Herein, we successfully fabricated superhydrophic-superoleophilic green ceramic hollow fibre membrane prepared from sugarcane bagasse waste and modified through sol-gel method. Later, this study aims to optimize wastewater behaviour (pH, concentration and temperature) for oily-wastewater separation through green ceramic membrane using central composite design (CCD) of response surface methods (RSM). The three effective parameters analyzed were oil pH (3–11), oil concentration (10–10000 ppm), oil temperature (30–100 °C) and its combined effect to obtain high oil flux and excellent oil separation efficiency. Through the investigation it was found that the optimum value of pH, oil concentration and temperature were 10, 10.01 ppm and 69.04 °C. The result of the study has suggested that there are oil temperature has significantly influence the efficiency of the synthesized membrane separation performance. The fitted model was found to agree with the predicted and actual oil flux as well as separation efficiency which indicated by the high values of R² = 0.954 and R²_adj = 0.986. According to the optimized condition, the finding reported 4.71 % and 0.746 % average error for oil flux and separation efficiency which agrees with the forecasted and actual values. The novelty of this study lies in the development of an eco-friendly ceramic membrane derived from sugarcane bagasse waste, offering an innovative and sustainable solution for oily-wastewater treatment.</div></div>","PeriodicalId":100251,"journal":{"name":"Cleaner Chemical Engineering","volume":"11 ","pages":"Article 100151"},"PeriodicalIF":0.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143162094","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}

Biodiesel has emerged as a promising vehicular fuel due to its similar physiochemical properties to mineral diesel and its potential to minimise environmental impact. However, the commercialisation of biodiesel production faces challenges, particularly related to feedstock and catalyst selection. This study explored the utilisation of waste laboratory glass to synthesize heterogeneous catalyst for producing biodiesel from a blend of beef tallow and waste cooking oil. Heterogeneous catalysts are crucial for achieving high conversion efficiency, reusability, ease of separation and minimal environmental degradation. The particle size distribution of the catalysts was heterogeneous, with 23.33 % of particles passing 710 μm, 30.83 % passing 500 μm, and 45.83 % passing 350 μm. XRF analysis revealed that silica was the primary elemental constituent, comprising over 70 % of the total sample composition, and successful incorporation of Na, Mg, and Zn in the respective treated catalysts was observed. FTIR analysis of the calcined and uncalcined catalysts showed a sharp decrease in hydroxyl functional groups, indicating successful calcination.

Furthermore, the produced biodiesel was characterised to evaluate its fuel properties: the tested parameters kinematic viscosity, density, flash point and acid value were within the desirable limits for biodiesel according to American and European standards . Moreover, the catalyst showed that it can be reused as after six cycles of reuse a biodiesel yield above 89 % was realised.</div></div>","PeriodicalId":100251,"journal":{"name":"Cleaner Chemical Engineering","volume":"11 ","pages":"Article 100147"},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143162098","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 phenomena can be described by equilibrium models, which offer insight into adsorption capacity and thermodynamic properties, such as enthalpy and entropy variations, yet parameter uncertainty often undermines their accuracy. This study applies a Bayesian approach to assess uncertainties within adsorption models quantitatively and qualitatively. Through Bayesian analysis, substantial parameter variability was identified in the Sips model, with posterior distributions for thermodynamic parameters revealing broad uncertainty regions and a high likelihood of exothermic enthalpy values (i.e. <span><math><mrow><mi>P</mi><mo>(</mo><mrow><mstyle><mi>Δ</mi></mstyle><msup><mi>H</mi><mo>∘</mo></msup><mo>&lt;</mo><mn>0</mn></mrow><mo>)</mo><mo>&gt;</mo><mn>0.5</mn></mrow></math></span>), which often deviate from established thermodynamic expectations across different systems. Despite achieving good fit statistics (e.g., R² ≈ 0.99), this flexibility in the Sips model does not consistently translate into reliable thermodynamic interpretations. In contrast, the Langmuir model yields more stable estimates, offering narrower and thermodynamically consistent probability distributions for equilibrium constants (e.g., ΔH° &gt; 0 and ΔS° &gt; 0) and Gibbs free energy changes across temperature variations, albeit with slightly lower fit statistics (e.g., R² ≈ 0.97). These findings highlight the need for uncertainty analysis in model selection and advise caution in attributing physical significance to isotherm-derived parameters.

A response surface methodology (RSM) technique, based on a rotatable central composite design (RCCD), optimizes the transesterification reaction.

The optimal biodiesel yield from RSM is 86.76 % at optimized conditions. In comparison, the GA-BO hybrid approach results in a higher biodiesel yield of 96.45 %, at modified conditions. Experimental validation of the GA-BO approach further confirms a biodiesel yield of 96.67 %, with fuel properties meeting international biofuel standards.

Phosphorus recovery pathways include enhanced biological phosphorus removal, biologically induced precipitation as hydroxylapatite (Ca₅(PO₄)₃(OH)), and struvite (MgNH₄PO₄·6H₂O) formation.
