In recent years, the recovery of bioactive substances from biomass has been widely studied for obtaining high-value products, such as phenolic compounds and polyphenols. The ultrasound-assisted extraction (UAE) has gained recognition as an effective technique for extracting compounds with lower solvent, time, and energy requirements, compared to conventional processes (e.g. Soxhlet). The introduction of greener solvents for extraction procedures, such as natural deep eutectic solvents (NADES), arose as a safer option than conventional organic solvents like methanol. The synergy of UAE-NADES processes can provide extracts of biocompounds with enhanced total phenolic content and superior antioxidant activity compared to extracts with conventional solvents. Using different hydrogen bond acceptors and hydrogen bond donors for NADES synthesis can generate solvents suited to diverse applications. This review aims to briefly present the status of UAE-NADES applications published from 2021 to 2024, exploring their key uses and benefits.

The detection of microplastics is crucial, given their widespread occurrence as a global contaminant. Although numerous techniques exist for identifying small plastic particles, optical methods are increasingly acknowledged as efficient tools, particularly due to their noninvasive nature. The sub-nanoscale wavelength of light enables the identification of the unique characteristics of microscopic plastic particles through the use of technologies that integrate applied optics. This paper presents a comprehensive perspective of the various optical approaches used for the accurate detection and analysis of microplastics across different environmental settings.

Next-generation polymeric membranes must be derived from more environmentally friendly materials that have similar solubility and miscibility properties as their predecessors to form permeable and selective membranes. Bio-derived polymers, recycled plastics, and eco-friendly solvents have been demonstrated to produce membranes with similar permeability and selectivity as conventional counterparts, though matching membrane durability and cost-effectiveness remain as future research challenges. Slot die coating and 3D printing have been demonstrated to show the scalability of membrane fabrication. Life cycle assessments have become valuable tools in estimating the total environmental impacts of the manufacturing process and characterizing the sustainability of new materials. Recent advances have shortened the gap between materials innovation research and commercial application.

Spiral wound membrane elements made from flat sheet polyamide thin film composite (TFC) membranes have been successfully used in industrial water and wastewater treatment processes for several decades. This membrane configuration, offering high packing density and a small footprint, is the standard design for nanofiltration and reverse osmosis processes. Despite its industrial advantages, the manufacturing of spiral wound membrane elements relies heavily on materials derived from crude oil. This review summarizes recent progress in developing sustainable spiral wound TFC membrane elements using various approaches, including green solvents, polymers/monomers sourced from renewable or recycled materials, and fabrication techniques that eliminate hazardous solvents. While promising results have emerged from relevant laboratory studies, there is a notable absence of case studies, patents, or publications from prominent membrane manufacturers on this topic. Recognizing the significance of sustainable manufacturing in mitigating environmental impacts and optimizing resource efficiency, we foresee continued and focused efforts on this subject in the near future.

Ionic liquids (ILs) have recently emerged as a new membrane material for efficient separation. In this review, current achievements of nanofiltration (NF) membranes modified by ILs are highlighted. ILs, comprising cations and anions, possess excellent tunability of functionalized groups, high polarity, high chargeability, good antimicrobial properties, low vapor pressure, and eco-friendly characteristics, which can enhance the hydrophilicity and chargeability of the NF membrane, provide additional water transport channels and water transport efficiency, as well as improve the ion selectivity, antifouling, and antibacterial properties of the NF membrane for green and sustainable separation process. Meanwhile, the challenges and future research interests toward the interaction behavior between ILs and targeted substance, the regulation of membrane surface interface properties, the separation mechanism, and the inadequacies of s-based NF membranes are discussed.

Integrating adsorbents and electrochemistry to advance selective wastewater phosphate separations

Excessive discharges of phosphorus from wastewater streams and agricultural soils have perturbed natural aquatic ecosystems by causing environmental issues like eutrophication. Reimagining liquid waste streams as potential feedstocks can recover valuable phosphate products and decrease reliance on phosphate rock mining for fertilizer production. This perspective underscores the significance of integrating adsorbents and electrochemistry as selective separation techniques, aiming to overcome the current limitations of phosphorus recovery techniques and enhance phosphorus recovery from waste. Compared to existing methods, efficient recovery methods are expected to exhibit reduced energy demands along with improved attributes such as enhanced selectivity, increased capacity, and greater reusability. Achieving these characteristics requires advances in mechanistic understanding of the molecular-level interactions driving the performance of adsorbents and electrochemical approaches. To guide material development, process performance, and mechanistic understanding, we discuss the potential of synchrotron-based techniques (e.g., X-ray imaging and spectroscopy) to assess adsorption mechanisms and processes that degrade the performance of phosphorus recovery approaches over time, including electrode degradation, precipitation, and fouling. Leveraging these molecular insights alongside life cycle analysis and technoeconomic assessments can directly guide process engineering decisions, improving wastewater-derived phosphorus product purity, uniformity, and overall value.

Electrodialysis (ED) is a viable technology for treating unconventional waters due to its higher chemical and mechanical stability and less propensity to fouling and scaling compared to other membrane technologies. With the advances in electro-driven separation processes, ED has become a multipurpose technology capable of brine treatment, mineral recovery, chemical production, and desalination. Modeling has assisted in developing new ion-exchange membranes (IEMs) and optimizing operating parameters to enhance ED performance. Still, there is an opportunity to extend ED modeling for resource recovery by including computational-aided membrane development that will help identify new selective IEMs and reduce the experimental testing by acting as a membrane screening tool. Additionally, a multifunctional optimization approach using machine learning or artificial intelligence will enable the simulation and optimization of experimental parameters, leading to reduced experimental testing and minimized levelized cost of production.

The development of ion-exchange membrane (IEM) technologies is critical to achieving global sustainable development goals in the sectors of water desalination, energy storage, and chemical production. However, the commercialization of these technologies hinges on enhancing their techno-economic viability, which can be achieved by improving IEM performance. In this work, we review the economic feasibility of several IEM processes, highlighting common challenges that need to be addressed to improve their viability. Aqueous separation technologies show the most promise, while energy and chemical production technologies require both improvements in IEM performance and reductions in stack costs to become economically viable. By analyzing the IEM contribution to capital and operating costs, we identify materials design criteria for reducing electrochemical inefficiencies and achieving cost targets for membrane production.
