This study aims to mitigate these challenges through the fabrication of a novel spherical, floatable magnetic core-shell photocatalyst (NiFe<sub>2</sub>O<sub>4</sub>-Sodium Alginate@ SnO<sub>2</sub>-g-C<sub>3</sub>N<sub>4</sub>), using spinel ferrite nanoparticles (NiFe<sub>2</sub>O<sub>4</sub>) as the core and SnO<sub>2</sub>-g-C<sub>3</sub>N<sub>4</sub> catalysts as the shell. The shell was synthesized hydrothermally, while a green synthesis approach was used for the core. The fabrication involved a gelation process to combine the shell with the core, resulting in transparent spheres with improved floating capabilities after freeze-drying. The successful synthesis was confirmed through characterization techniques such as XRD, FT-IR, EDX, XPS, and FESEM. The photocatalytic efficiency was assessed by degrading Acid Red 88 in a 200 mL batch reactor under UV-C lamp irradiation as light sources, using ambient temperature as the experimental condition. Various parameters were tested, including pH levels (3, 5, 7, 9, and 11), photocatalyst dosages (0.2, 0.4, 0.6, 0.8, and 1 g/L), and dye concentrations (10, 20, 30, 40, and 50 mg/L), in order to determine the optimal conditions. The results demonstrated a removal efficiency of 97.41 % under optimal conditions of pH 11, a photocatalyst dosage of 0.4 g/L, and an initial dye concentration of 20 mg/L.

Nonetheless, their extensive use poses concerns, including a rise in throwaway batteries, which, if inadequately managed, may result in heightened human toxicity. Therefore, the establishment of a circular supply chain (CSC) for EVs is crucial for ensuring long-term sustainability. This study seeks to investigate circularity potentials of end of life (EoL) EVs, influential factors, modeling approaches, and policy interventions that promote the implementation of a CSC for EVs based on a systematic review of empirical-based literature following the PRISMA framework. The findings highlight that, under an optimized waste hierarchy, approximately 55.1–59.5 % of EV components can be reused, 24.4−31.8 % repurposed, 55.1−59.5 % remanufactured, and 95.6−96.0 % recycled, leaving about 23.5–24.7 % of components destined for landfills. Five factors pertaining to regulations, economics, environment, technology and infrastructure, ecosystem were identified to be influential for the CSC implementation for EVs. These factors are modeled using either optimization, simulation, or hybrid approach, depending on the modeling objective and settings, in order to comprehend the CSC system, support decision-making and enhance resource recovery strategies. Policy interventions primarily focused on collection and transportation, technology and infrastructure, and economic aspects, have recently been expanded to encompass social interventions, design standardization, and stakeholder collaboration. Given the potential circularity of EV components, the multifaceted factors involving various stakeholders should be addressed in designing and implementing CSC system for a more resource-efficient future of EVs.</div></div>","PeriodicalId":34618,"journal":{"name":"Cleaner Engineering and Technology","volume":"27 ","pages":"Article 101013"},"PeriodicalIF":5.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144296840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This makes energy optimization not just a necessity, but a strategic advantage for the future of the sector. While numerous studies have examined the topic of energy efficiency from a technological standpoint, there is a notable absence of research exploring the production process. This study deals with the evaluation of the energy optimization of the Martinotti-Charmat secondary fermentation process in the production of sparkling wines, in particular Prosecco DOC. Following an analysis of the process from an oenological perspective, the chemical and physical constraints associated with potential modifications aimed at reducing refrigeration energy requirements are investigated. Furthermore, an energy model of the process was developed to assess the potential benefits of alternative temperature control strategies for critical process steps, namely wine cold tartaric stabilization and subsequent storage prior to final bottling. Different scenarios for the management of these steps were simulated. The results demonstrate the feasibility of significantly reducing process energy requirements while maintaining wine quality through novel temperature control strategies, thus paving the way for improving the sparkling wine production sector in terms of energy and environmental sustainability.</div></div>","PeriodicalId":34618,"journal":{"name":"Cleaner Engineering and Technology","volume":"27 ","pages":"Article 101018"},"PeriodicalIF":5.3,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144253511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A fuzzy linear programming model is developed here to address this research gap. The model is based on an environmentally-extended enterprise input-output model, which allows consistent computation of the carbon footprint and production cost of each product. When credits are purchased from an external vendor and distributed to the firm's internal operations, both the carbon footprint reduction and the incremental cost propagate through the production system via intermediate streams. The carbon credits are allocated optimally given company-defined carbon footprint reduction targets and incremental cost limits. The model is first demonstrated in a simple pedagogical case study. It is then applied to an industrial case study of a conglomerate producing a suite of electronics hardware and software products; carbon footprints are reduced by 40 % with an incremental production cost of less than 1 % for most of the products.
