This study presents a critical analysis of the sustainability of solar energy systems within the planetary boundaries framework, which sets the limits within which humanity can safely operate. Given the substantial contribution of the energy sector to global greenhouse gas emissions, solar energy has emerged as a crucial element in the shift toward a sustainable energy future. Nevertheless, numerous challenges impede solar energy systems reaching optimal effectiveness, encompassing technological and methodological sustainable tools constraints, environmental impacts, and socioeconomic implications. This research aims to comprehensively assess these challenges and propose strategies to surmount them through applying a Life Cycle Sustainability Assessment approach. The primary research question addressed is, "How reliable are the predictive and anticipatory assessment methods for sustainable solar energy systems within our planetary boundaries?" The study integrated circular economy principles, criticality evaluation, and advanced technological tools to enhance solar energy systems’ efficiency, environmental performance, and socioeconomic benefits. By addressing the entire life cycle of solar technologies — from material extraction to end-of-life (cradle-to-grave) — this work seeks to contribute to developing more sustainable solar energy systems that operate within the safe limits of our planet’s boundaries. The findings highlight the need for a holistic approach that not only focuses on technological advancements but also considers the broader environmental and socioeconomic impacts to ensure a truly sustainable energy transition.

Chemical cross-linking in membrane fabrication aims to face limitations of polymer membranes, including poor chemical resistance, low mechanical stability, swelling, etc. Typical cross-linkers do not fit green chemistry and sustainable principles due to their toxicity. Thus, this article discusses the successful application of green cross-linkers (including organic acids — citric, gallic, ferulic, and tannic acid, calcium chloride, deep eutectic solvents, pectin) and less toxic substances in polymer membranes (including biopolymeric ones based on chitosan or cellulose) fabrication. This article also mentions how to make it ‘greener’. Important areas for these developments include food biopackaging materials, 3D printing materials, and biomedical items.

Polymer-based membrane technologies aim to address critical needs for separation, purification, transport, wound healing, contaminant removal, and more. While robust performance from these membranes is a priority, there is also a pressing need for sustainable, cost-effective solutions for membrane materials to replace perfluorinated and petroleum-derived polymers, which pose significant environmental concerns. Lignin, the second most naturally abundant polymer and a waste by-product of pulp and paper industries and cellulosic biorefineries, offers immense potential to drive sustainable materials revolution. This largely underutilized biopolymer possesses many physical and chemical attributes, making it suitable for biomedical, environmental, and energy applications. For instance, lignin and its functionalized derivatives offer antimicrobial, antioxidant, ultraviolet (UV)-blocking, and barrier properties, which are essential for slow drug release, wound healing with reduced stress, combating antibiotic resistance, and sterile food packaging/preservation. On the other hand, lignin’s 3D, hyperbranched architecture, phenolic units, and facile functionalization opportunities enable unique physical, mechanical, thermal, chemical, and ion transport/separation characteristics, critical for clean water and clean energy technologies. Therefore, by transforming lignin-rich biomass feedstock and industrial waste into value-added, efficient products, we can potentially address global needs for clean water, safe food, affordable healthcare, and renewable energy, as outlined in the United Nations’ Sustainable Development Goals. This mini-review highlights recent advancements in lignin-based membrane designs for biomedical, environmental, and energy applications, alongside a brief discussion on rooms for improvement in this emerging field via lignin valorization.

Incorporating green hydrogen production into photoelectrochemical (PEC) wastewater treatment has been demonstrated as a promising approach to enhance the sustainability of wastewater treatment. Such a bifunctional PEC system eliminates the dependence of water splitting on pure water consumption and enables wastewater valorization. This critical review initially delves into the advances in developing photoelectrodes for bifunctional PEC systems and summarizes the involved modification approaches. Subsequently, the review provides a comprehensive analysis of strategies for optimizing the operation of bifunctional PEC systems and impacts from the wastewater matrices. Furthermore, the challenges presented in the industrialization of this technology are also pointed out. As such, further investigations are encouraged into the scale-up of the PEC reactor, the prolongation of photoelectrode lifespan, the development of downstream hydrogen storage techniques, cost-effectiveness assessment, and the strategy against external variations, thus advancing the bifunctional PEC technique toward industrialization.

This perspective paper presents a focused review of a selected topic of chemical-based products, namely, formulations. As formulations cover a wide range of chemical-based products, we highlight opportunities for innovation in three types of formulations — liquid blends, which are mixtures of chemicals that are in the liquid state at standard conditions; liquid formulations, which are mixtures of chemicals that may exist in different states but the final product is a single-phase liquid; and emulsions, which are also mixtures of chemicals that may exist in different states, but the final product is in the form of an emulsion. In each case, we discuss aspects of design, analysis, and innovation together with issues and challenges that could be tackled to find better and more sustainable products. In particular, the potential of hybrid artificial intelligence augmented computer-aided techniques that can aid in the design, analysis, and innovation of formulations is highlighted.

Surface patterning of membranes has demonstrated significant performance enhancements in various membrane-based technologies. Surface patterns can increase the effective membrane area, improve interfacial area, and enhance hydrodynamics, leading to better membrane properties. Such patterns have been successfully fabricated on a lab scale using template-based molding and direct fabrication process. However, transitioning these techniques to commercial-scale production presents challenges, including maintaining pattern fidelity, ensuring reproducibility and scalability, achieving cost-effectiveness, and avoiding pattern-induced defects. This short article focuses on the emerging field of surface patterning of membranes, exploring different techniques for pattern creation and their effects on membrane properties, structure, and performance. The practicality, sustainability, and scalability challenges of each technique are thoroughly evaluated to determine their potential for commercialization and broader application in membrane technology. The essential steps and future directions needed to address these concerns and limitations are discussed, and a framework for evaluating surface patterning techniques is proposed to stimulate future research and development, advancing the commercial viability and reliability of surface-patterned membranes in the membrane technology industry.

This paper explores recent advancements and future directions in the application of modeling and simulation for pharmaceutical process development. As the rising cost of drugs becomes a global concern, particularly in countries like Japan, where manufacturing costs and research and development (R&D) expenses significantly influence drug pricing, there is growing interest in leveraging digital technologies to enhance efficiency and reduce costs. While modeling and simulation hold promises for streamlining R&D and lowering manufacturing expenses, the full extent of their impact remains to be clarified. This paper discusses the key factors that must be considered to maximize their effectiveness, providing an overview of recent studies in three key modalities: small molecules, biopharmaceuticals, and regenerative medicine. The paper concludes by emphasizing the need for long-term investment to fully realize the potential of modeling and simulation in this field.

Membrane technology offers the potential for low-footprint solutions for industrial separation processes. However, using hazardous and conventional toxic solvents in membrane fabrication has raised sustainability concerns, prompting researchers to seek safer, bio-based solvent alternatives. Further disposal of used membranes is problematic. Both these concerns adversely affect the overall life cycle analysis. Green chemistry principles aim to reduce hazardous substances in chemical applications. Many studies have explored replacing conventional toxic solvents with less harmful green solvents. This opinion article covers the most recent trends, challenges, future directions, and advancements in sustainable membrane manufacturing over the past 4 years. These advances will lead to more sustainable membrane processes.

Solar radiation–based green H2 evolution has emerged enormous interest due to photocatalysts hastening the solar energy conversion into chemical energy and repeating the cycle performance. Recently, CdIn2S4 (CIS) n-type semiconductors and metal-organic frameworks (MOFs) having high-porous structures have emerged as excellent photocatalysts for green and sustainable energy generation due to their specific properties (e.g. durability, high surface area, tunable band gap, etc.). Novel composites based on combining CIS and MOFs enable broad light absorption, better separation, and transport of photogenerated carriers, improving solar energy utilization. In particular, charge migration at the interface between MOFs and CIS is noteworthy that the accumulation of photogenerated electrons on CIS conduction band causes remarkable enhancement of photocatalytic H2 production. Covering the literature articles of the past 3 years, this mini-review presents efficient photocatalysts via simultaneous cooperation of CIS and MOF engineering as well as promising materials in H2 production. First, this work illustrates applications of CIS- and MOF-based photocatalysts for solar H2 evolution fabricating advanced photocatalysts with superior absorbed visible light. Last, future perspectives and challenges on emerging CIS- and MOF-assisted heterojunctions are provided, which create novel designs for materials by coupling CIS and MOF morphologies to create clean energy generation.
