Abstract
La Economía Circular es un concepto económico vinculado al desarrollo sustentable y a la economía verde, pero que la profundiza mucho más. Apunta no sólo a reducir el impacto ambiental de las industrias y la disminución de la cantidad de desechos generados, sino que a producir bienes y servicios mediante el manejo sostenible de materiales y fuentes de energía. Consideramos que este enfoque que está basado en la observación del comportamiento de los mercados y que puede ser enriquecido con aspectos teóricos provenientes de la Termodinámica. Para ello, proponemos la inclusión de algunos conceptos como la Energía Libre de Gibbs y la irreversibilidad de los procesos, creemos que agregar ideas permite enfatizar el profundo vínculo que es posible establecer entre la Economía Circular y la Termodinámica. El objetivo del trabajo es investigar el modo en que las definiciones Termodinámicas permiten ampliar la mirada sobre los flujos relacionados con la Economía Circular. Se exponen casos del ámbito minero metalúrgico que son brevemente comentados con esta nueva aproximación. Se concluye presentando los conceptos de la Termodinámica como una ampliación de los aspectos teóricos del enfoque Económico Circular.
The Circular Economy is an economic concept linked to sustainable development and the green economy, but it goes much deeper into it. It aims not only to reduce the environmental impact of industries and reduce the amount of waste generated, but also to produce goods and services through the sustainable management of materials and energy sources. We consider that this approach is based on the observation of the behavior of the markets and that it can be enriched with theoretical aspects from Thermodynamics. To do this, we propose the inclusion of some concepts such as Gibbs Free Energy and the irreversibility of the processes. We believe that adding ideas allows to emphasize the deep link that can be established between the Circular Economy and Thermodynamics. The objective of the work is to investigate the way in which Thermodynamic definitions allow broadening the view on the flows related to the Circular Economy. Cases of the metallurgical and mining fields are presented and are briefly commented with this new approach. It concludes by presenting the concepts of Thermodynamics as an extension of the theoretical aspects of the Circular Economic approach.
