However, currently, the study of macroalgal biorefineries is less developed than their terrestrial biomass-based counterparts. In this regard, the validation of this concept is crucial, considering not only technical feasibility but also including issues related to the environmental dimension of sustainability. Therefore, this work proposes the environmental impact assessment using a life cycle assessment (LCA) of an integrated biorefinery based on macroalgae, employing an open-access computational tool, OpenLCA. The production of 600 t/yr of dimethyl isosorbide (DMI) is considered and compared to the possibility of alternatively producing 322 t/a of DMI and 244 t/a of alginate, equivalent to the use of 1864 t/yr of Patagonian macroalgae. Producing sodium alginate jointly with DMI significatively reduces the environmental impact among all categories. For instance, if it is considered “climate change”, the impact within this category is reduced 25,8 % when both compounds are produced. El empleo de biomasa de algas marinas macroscópicas bajo el concepto de biorrefinería se presenta como una de las alternativas más prometedoras a la hora de obtener una amplia gama de compuestos mediante la valorización de la biomasa. Sin embargo, en la actualidad, el estudio de biorrefinerías macroalgales se encuentra menos desarrollado que el de sus análogas basadas en biomasa terrestre. En este sentido, resulta clave la validación de este concepto mediante una perspectiva que no solo incluya la factibilidad técnica, sino también cuestiones asociadas a la dimensión ambiental de la sostenibilidad. En virtud de esto, en este trabajo, se propone la evaluación de impacto ambiental mediante análisis de ciclo de vida (LCA, por sus siglas en inglés) de una biorrefinería integrada basada en macroalgas patagónicas utilizando una herramienta computacional de acceso libre, OpenLCA. Se considera la producción de 600 t/a de dimetil-isosorbida (DMI) y se compara con la posibilidad de producir alternativamente 322 t/a de DMI y 244 t/a de alginato, equivalente al uso de 1864 t/a de macroalga patagónica. Producir alginato de sodio juntamente con DMI reduce significativamente el impacto ambiental del proceso en la mayoría de las categorías de impacto analizadas. Por ejemplo, si se toma la categoría de “cambio climático”, el producir ambos compuestos se reduce un 25,8 % el impacto.
