PROPOSAL OF A FRAMEWORK FOR THE EVALUATION OF THE SUSTAINABILITY OF PRODUCT SUSTAINABILITY FROM THE PARADIGM OF THE CIRCULAR ECONOMY BASED ON INDUSTRY 4.0. (Part 2)

Abstract

Once the framework for the integrated evaluation of sustainability connected from the circular economy paradigm in the context of the cyber-physical systems of Industry 4.0 has been developed, this paper develops the methodological model that makes it possible to obtain an evaluation of the impacts of the three dimensions (environmental, economic and social impacts) by analyzing their effects (LCA) and their causes (C2C). The articulation of the model from these two frameworks (ACV and C2C) has determined that it has a structured bionic inspiration in two phases. The first of these, the adenomic phase, fixes the genes of the product through design, and in the second, the domestic phase, which integrates the aspects of sustainability derived from the phenotypic evolution of the product. Due to the digitalization of Industry 4.0, the product evolves towards the connected intelligent product equipped with sensors that collect information in real time, evolving sustainable development towards connected sustainability. The evaluation model is connected to an IoT platform composed of different processing layers and connected to external information sources to incorporate the necessary data to carry out a complete and integrated evaluation. This model supports the product data under ISO 10303 (STEP). Keywords: Circular Economy, LCA, C2C, Industry 4.0, STEP
