Abstract
Este estudio aborda una evaluación del impacto ambiental asociado con el proceso productivo de azúcar blanco de remolacha en la planta IANSA Ñuble, Chile, siguiendo la metodología de Análisis de Ciclo de Vida (ACV) conforme a la norma ISO 14.044. Se cuantificó las emisiones de Gases de Efecto Invernadero (GEI), a lo largo de las etapas productivas, desde el cultivo hasta la distribución final del producto en la temporada 2023. La huella de carbono total del proceso productivo es 1,617 kg CO2-eq kg-1 de azúcar blanco, de los cuales un 73% provienen del proceso en fábrica y un 19% de la producción de remolacha. Mediante la caracterización de las principales fuentes de GEI, se determinó que los de mayor relevancia son: consumo de carbón con un 90,3% de la huella en fábrica, y el uso de fertilizantes nitrogenados con un 37,3% en el cultivo, concluyendo así, que la implementación de prácticas más sostenibles, cómo la sustitución del carbón por otras fuentes energéticas como biomasa, resulta en reducciones significativas de la huella de carbono.
This study addresses an environmental impact assessment associated with the production process of white beet sugar at the IANSA-Ñuble plant in Chile, following the life cycle analysis (LCA) methodology in accordance with ISO 14,044. Focusing on the 2023 beet season, greenhouse gas (GHG) emissions are quantified throughout all production stages, from cultivation to final distribution of the product. The total carbon footprint of the entire white sugar production process is 1.617 kg of CO2 equivalent per kilogram of white sugar, of which 73% comes from the factory process and another 19% from beet production. By identifying and quantifying the main sources of GHGs, coal consumption, which represents 90.3% of the factory footprint, and the use of nitrogen-based fertilizers, which represents another 37.3% of the crop, were identified as critical points. Accordingly concluding that the implementation of more sustainable practices, such as replacing coal with other energy sources such as biomass, results in significant reductions in the carbon footprint.
