Special Issue Information

Dear Colleagues,

Environmental sustainability is an urgent global challenge that requires innovative, effective solutions to address critical issues such as resource depletion, pollution, and climate change. This Special Issue aims to explore cutting-edge innovations in technologies, strategies, and policies that promote sustainable practices across various sectors. It will provide a platform for interdisciplinary research that integrates scientific, technological, and policy-driven innovations to offer comprehensive solutions to these pressing environmental problems. Key topics will include sustainable waste management, the development of renewable energy systems, eco-friendly materials, climate change adaptation strategies, and the advancement of circular economy models. This Issue will highlight how these interconnected areas can work synergistically to drive sustainability and resilience at both local and global scales. Contributions will emphasize the practical application of innovative solutions, showcasing methodologies, real-world case studies, and technologies that can be adopted across different regions and industries. The goal is to foster research that not only deepens understanding but also leads to actionable, scalable solutions capable of mitigating environmental impacts. By focusing on the potential of new technologies and policies to create a more sustainable future, this Special Issue will support the transition to a circular economy and offer valuable insights for future research and policy-making. Ultimately, it aims to advance the scientific community’s efforts to address the complex and interconnected challenges of environmental sustainability.

Scope and purpose of the Special Issue

a. Focus

This Special Issue aims to advance environmental sustainability through interdisciplinary approaches, emphasizing innovations in technologies, strategies, and policies. The goal is to explore practical solutions to pressing environmental challenges, including resource depletion, pollution, and climate change. Topics will cover advancements in sustainable waste management, renewable energy systems, eco-friendly materials, climate adaptation strategies, and circular economy models. These topics will be examined at both the local and global scales, highlighting how interdisciplinary collaboration can drive sustainability.

b. Scope

This Special Issue covers a broad range of research areas within environmental sustainability, focusing on key topics such as:

  • Sustainable waste management and resource recovery;
  • Renewable energy technologies and energy efficiency;
  • Eco-friendly materials and green manufacturing processes;
  • Climate change adaptation and mitigation strategies;
  • Circular economy models emphasizing resource reuse and waste reduction;
  • The integration of technological, scientific, and policy innovations to drive sustainability.

This Issue invites contributions from topics such as environmental engineering, economics, policy studies, and social sciences. It will feature theoretical studies, applied research, and case studies demonstrating real-world applications of sustainable practices.

c. Purpose

The purpose of this Special Issue is to provide a platform for sharing innovative research and fostering an interdisciplinary dialog on environmental sustainability. It aims to present actionable, scalable solutions that can be applied across industries, regions, and governance systems to mitigate environmental impacts and promote sustainability. By bringing together diverse perspectives, this Issue will facilitate knowledge exchange, promote best practices, and offer valuable insights for future research and policy-making.

Relationship with the existing literature

This Special Issue will build on the existing body of literature by offering a more holistic understanding of sustainability. It integrates interdisciplinary research across environmental engineering, economics, social sciences, and policy studies, paying particular attention to socio-economic factors that influence the adoption of sustainable practices. While substantial research already exists on sustainability—covering areas such as resource efficiency, waste management, and renewable energy—this Issue will make a unique contribution by integrating technological innovations, policy advancements, and practical applications across various sectors.

The Special Issue will complement existing research by:

  1. Expanding interdisciplinary approaches: Unlike the current literature which often focuses on specific disciplines, this Issue will bring together diverse fields to create a comprehensive understanding of sustainable development.
  2. Bridging theory and practice: Much of the existing literature is centered around theoretical frameworks. In contrast, this Special Issue will emphasize actionable, real-world solutions through case studies, methodologies, and examples that can be implemented at local, national, and global levels.
  3. Addressing socio-economic aspects: While ecological and technological challenges are often the focus, this Issue will also explore how policies, laws, and socio-economic factors influence the success and adoption of sustainability practices.

By supplementing the existing literature, this Special Issue will help define, measure, and quantify sustainability, providing tools for evaluating sustainability performance across diverse sectors. It will also contribute to policy development by offering evidence-based recommendations and solutions for addressing the complex, interconnected challenges of environmental sustainability.

When power system equipment fails due to disasters, resulting in the isolation of parts of the network, the loads within the isolated system cannot be guaranteed a continuous power supply. However, for critical loads—such as hospitals or data centers—continuous power supply is of utmost importance. While distributed energy resources (DERs) within the network can supply power to some loads, outages may lead to compensation and fairness issues regarding the unsupplied loads. In response, this study proposes a methodology to determine the appropriate power contract price for key customers by estimating the unsupplied power demand for critical loads in isolated networks and incorporating both outage compensation costs and voltage stability penalties. The microgrid under consideration comprises DERs—including electric vehicles (EVs), fuel cell electric vehicles (FCEVs), photovoltaic (PV) plants, and wind turbine (WT) plants—as well as controllable resources such as battery energy storage systems (BESS) and hydrogen energy storage systems (HESS). It serves both residential load clusters and critical loads associated with social infrastructure. The proposed methodology is structured in two stages. In normal operating conditions, optimal scheduling is simulated using second-order conic programming (SOCP). In the event of a fault, mixed-integer SOCP (MISOCP) is employed to determine the optimal load shedding strategy. A case study is conducted using the IEEE 123 bus test node system to simulate the outage compensation cost calculation and voltage penalty assessment processes. Based on this analysis, a contract price for key customers that considers both disaster-induced outages and voltage impacts is presented. Full article
