, including such as Water Pollutants, Persistent Organic Pollutant (POP) into Water, Heavy Metals into Water, and Radioactive Substances into Water.
