dc.description.abstractLa ecoeficiencia se define como una relación entre el beneficio económico percibido por un sistema productivo y el impacto ambiental generado. Dentro de las metodologías disponibles para el cálculo de este último, está el análisis emergético el cual cuantifica la cantidad de energía directa e indirecta usada para crear un bien o un servicio bajo una misma unidad, evidenciando la inversión hecha por el ecosistema en aquel producto o servicio, lo cual permite integrarse con el análisis de ecoeficiencia. De esta forma, el propósito del presente estudio es implementar el análisis emergético para el cálculo de ecoeficiencia en el proceso de tostación de una planta productora de malta cervecera, donde el consumo energético es considerable. Para el desarrollo se realizó un análisis de entradas y salidas del sistema, se aplicaron transformicidades en cada entrada y se calcularon indicadores emergéticos que caracterizan el sistema. Con estos datos, se cuantificó la emergía total requerida por el sistema y se halló la ecoeficiencia con referencia al ingreso económico, obteniendo un valor de 2.90x10-13 USD/sej, y de 6.43x10-16 ton/sej respecto a la cantidad de malta producida. Con los resultados obtenidos se sugiere reusar la energía en el proceso de calderas y tostación, disminuir el consumo de fuentes no renovables, y disminuir las pérdidas de energía del sistema, en busca de generar un mejor comportamiento ambiental. De acuerdo con esto la implementación del método emergético en el análisis de ecoeficiencia, permite identificar puntos de mejora en la relación económica y ambiental de un sistema industrial.

dc.description.abstractEco-efficiency is defined as a relationship between economic benefit perceived by a production system and the environmental impact generated. Into the methodologies available for calculating the environmental impact, there is the emergy analysis which quantifies the amount of direct and indirect energy used to create a good or a service under the same unit, determining the investment made by the ecosystem in that product or service, which allows integration with the eco-efficiency analysis. In this way, the purpose of this study is to implement emergy analysis for the calculation of eco-efficiency in the kilning process of a brewing malt production plant, where energy consumption is considerable. For that development, an analysis of inputs and outputs of the system was carried out, transformities were applied in each input and emergy indicators were calculated to characterize the system. With these data, total emergy required by the system was quantified and eco-efficiency was found with reference to economic income, obtaining a value of 2.90x10-13 USD/sej, and 6.43x10-16 ton/sej regarding the quantity of malt produced. According with that, it is suggested to reuse the energy in the boiler and kilning process, reduce the consumption of non-renewable sources, and reduce the energy losses of the system, to generate a better environmental behavior. In this way, the implementation of the emergy method in the eco-efficiency analysis, allows to identify points of improvement in the economic and environmental relationship of an industrial system.
