  Nowadays, urban freight traffic is causing significant noise and air pollution, so it is in the focus of green logistics developments, both in technology and system organization. Based on experiences within city logistics, significant problems are caused by the so-called concentrated sets of delivery points, where there are several delivery points with heavy freight traffic in a relatively small area. Since the summer of 2015, we collected lots of data about stores of these delivery points to support the modelling and the simulation of the new green solutions for the examined city logistics systems. Based on our results we can say, there are significant savings in these systems, so it is worth to deal with developing new, gateway-concept-based and consolidation-based solutions.

  This study evaluates the long-term economic feasibility of electric waste collection vehicles (EVs) as a sustainable alternative to diesel-powered counterparts in urban municipal services. Using real operational data from a Hungarian waste management company, we developed a total cost of ownership (TCO) model spanning 10 years, which incorporates investment costs, energy consumption, maintenance, depreciation, and battery replacement. Our analysis reveals that although EVs require a significantly higher upfront investment (€350,000 vs. €183,200), their lower operational and maintenance costs result in a break-even point around year 8. When accounting for a €50,000 battery replacement in year 6, the total 10-year cost of the EV remains lower (€431,769 vs. €450,914) than the diesel vehicle, resulting in a net saving of €19,145. The study emphasizes the significance of local energy prices and service structures in assessing fleet electrification. While the findings are based on Hungarian data, the proposed methodology can be adapted internationally to support data-driven decision-making in sustainable waste logistics.

  This is a conceptual theory-building paper that questions the notion of a "trade-off narrative" between sustainable supply chain management. It claims that advanced Information Systems (IS) play a crucial dual function in designing the co-construction of environmental and competitive value. The paper proposes a Dual-Role framework based on an abductive analysis of modern literature, mapping the synergistic impact pathways of these technologies. The framework proposes that the Internet of Things (IoT) allows data-driven closed-loop control, blockchain provides cryptographic trust, Artificial Intelligence (AI) offers predictive intelligence for systemic leanness, and cloud platforms offer orchestration and alignment. The framework results in a series of research propositions that can be tested and specify the likely conditions for this dual value creation. We argue that strategically located IS can transform sustainability from a constraint on operations to a parameter of the design for competitive advantage. This study offers a propositional theory for scholars to guide empirical research, as well as a principled rationale for managers to view digital investments as a foundation for planetary and business resilience.
