The application of carbon dots (CDs) provides a simple, highly selective, sensitive, and cost-effective method for antibiotic sensing. Fluorescence-based CDs have shown great potential as sensors for antibiotic detection. However, variations in their production and surface properties pose challenges in understanding the underlying detection mechanisms and achieving consistent high sensitivity. This review provides a comprehensive overview of the production, fluorescence mechanism, and application of CDs for fluorescence-based detection of antibiotics in aquatic environments. It examines the key principles behind CD-based detection, focusing on sensitivity, selectivity, stability, and ease of use. Recent advances in CD synthesis and factors affecting fluorescence are discussed, along with the sensing mechanisms and challenges in detecting antibiotics in water. The review outlines future research directions to improve the sensitivity and selectivity of carbon dots (CDs) for practical applications, highlighting their potential in mitigating antibiotic contamination in wastewater. It also discusses design strategies for enhanced molecular recognition in complex matrices, the limitations of carbon-based nanomaterials, and the challenges associated with industrial-scale implementation. Additionally, the toxicity, biocompatibility, and biodegradability of CD-based sensors for in vivo applications are critically examined.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 3","pages":" 1230-1251"},"PeriodicalIF":4.9,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/su/d5su00816f?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388502","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}

Biobased alternatives offer a promising pathway to reduce fossil fuel dependence, yet their benefits remain underexplored, particularly in forward-looking assessments. Here, we present a cradle-to-gate and prospective life cycle assessment (pLCA) of a novel biobased secondary polyol ester (SPE) lubricant base oil developed by an industrial manufacturer, using high-resolution primary data from a commercial-scale production facility. The assessment incorporates Shared Socioeconomic Pathway scenarios (SSP1 and SSP2) modeled with the IMAGE integrated assessment model. The results show that SPE base oils reduce greenhouse gas emissions by up to 41% relative to fossil-derived polyol ester (DITA), and up to 84% when biogenic carbon uptake is considered. Performance is comparable to or better than both DITA and the European biobased ester LIGALUB 19 TMP across impact categories, including acidification and eutrophication. However, the analysis also reveals burden shifting: while GWP and cumulative energy demand decrease, freshwater ecotoxicity and ozone formation potential remain elevated due to upstream agricultural and chemical inputs. Fatty acids and polyols were identified as the dominant environmental hotspots, contributing over 80% to several categories. Geospatial and prospective modeling further show that regional electricity grid composition and global decarbonization pathways can moderately affect outcomes, with SSP1 scenarios offering future reductions. This case study advances the life cycle understanding of industrial biobased intermediates, emphasizing both the promise and complexity of low-carbon lubricants. Future progress will require integrated feedstock optimization, cleaner energy sourcing, and stronger alignment with circular economy principles.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 5","pages":" 2337-2354"},"PeriodicalIF":4.9,"publicationDate":"2026-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/su/d5su00641d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147924045","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}

Chemical upgradation of plastic pyrolysis oil offers a practical route to improve fuel compatibility and usability. The proposed treatment approach shows flexibility across different feedstock conditions, supporting its relevance for closed-loop plastic recycling. This study investigates the catalytic cracking of upgraded waste plastic pyrolysis oils (PPO), including chemically treated (CPO) and distilled (DPO) pyrolysis oils. Cracking was done using Equilibrium Catalyst (E-CAT) in a fixed-bed reactor, operating within the temperature range of 500 °C to 600 °C to produce light olefins (C2–C3). The influence of DPO, CPO, and PPO on product distribution and catalyst performance is examined. The findings reveal that DPO yields the highest cracking toward light olefins, with a yield of 61.1 mol% at 550 °C and a WHSV of 2 h−1 as compared to CPO and PPO. In contrast, CPO and DPO resulted in higher conversions of methane (26.4 mol% and 25.7 mol%, respectively), followed by the lowest in DPO (17 mol%). Time-on-stream analysis (TOS) revealed that DPO's lighter olefin conversion has declined, particularly in ethylene yield from 31.09 mol% to 12.13 mol% over time as compared to CPO, which maintained an ethylene yield of 23.5 mol%. This study contributes to the prospect of upgraded PPO as an alternative to naphtha feed under optimized reaction conditions, such as temperature and WHSV, for high yields of olefins in a petrochemical unit.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 4","pages":" 1933-1942"},"PeriodicalIF":4.9,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/su/d5su00937e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686511","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 paper presents a two-step continuous-flow process for choline chloride production only from common biomass-derived precursors. Using water as the solvent, the method delivers 99% pure choline chloride and can generate NaCl as a byproduct depending on the base used. With a residence time of just 1 minute, the process reaches full conversion, achieving a 20-fold improvement in productivity compared to batch operation and enabling annual throughputs of up to half a ton per microcapillary. A comprehensive sustainability assessment highlights the advantages of using choline hydroxide (Ch-OH) as the base. When using Ch-OH, the process requires substantially less material and generates no byproducts, leading to a 51% reduction in energy demand and a 24% decrease in overall environmental impacts relative to NaOH. These benefits arise from lower input requirements, reduced wastewater generation, and higher process efficiency. Circularity performance also improves with Ch-OH, and life cycle assessment confirms that increased productivity outweighs the higher impacts associated with its production. Overall, the combined flow chemistry and Ch-OH strategy offers a highly efficient and more sustainable route to choline chloride.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 6","pages":" 2565-2580"},"PeriodicalIF":4.9,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/su/d5su00480b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148214951","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}

Impact Lab explored global sustainability through three thematic modules focused on: (i) climate change, sea-level rise, CO2 absorption, and ocean acidification; (ii) soil and water quality, nutrient cycles, and ecological consequences of fertilizer runoff; and (iii) biodiesel synthesis via transesterification, highlighting green chemistry's role in renewable energy and waste valorization.

However, increasing concerns about the toxicity of FRs make it relevant to evaluate their net impacts. This study presents a methodological approach for comparing products with and without FRs based on life cycle assessment (LCA) and incorporating quantitative health risk assessment. Sofas with and without melamine FRs are compared, considering environmental and health impacts from cradle to grave. The assessment considered 19 midpoint categories and human health as an endpoint category (measured in disability-adjusted life years). For the midpoint-level LCA results, the main contributing processes are the production of the wooden sofa frame, followed by the polyurethane foam, and then the sofa's waste treatment. The contribution of the melamine FR to the overall impact is small, mainly due to the low quantity used (approximately 4.4% of the sofa's weight) and the relatively low toxicity of melamine. The avoided relative health impact from fire-related fatalities is larger than the health impact from melamine FR emissions. As a result, the net human health impact is lower for the sofa with melamine FRs. This approach provides a clearer understanding of the trade-offs involved in using FRs in furniture.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 3","pages":" 1593-1605"},"PeriodicalIF":4.9,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/su/d6su00022c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388500","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}

These methods were originally designed for simple, low molecular weight substances, and we explore their limitations when applied to complex PLFs, such as solubility contraints, structural complexities and alignment of test conditions with realistic environmental fates.

This work reports a sustainable route for the synthesis of a novel class of itaconamide monomers derived from essential amino acids (alanine, valine, isoleucine, and phenylalanine) via the direct, solvent-minimised ring-opening of itaconic anhydride. This approach avoids chlorinated reagents and activation steps, aligning with green chemistry principles. The monomers were incorporated into photocurable formulations (up to 40 mol%), demonstrating highly tunable mechanical properties: aliphatic derivatives acted as efficient plasticizers, increasing elongation at break by up to 385%, while phenylalanine moieties provided network reinforcement via π–π interactions. Thermal analysis confirmed stable glass transition temperatures combined with enhanced char yields. Crucially, a quantitative sustainability assessment yielded a Sustainable Formulation Score (SFS) of up to 51.8, significantly outperforming current state of the art bio-based resins.

Conventional wastewater treatment processes have been inefficient for the elimination of these contaminants, resulting in their sustained accumulation. Among advanced oxidation processes (AOPs), photocatalysis has garnered notable attention as an effective method for the degradation of organic pollutants owing to its ability to achieve complete mineralization. However, the degradation performance of conventional single and binary composites remains constricted by rapid electron–hole recombination, limited light absorption ability, and material instability. Recent research has been focused on the development of ternary composite systems incorporating conducting polymers, which synergistically utilize the unique advantages of organic and inorganic components to enhance the photocatalytic efficiency. Particularly, polyaniline (PANI) has emerged as a promising conducting polymer owing to its simple synthesis, tunability, electrical conductivity, environmental stability, and efficient electron transport properties. This review provides a comprehensive analysis of the synthesis and properties of PANI and its application in ternary composites. The PANI-based ternary composites have been further evaluated for their synthetic routes, photocatalytic degradation mechanism, applicability, stability, and reusability, confirming their efficiency as photocatalysts. Additionally, their key challenges and limitations are critically evaluated, and future research directions are proposed to advance PANI-based ternary composites for sustainable wastewater treatment.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 3","pages":" 1252-1284"},"PeriodicalIF":4.9,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/su/d5su00570a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388503","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}
