Abstract
Resumen: Este estudio evalúa la producción de carbonato de Litio (Li2CO3) en Bolivia, abordando su posición en la cadena de valor global, el impacto ambiental del proceso productivo y su viabilidad económica. Bolivia, a pesar de poseer las mayores reservas de Litio, enfrenta barreras significativas para integrarse en la cadena de valor, limitándose a exportar productos intermedios sin participar en etapas downstream, como la producción de baterías, lo que reduce su competitividad global. El análisis del proceso productivo reveló una huella hídrica de 556,37 m3 eq. mundo/t y una huella de carbono de 12,5 kg CO2/kg Li2CO3, destacando el impacto de la evaporación solar y el uso de reactivos químicos. Aunque tecnologías como la Extracción Directa de Litio (DLE) prometen optimizar recursos y reducir impactos, su implementación requiere superar desafíos técnicos y económicos significativos. En el aspecto económico, el costo de producción de Bolivia ($5.500/ton) para Evaporación Solar y de ($8.245/ton) para EDL. Es superior al de competidores como Chile y Argentina, que operan entre $4.000-$5.000/ton, debido a la baja eficiencia tecnológica y la alta relación Mg/Li en el Salar de Uyuni. Superar estas barreras exige inversiones en tecnologías avanzadas, diversificación hacia productos de mayor valor agregado y estrategias que equilibren sostenibilidad y competitividad.
Abstract: This study evaluates lithium carbonate (Li2CO3) production in Bolivia, addressing its position in the global value chain, the environmental impact of the production process, and its economic viability. Bolivia, despite possessing the largest lithium reserves, faces significant barriers to integration into the value chain, limiting itself to exporting intermediate products without participating in downstream stages, such as battery production, which reduces its global competitiveness. The analysis of the production process revealed a water footprint of 556.37 m3 eq. world/t and a carbon footprint of 12.5 kg CO2/kg Li2CO3, highlighting the impact of solar evaporation and the use of chemical reagents. Although technologies such as Direct Lithium Extraction (DLE) promise to optimize resources and reduce impacts, its implementation requires overcoming significant technical and economic challenges. From an economic perspective, Bolivia's production cost is $5,500/ton for Solar Evaporation and $8,245/ton for Direct Lithium Extraction. This is higher than that of competitors such as Chile and Argentina, which operate between $4,000 and $5,000/ton, due to the low technological efficiency and high Mg/Li ratio in the Salar de Uyuni. Overcoming these barriers requires investment in advanced technologies, diversification toward higher value- added products, and strategies that balance sustainability and competitiveness.
