Among these, the anion exchange membrane (AEM) formed from the strongly charged polyelectrolyte pair, poly(sodium 4-styrenesulfonate) (PSS) and poly(diallyl-dimethylammonium chloride) (PDADMAC) stands out due to its excellent chemical stability. However, the performance of this membrane is limited by its comparatively low fixed charge density. To address this limitation, we aimed to enhance the fixed charge density through incremental PDADMAC overcharging during the complexation step, followed by optimisation of hot-pressing conditions to produce dense, freestanding films. This approach allows for precise control over membrane charge and improves the reproducibility of films, thereby overcoming challenges in the processing and handling of non-stoichiometric PECs. NMR spectroscopy was used to quantify the fixed charge of the saloplastic AEMs before and after testing, providing a reliable and time-efficient method for assessing stability. Our results showed that a PDADMAC overcompensation of ∼30 mol% optimised the fixed charge density without compromising membrane stability. The enhanced membrane exhibited an 84% improvement in ionic conductivity (4.3 ± 0.3 mS cm<small><sup>−1</sup></small> in 0.5 M KCl) compared to the original membrane. Notably, all membranes displayed excellent permselectivity (&gt;90%) in 0.1 M KCl, and at higher electrolyte concentrations, a moderate improvement in permselectivity was observed with the increase in fixed charge density.

This plastic waste represents a significant environmental challenge and reflects a major economic loss. Catalytic methods capable of transforming plastic waste into valuable chemicals and fuels offer the opportunity to turn plastic pollution into a viable resource, promoting a circular plastic economy that is crucial for achieving sustainability in energy sectors. This review examines the latest research advancements in catalytic processes for recycling plastic waste into chemicals and fuels. These technologies are emerging as potential solutions in the search for a sustainable circular plastic economy and energy markets, offering alternatives that incineration and mechanical recycling have largely failed to deliver. Various catalytic processes are comprehensively accessed, including pyrolysis, hydrocracking, chemolysis, hydrogenolysis, photocatalysis, electrocatalysis, biocatalysis, and metathesis, which efficiently convert plastic waste into valuable chemical building blocks, fuels, and other high-value products. These technologies not only address the environmental issues associated with plastic pollution but also contribute to resource recovery and energy sustainability with potential to produce low-carbon fuels, chemicals and building blocks to enhance plastic circularity. Moreover, this review addresses the current challenges and future research directions essential for accelerating the transition towards sustainable circular plastic economy. It offers a comprehensive evaluation of catalytic recycling technologies, including pyrolysis, hydrocracking, chemical depolymerisation, and metathesis, with a focus on mitigating Scope 3 Emissions and fostering sustainable energy solutions. The objective is to promote the advancement of catalytic technologies, recognizing the potential of catalysis to enhance economic efficiency and capitalize on the conversion of plastic waste into high value chemical feedstocks and energy. The review highlights recent developments in catalytic processes, including catalysts, plastic feedstocks, reaction parameters, and their impact on product distribution and yield.

In this study, we demonstrate that dihydrolevoglucosenone (Cyrene), a green solvent, in combination with microwave irradiation, leads to a substantial reduction in reaction time by several orders of magnitude (a few minutes instead of hours or days) with good to excellent yields. In certain instances, precipitation is a sufficient method for the removal of high boiling Cyrene, resulting in an approximate 70 fold improvement of molar efficiency (Mol E.%) compared to standard procedures. In case of more lavish purification, Dry Column Vacuum Chromatography (DCVC) has been demonstrated to be a suitable purification approach, characterised by its expeditious nature and its significantly reduced generation of organic waste in comparison with conventional column chromatography. Building on this and in addition to the green synthesis, an ultra-low cost and highly efficient chromatographic method, based on similar principles to the DCVC, has been developed, resulting in a 12 fold improvement in the E-factor <em>versus</em> column chromatography.

Several processes are currently available for producing biofuels, of which ethanol and biodiesel are the best known. Other fuel alternatives are emerging, some of which are attracting attention due to their high treatment capacity and the production of aromatic compounds needed to ensure fuel compatibility with conventional fossil fuels. The thermal processing of biomass has proven to be an interesting ally in the rapid transformation of materials to obtain several valuable by-products that can be properly processed to obtain drop-in fuels. Among the different thermal technologies for biomass conversion is hydrothermal liquefaction (HTL). The process has a long history of research experience and is one of the most promising technologies for substituting conventional fuels. However, due to the inherent operational difficulties of the process, many aspects still require further research before it can be considered a feasible solution. The HTL process is carried out in the presence of water under moderate temperature and high pressure, resulting in the breaking of organic molecules and repolymerization to form a gas, oil and solid fraction, the yield of which is highly dependent on the characteristics of the raw material and the process conditions.

The authors asserted that an activated orange peel-derived hard carbon (AOPDHC) can be used as an anode for sodium-ion batteries, yet the evidence for this claim was lacking. This work therefore sought to utilize ML to verify the claim by investigating the reversible capacities of AOPDHC at different initial coulombic efficiencies (ICE) and current densities. Data used to train the algorithms were mined from literature and applied in a 4 : 1 training-to-testing data split. Models that gave good correlations between experimental and predicted capacities for some assumed unknowns were used to predict the reversible capacities of AOPDHC. The maximum capacity obtained for AOPDHC was 341.1 mA h g<small><sup>−1</sup></small> at a current density of 100 mA g<small><sup>−1</sup></small> and an ICE of 48% and the minimum capacity was 170.3 mA h g<small><sup>−1</sup></small> at a current density of 100 mA g<small><sup>−1</sup></small> and an ICE of 43%. Lastly, the modeling found ICE to be a very important factor that influences the reversible capacities of hard carbon anodes for sodium-ion batteries, which matches literature findings, and possibly validates the modeling procedure.
