Currently production of machine-washable wool utilizes polluting chemicals, which greatly harm the environment. Herein, an alkaline protease (AP) from soil-derived strains was isolated, characterized, purified, and stabilized. A total of 480 protease-producing strains were screened, and strain SH244 was identified as <em>Bacillus amyloliquefaciens</em> via 16S rDNA sequencing. The alkaline protease SH244-AP was purified using ammonium sulfate precipitation and ion exchange chromatography, achieving a 51.94-fold purification with a 29.8 % yield. The enzyme exhibited optimal activity at 55 °C and pH 10, with enhanced thermal stability in the presence of Ca²⁺. It showed remarkable tolerance to surfactant (e.g., Tween-20, Triton-X100) and H₂O₂. These properties suggest potential applications in textile wet processing, such as felt-proofing of wool. By virtue of its tolerance against H₂O₂, some metal ions, and nonionic detergents, the isolated AP, along with H₂O₂, was used in a water- and energy-saving eco-friendly simultaneous bleaching and felt-proofing of wool. The alteration in the chemical structure of wool was monitored by amino acid analysis, alkali and urea-bisulfite solubility, and base combining capacity of the treated fibers. The effect of bio-treatment of wool with the aforementioned AP on its surface morphology, weight, degree of whiteness, tensile strength and elongation at break was evaluated. The study's results demonstrated that the proposed process can produce machine-washable wool without significant weight and tenacity losses.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"49 ","pages":"Article 102269"},"PeriodicalIF":5.8,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145610509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accelerated carbonation has emerged as a promising method owing to its sustainability advantages. A novel flow-through agitated carbonation method was developed to enhance the early-age reactivity of bottom ash. The results show that agitation during carbonation promotes CaCO₃ crystal growth along the (104) primary crystal plane, increasing the proportion of thermodynamically more stable CaCO₃ (Ⅰ) crystals among newly formed CaCO₃ to over 30 %. In addition, the crystal size decreases and the morphology becomes more spherical, facilitating the formation of stable nucleation sites that accelerate cement hydration, particularly during the acceleration and deceleration stages. Carbonated BA also provides significantly higher lubrication compared with OPC particles, resulting in a 36 % improvement in paste flowability at a 50 % replacement ratio. Compared with conventional activation strategies, BA treated via agitated carbonation exhibits a pronounced strength enhancement in blended cement, driven by the synergistic effects of nucleation and particle-filling. For example, at a water-to-binder ratio of 0.4 and a 15 % replacement level, the 3-day compressive strength exceeds 30 MPa. Overall, carbonation transforms bottom ash from a low-reactivity residue into a value-added SCM, achieving 15–25 % lower GWP per MPa and 10–15 % lower cost per MPa than OPC while maintaining superior mechanical efficiency. The findings demonstrate a viable pathway for valorizing alkaline solid waste through CO₂ utilization and provide mechanistic insights for developing sustainable cementitious materials.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"48 ","pages":"Article 102263"},"PeriodicalIF":5.8,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145576302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study includes household food waste data from 282 voluntary households in 2021. Data was collected by following a diary-supported direct food waste measurement methodology (FUSIONS methodology), completed by pre- and post-study questionnaire surveys with one respondent from each household. Avoidable (edible) food waste dropped by 23.99 % (from 33.14 kg/capita/year to 25.19 kg/capita/year) between 2016 and 2021. The reduction of total FW was only 3.73 % (68.04 kg/capita/year in 2016 and 65.50 kg/capita/year in 2021). Possibilities for further FW reduction in Hungarian households were investigated. This study found that 84 % of the households underestimated their actual total FW generation, and the average level of underestimation was 48.5 %. Research data suggests that unavoidable FW is not perceived to be wastage by the respondents. According to post-study questionnaire results, 77 % of the respondents believe they can further reduce the FW in their households. The finding suggests that, despite the decrease in household food waste from 2016 to 2021, there is considerable potential for further reduction, especially in the avoidable category. This potential is in line with broader goals of reducing food waste in households, contributing to national and EU targets for sustainable resource management and food waste reduction.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"48 ","pages":"Article 102209"},"PeriodicalIF":5.8,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145576301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response to the global imperative to transition from unsustainable energy systems, the research introduces a novel integration of Hesitant Fuzzy Linguistic (HFL) Term Sets with the Simple Additive Weighting (SAW) method (HFL-SAW) to rigorously derive weights for a comprehensive set of criteria and sub-criteria essential to renewable energy selection. Building on this methodological foundation, the study employs three robust MCDM techniques, HFL Additive Ratio ASsessment (ARAS), HFL Multi-Attributive Border Approximation Area Comparison (MABAC), and HFL Evaluation based on Distance from Average Solution (EDAS), to comprehensively evaluate and rank competing renewable energy alternatives. This dual-level novelty which are methodological innovation and application to Turkey's evolving energy landscape distinguishes the study from prior research. The numerical results indicate that, based on the factor weights derived from HFL-SAW, SDG6 (Clean Water and Sanitation), SDG7 (Affordable and Clean Energy), and SDG13 (Climate Action) emerge as the most pivotal, underscoring the intrinsic interdependence between water security, sustainable energy production, and climate change mitigation. Comparative ranking thus reveals some variability among the methods, with hydropower energy systems consistently achieving superior rankings in both the HFL ARAS and HFL MABAC evaluations, and bioenergy and biomass systems are predominantly favored in the HFL EDAS assessment. The convergence of these findings not only substantiates the robustness and validity of the integrated analytical approach but also highlights the potential efficacy of hydropower and bioenergy solutions in facilitating Turkey's strategic energy transition.
