Introduction

The landscape of modern manufacturing is being reshaped by the urgent need for sustainability. A core aspect of this transformation involves integrating various sustainable technologies to support a circular economy. This approach aims to dramatically improve resource efficiency, reduce waste generation, and enhance material recycling processes. Ultimately, the goal is to foster manufacturing practices that are not only environmentally benign but also economically robust and viable [1]. In the global push towards cleaner energy, green hydrogen stands out as a promising solution. Research continues to explore diverse sustainable production methods for green hydrogen, with a strong emphasis on leveraging renewable energy sources. Key technologies like electrolysis, powered by solar and wind energy, are under scrutiny. Discussions involve their current operational status, existing challenges, and their considerable potential for broad adoption as a truly clean and sustainable fuel source. Understanding how green hydrogen can become a cornerstone of future energy systems is crucial [2].

The agricultural sector is undergoing a profound shift, driven by advancements in digital technologies. Specifically, the integration of the Internet of Things (IoT) and Artificial Intelligence (AI) is proving instrumental in cultivating more sustainable agricultural practices. A systematic review of current applications clearly demonstrates how these powerful technologies can optimize resource utilization, significantly boost crop yields, and effectively minimize negative environmental impacts. These findings collectively envision a future where farming operations are inherently smarter, more efficient, and significantly greener [3]. Addressing the twin challenges of waste management and energy demand, sustainable technologies are emerging that efficiently convert various types of waste into valuable energy products, particularly biofuels. Detailed reviews outline different thermochemical and biochemical processes, such as pyrolysis, gasification, and anaerobic digestion. Each process is carefully assessed for its operational effectiveness and the substantial environmental benefits it offers. These technologies hold significant promise for simultaneously managing waste streams and generating renewable energy, creating a dual positive impact [4].

The construction industry is making strides towards sustainability through the innovation of new building materials and practices. Recent developments in sustainable building materials offer critical insights into green construction. This includes the exploration of innovative substances like recycled aggregates, advanced bio-based composites, and even self-healing concrete. These materials are highlighted for their distinct environmental advantages and superior performance characteristics. The trajectory of this research points clearly towards developing more eco-friendly and resilient infrastructure worldwide [5]. Mitigating climate change necessitates advanced solutions for managing industrial carbon emissions. Carbon Capture, Utilization, and Storage (CCUS) technologies represent a vital pathway in this endeavor. An overview of these technologies showcases their latest advancements and explores their future prospects. This encompasses various capture methods, innovative ways to repurpose captured Carbon Dioxide (CO2), and robust, secure storage solutions. The central role of CCUS in significantly reducing atmospheric carbon and combating global warming cannot be overstated [6].

It delves into membrane bioreactors, advanced oxidation processes, and microbial fuel cells, showcasing their efficiency in purifying water and extracting resources like nutrients or energy. The insights highlight methods for making wastewater management more circular [7]. The concept of smart sustainable cities is rapidly evolving, driven by ongoing technological progress and strategic future planning. Comprehensive reviews examine the critical advancements propelling these urban environments forward. It highlights how integrated solutions, including smart grids, intelligent transportation systems, and digital governance models, collectively contribute to achieving urban sustainability objectives. The insights gained illuminate the strategies required to create cities that seamlessly blend technological sophistication with profound environmental responsibility [8].

Reliable energy storage is paramount for the effective integration of renewable energy sources into existing power grids and for reducing reliance on traditional fossil fuels. This area of study investigates sustainable energy storage technologies, detailing both recent advancements and persistent challenges. It encompasses a spectrum of solutions, from various battery types and supercapacitors to advanced thermal storage systems. The assessment of these technologies underlines their critical potential to enhance energy reliability and drive the transition away from carbon-intensive energy sources [9]. Green chemistry and sustainable chemical processes are at the forefront of efforts to minimize the environmental footprint of chemical production. Recent progress in this field is systematically summarized, revealing innovations across several domains. This includes breakthroughs in catalysis, more environmentally benign solvent selection, and refined reaction design principles. These developments are geared towards minimizing waste generation and significantly reducing the overall environmental impact associated with synthesizing chemicals. The focus remains on developing safer, more efficient, and inherently sustainable methods for chemical synthesis [10].
