The Circular Economy Package issued by the European Commission in December 2015, fosters a radical change in production processes in order to facilitate the transition from a linear economic approach to a circular paradigm, preserving resources, and stimulating a sustainable economic growth. This study focuses on a prospective analysis carried out to develop and apply the circular economy concepts to optimise resource management of an automotive manufacturing plant. The aim is to identify the productive steps with the highest energy efficiency potential and prioritize measures and technologies to reduce carbon emissions and enhance energy saving, recycling, and reuse of waste materials. To this issue a partial equilibrium model has been developed based on the ETSAP Integrated MARKAL-EFOM System (TIMES) paradigm. Such a model allows a comprehensive evaluation of current energy and material flows, from supply to demand, focusing on tri-generation of cooling, heat and power (CCHP) and energy consumption within different shops (press, body, paint and assembly) and manufacturing process technologies. Moreover, a scenario analysis will allow analysing the technical-economic feasibility and environmental sustainability of such an exemplar automotive plant under different user-defined constraints (e.g. energy prices, technologies availability, environmental policy limitations, etc.) in order to identify minimum cost configurations of the entire production system in contrasting scenarios. A cost-benefit assessment will integrate the analysis of results by scenario in order to identify the "robust" strategies" for the achievement of relevant energy and environmental targets as well as to define the energy-technology roadmaps by scenario and the R & D priorities.

Abstract
The Circular Economy Package issued by the European Commission in December 2015, fosters a radical change in production processes in order to facilitate the transition from a linear economic approach to a circular paradigm, preserving resources, and stimulating a sustainable economic growth. This study focuses on a prospective analysis carried out to develop and apply the circular economy concepts to optimise resource management of an automotive manufacturing plant. The aim is to identify the productive steps with the highest energy efficiency potential and prioritize measures and technologies to reduce carbon emissions and enhance energy saving, recycling, and reuse of waste materials. To this issue a partial equilibrium model has been developed based on the ETSAP Integrated MARKAL-EFOM System (TIMES) paradigm. Such a model allows a comprehensive evaluation of current energy and material flows, from supply to demand, focusing on tri-generation of cooling, heat and power (CCHP) and energy consumption within different shops (press, body, paint and assembly) and manufacturing process technologies. Moreover, a scenario analysis will allow analysing the technical-economic feasibility and environmental sustainability of such an exemplar automotive plant under different user-defined constraints (e.g. energy prices, technologies availability, environmental policy limitations, etc.) in order to identify minimum cost configurations of the entire production system in contrasting scenarios. A cost-benefit assessment will integrate the analysis of results by scenario in order to identify the "robust" strategies" for the achievement of relevant energy and environmental targets as well as to define the energy-technology roadmaps by scenario and the R & D priorities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
