Since the origin, lithium-ion batteries (LIB) dominated with high energy density and mature infrastructure; however, given the scarcity of lithium resources and rising cost, there has been a driving force to explore alternatives like sodium-ion battery and potassium-ion battery technologies. Among these, KIBs offer high power density, favorable K+ ion diffusion kinetics, wider range of voltage at higher potential, eliminates the formation of intermetallic compounds, is abundant and also cost-effective, unlike LIBs. KIBs can use industrial standard graphite as anode unlike NIBs but both behave similarly during ion-solvent co-intercalation. Eventually reached with versatile electrode, graphite, as anode exhibits reversible potassium intercalation and charge storage mechanism with structural constraints of larger potassium-ions and lacks stability. Herein, we introduced graphite anodes recycled from spent LIBs, regenerated as anodes for KIBs-propounding a circular economy. The optimized sample tested with an ether-based electrolyte exhibited 107 mAh/g capacity at 5 A/g and was stable for 1000 cycles at room temperature. This sustainable material suitably tailored, exhibits good electrochemical performance at both room and low temperatures. Also, the kinetics of co-intercalation mechanism was investigated using electrochemical impedance spectroscopy, ex situ x-ray diffraction and transmission electron microscopy. To a greater extent, the work highlights the positive outcomes of usage of spent graphite in advanced resource-efficient energy storage solutions. This idea keeps away resource exploitation, environmental contaminations and economic imbalances, reinforcing a sustainable circular economy.","PeriodicalId":100258,"journal":{"name":"CleanMat","volume":"3 2","pages":"111-121"},"PeriodicalIF":0.0,"publicationDate":"2026-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clem.70034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148282467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional quantification techniques such as Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Raman Spectroscopy, while effective, suffer from limitations in real-time analysis, sample representativeness, and scalability. Lock-in thermography (LIT) has emerged as a promising alternative, offering enhanced sensitivity and real-time monitoring for nanoparticle detection. In this study, we employ LIT to quantify black carbon. Two measurement configurations—transmission and reflection mode—are utilized to assess spatial distribution and concentration dependence of BC particles collected on filter substrates. Our results demonstrate a strong correlation between measured thermal signals and reference concentrations, confirming LIT's precision in quantifying BC with high reproducibility. The imaging capability further reveals non-homogeneous particle deposition patterns, which would be challenging to capture using conventional point-based techniques.

Multiple factors can considerably influence the efficiency of biogas production in AD systems. Nevertheless, understanding the fundamental principles of AD and identifying the key factors that affect biogas generation efficiency is critical. Here, we provide a comprehensive overview of the key factors influencing the AD process and a narrative review of current literature to understand progress in this field. The current review focuses on biogas production processes, particularly those involving organic waste. Subsequently, the factors affecting the AD process, such as feedstock composition, pretreatment methods, operational parameters, reactor design, and microbial community dynamics, were detailed. This review highlights that AD remains a viable solution for waste management and renewable energy production, with significant potential for efficiency improvement through optimized operating conditions, advanced reactor designs, and innovative pretreatment and microbial strategies. Moreover, the review shows that while combined pretreatment strategies may have synergistic effects on AD, their industrial adoption still requires standardized frameworks and adaptive, multi-parameter control systems for variable organic waste. This review contributes to a better understanding of AD as a viable solution to the waste crisis, while also considering its implications for sustainability.","PeriodicalId":100258,"journal":{"name":"CleanMat","volume":"3 2","pages":"74-98"},"PeriodicalIF":0.0,"publicationDate":"2026-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clem.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148282544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the bioconversion of carrot pomace (CP), waste generated in the juice industry, into fungal biomass to produce mycelium-based foams. Filamentous fungus (Aspergillus oryzae) was cultivated on carrot pomace through a submerged process in a bubble column bioreactor. The analysis of the scanning electron microscopy (SEM) confirmed the presence of the fungal mycelium and CP residues in the material recovered from the bioreactor. This material was mixed with water, and the suspension was subjected to different grinding cycles in an ultrafine grinder, and mycelium-based foams were then formed via freeze-molding and freeze-drying. The resulting foams exhibited an average density of 21.1 kg/m3, with compressive resistance values of 5.8 kPa at 10% deformation and 20.5 kPa at 30% deformation. These mechanical properties are comparable to those of commercial lightweight foams, as indicated by the Ashby material plot.

The tailored carboxyl-terminated hyperbranched architecture endowed the membrane with superhydrophilicity, underwater superoleophobicity, and a pronounced negative charge. Characterizations demonstrated that the modified membrane exhibits significantly enhanced separation efficiency and superior fouling resistance against both oil and protein contaminants. The exceptional performance is attributed to the synergistic effects of a robust hydration layer and the strong electrostatic repulsion provided by the hyperbranched molecular brush, which effectively minimize foulant adhesion.

The growing challenges and a complex suite of problems related to water pollution and scarcity demand technological innovations, reuse strategies, and sustainable solutions. Therefore, developing efficient, affordable, and eco-friendly wastewater treatment technologies is crucial. An oleaginous photosynthetic organism “microalga” has emerged as a valuable feedstock for wastewater treatment, carbon neutrality, and nutrient recovery. On the other hand, setting up microalgal biorefineries support resource recovery and biomass utilization, offering diverse bio-based products across industries. For instance, the global microalgal biofuel market is projected to reach USD 8.7 billion by 2030, while microalgal nutraceuticals including omega-3 fatty acids already command a market value of over USD 2.5 billion annually, with pigments like astaxanthin valued at USD 1500–7000 per kg. Similarly, microalgal biomass for biofertilizers and animal feed additives contributes to a market share exceeding USD 1.2 billion globally. This multifaceted approach facilitates the reduction of waste generation by enhancing production of microalgae bioproducts. Unlike terrestrial crops like soybean that require 2000–3000 L of freshwater per kg biomass, microalgae cultivation in wastewater systems can reduce the water footprint to less than 100 L per kg biomass, achieving > 95% reduction in freshwater demand. Keeping this in mind, present review instigates the integrated phycoremediation approach that aligns with circular economy goals, promoting resource recovery and reducing the carbon footprints and water footprints in the framework of regenerative and zero waste valorization.","PeriodicalId":100258,"journal":{"name":"CleanMat","volume":"2 4","pages":"297-326"},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clem.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145824413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Revalorization of plastic waste holds the promise of transforming end-of-life plastic materials towards cleaner and more sustainable product use. Cement is essential to shape the built environment by developing long-lasting, stable structures. While plastic materials have shown low adhesion with cement, the functionalization of PET (FPET) surfaces can enhance the interaction with a cementitious matrix. Herein, we present a new functionalization strategy that enables polymer-cementitious composites while enhancing the energy absorption capacity and ductility of cementitious beams. This cleaner manufacturing technique can provide an alternative application of waste polymeric products while enabling alternative market opportunities in construction. Complete standard rheological and mechanical characterization of composite cement, including fracture tests, are presented. A significant improvement in modulus of rupture, energy absorption, and ductility was observed when 12% FPET and 16% FPET were included. This suggests that the FPET is strongly bonded to cement, enabling stress transfer across the cracked surfaces, increasing ductility and energy absorption.","PeriodicalId":100258,"journal":{"name":"CleanMat","volume":"2 4","pages":"266-284"},"PeriodicalIF":0.0,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clem.70016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145848377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
