This review explores the cutting-edge use of waste-derived electrocatalysts for electrochemical CO₂ reduction (eCO₂RR) to convert CO₂ into valuable chemicals and fuels. The broader implementation of eCO₂RR hinges on developing cost-effective, high-performance electrocatalysts. Over 45 waste streams encompassing electronic waste, biomass, industrial byproducts, and plastics have been examined for their potential to be transformed into functional catalysts through pyrolysis, hydrothermal synthesis, chemical leaching, mechanical separation, and hybrid recycling. These materials leverage the inherent metal content, heteroatom functionalities, and carbon-rich structures found in waste, achieving Faradaic efficiencies of up to 98 % for products including CO, formate, and methanol. The relationship between structural features and catalytic performance was emphasized, particularly how surface area tuning, nitrogen doping, and active site engineering enhance selectivity and reaction kinetics. By redefining waste as a valuable feedstock for carbon conversion, this review provides a comprehensive framework for advancing low-carbon chemical manufacturing and accelerating the transition toward a circular carbon economy.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 118051"},"PeriodicalIF":7.4,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While microalgae-based production systems have garnered significant scientific interest, their techno-economic-environmental viability is still challenged by many limitations. Key research questions emerge: What are the prospects for scaling up microalgae-based production systems? Can microalgal bioproducts achieve true sustainability? This study aims to respond with a systematic meta-review of recent literature containing economic and environmental scientific information. A narrative synthesis is combined with data collection, homogenisation, and appraisal to provide a synoptic framework that captures the latest trends from techno-economic analysis and life cycle assessment, identifying enablers and barriers within a future perspective. The analysis of production costs and GHG emissions reveals a general tendency of poor performance and competitiveness of microalgal bioproducts. However, several optimistic estimates are found within a broad variability of results. Promising strategies are the valorisation of waste streams and the implementation of multi-product biorefinery models, in line with circular bioeconomy and zero-waste principles. The adoption of low-carbon energy technologies and the direct exploitation of sunlight present a additional opportunities to abate GHG emissions. Further potential lies in incentivising pilot projects, which are essential in accelerating process maturity. From a holistic perspective, advancing sustainability will require addressing the social dimension and multi-criteria optimisation. On the other hand, legislative barriers and customer acceptability must be managed through the interaction of academia, industry, and policymakers. Such efforts are crucial to unlock microalgae’s full potential and support the microalgal industry's real-world applicability, striving to achieve enhanced market penetration through green and cost-effective production processes.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 118053"},"PeriodicalIF":7.4,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144665803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Processes such as aggregation, straining, and co-transport are considered, while a wide range of influencing parameters including particle surface charge, aqueous chemistry, pH, ionic strength, and porous media properties are analyzed for their impact. Published studies reveal that ionic strength and pH significantly impact nanoparticle transport, with higher ionic strength promoting aggregation and retention due to the compression of the electrical double layer. Colloids and viruses are influenced by factors such as attachment-detachment dynamics, and interactions with other particles. Furthermore, the transport of microplastics is governed by their surface properties, hydrophobicity, size, density, and interactions with surrounding organic and inorganic substances. These characteristics play a significant role in determining their migration through porous media. Furthermore, studies have shown that natural organic matter can act as a stabilizing agent for nanoparticles and microplastics by enhancing electrostatic repulsion, thereby increasing mobility in porous media. Conversely, the presence of divalent cations such as calcium can promote aggregation and retention, particularly under conditions of high ionic strength. Τhe importance of physical, chemical, and biological factors on particle transport in subsurface environments was highlighted.

This review examines more than 20 treatment technologies for source-separated urine with a focus on fertiliser production. The technologies reviewed include: membrane processes, physicochemical technologies, microbial electrochemical systems, and hybrid approaches. For each technology, the operating principles, nutrient recovery efficiency, advantages, and limitations are outlined. This review identifies seven urine-derived fertilisers: struvite, calcium phosphate, potash, ammonium sulphate (liquid and solid), solid fertiliser (which contains N, P, K, NaCl, and KCl), and nutrient- rich liquid (which contains N, P, and K) from existing literature. Urine-derived fertilisers showed better growth in weight and size of basil plants, and demonstrated superior N and P uptake on ryegrass and maize, compared to commercial fertilisers. While treating urine with a singular technology may not simultaneously generate N, P, and K, integrating technologies can yield more than one fertiliser product with improved process efficiency. The scope and potential scalability of various urine treatment technologies are explored by analysing lab, pilot, and large-scale investigations. Further life cycle analysis is required to support real-world adoption due to the lack of studies reporting the potential impacts of implementing large-scale urine treatment facilities.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 5","pages":"Article 117962"},"PeriodicalIF":7.4,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
