“…Indeed, being circular also means reducing energy waste and, hence, exploiting renewable energies. When designing their business model, companies should look at preserving all the resources, including energy and fuel, according to the main goal of CE (i.e., closing loops in as many areas of consumption and production as possible) [28,33]. Most recent studies [34] propose Resource Efficiency Measures (REMs) or practices that companies can implement at the supply side (i.e., supply chain, internal processes, and cost structure), at the demand side (i.e., value proposition, customer interface, and revenue streams), and throughout the life cycle (i.e., use and waste phase of products), to reduce the resources needed for their goods or services.…”
