Assessing the Sustainability of Industrial Equipment Life Extension Strategies through a Life Cycle Approach: Methodology and Practical Guidelines

Abstract

Nowadays, Circular Economy (CE) is shifting from a nice-to-have marketing operation to a business development strategy that is central to the restoring and preservation of our natural ecosystem. However, despite motivated promotion efforts, the concrete application of this model at the micro-level is still in its infancy due to several challenges that companies face. One of these challenges is the uncertainty that businesses have in the estimation of the actual impact that adopting CE strategies can have on their activities from an environmental and economic perspective. This work aims to define a conceptual framework to be applied to the Life Cycle Extension Strategies (LCES) of products, which is meant to understand whether the application of a strategy is beneficial from an environmental and economic point of view. In order to address the identified need, a list of indicators to be exploited in the LCES performance analysis has been designed and divided into the two categories of environmental and economic indicators. On the top of this, a calculation methodology that is based on life cycle perspective approaches is applied, which exploits a gap-based approach and thus, compares the effects generated by the linear strategy and those created by the LCES analysis. The evaluation approach is meant to highlight the possible advantages and disadvantages offered by the CE model for product lifecycles. The conceptual framework is tested through an industrial case study and further analysis leading to the improvement of the calculation methodology is discussed.
