Cement production hurts the environment as its an energy-consume process that generates a considerable amount of carbon footprint, This influences water purity, vegetation vitality, and neighboring communities' well-being, causing environmental degradation; industrial operations added to air, water, and noise pollution intensify climate change and ecological imbalances. This study investigates the potential of incorporating waste glass into concrete to improve its mechanical properties and address environmental concerns. It examines the effects of different chemical compositions of glass powder on predicted outputs, such as compressive strength and splitting tensile strength. Factors including water-to-binder ratio, cement content, and glass powder replacement percentages are analyzed across various ranges. The study evaluates the impact of Al₂O₃ and Fe₂O₃ content in glass powder and considers parameters such as fine aggregate, coarse aggregate, superplasticizers, and curing time. Results show a gradual reduction in compressive strength with an increasing Al₂O₃/Fe₂O₃ ratio while splitting tensile strength increases. Based on compressive strength measurements, a correlation model was developed to predict flexural strength. Multiple variables models were employed for output prediction, and various criteria were used to assess model performance.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"44 ","pages":"Article 101968"},"PeriodicalIF":5.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534439","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}

Wheat bran, one of the most popular by-products of the milling industry, owing to its ample supply and cost-effectiveness, finds its primary application in animal feed and human consumption. Leveraging this material in various ways, not only reduces the amount of waste, but also promotes a circular economic model, allowing the preparation of value-added products, including enzymes. The present study demonstrates the potential of wheat bran's as a substrate for producing a \"green-enzyme\" mix through solid-state fermentation (SsF). On the second day of the SsF, cellulase activity (FPase) exhibited a notable value, exceeding 25 FPU/g_ds, accompanied by endoglucanase (CMCase) values that greatly exceeded 140 U/g_ds and glucoamylases over 60 U/g_ds on day 6. A hydrolysis test on wheat bran showcases an increase in TRS by over 280% after 48 h. Further, the effect of different enzyme extraction procedures and storage conditions on the enzyme activity was studied. FPase and CMCase exhibited high stability when extracted with sodium citrate buffer and freeze-dried. In contrast, glucoamylase extracted with water retained activity under the same conditions. In addition, enzyme immobilization in a silanic matrix resulted in highly stable preparates: a weight loss of only 13.18% at 407.69 °C and a mere 19.38% loss at 734.56 °C was observed. SsF used for <em>in situ</em> enzyme production is an accessible and cost-effective process. The process possesses ecological and sustainable characteristics and can be easily integrated into various biotechnological processes.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"44 ","pages":"Article 101974"},"PeriodicalIF":5.5,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both microwave-assisted and low-temperature hydrothermal synthetic methods of metal phosphonates prove to improve both time and energy efficiency. The obtained results from both potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) analysis show that after an hour of immersion, the corrosion inhibition efficiency (IE) was 38.98% for CoPA, 40.54% for CuPA and NiPA, and 62.97% for PA. The IE for PA dropped to around 40% as immersion time increased, indicating the development of a porous, weakly adsorbed coating that permits aggressive ions to reach the metal surface. Following 21 days of immersion, the IE for NiPA and CoPA considerably increased to roughly 92.5%, suggesting that a stable, compact protective layer had formed on the metal surface. The shifting of Tafel slopes suggests that both blocking and energy impacts continue to influence the inhibitory action. These results show that metal phosphonates, mainly CoPA and NiPA, work as mixed-type inhibitors, slowing down both the cathodic and anodic processes that cause corrosion. The electrochemical impedance spectroscopy sustains the potentiodynamic data. Quantum chemical calculations explored the relationship between the molecular configuration of MePA and its inhibition efficiencies.

Estimated 3–5% of this amount ends up in the environment, where it poses significant threats to ecosystems and biodiversity. Littering, a growing global challenge, requires a combination approach to tackle its causes and mitigate its impact. There are different strategies to combat littering. Plastic waste is a complex subject needing a combination approach to deal with the current littering problem by supporting adequate waste infrastructures especially in developing countries. Consumer behavior and awareness must also be addressed. But even with immediate and concerted action to reduce consumption, more than 700 million tonnes of plastic waste will cumulatively enter the aquatic and terrestrial ecosystems until 2040. Waste management systems, even if improved, do not have sufficient capacity at the global level to cope with the huge mass of plastics entering the environment. Especially for plastic, which will foreseeable and inevitably enter the environment, where it can persist for hundreds of years (‘forever’ plastics), a solution is needed. Biodegradable plastics, that meet the criteria of ‘Safe and Sustainable by Design’ (SSbD), offer innovation perspectives and can be a complementary strategy to tackle the marine litter problem. ‘Safe and Sustainable by Design’ is a holistic framework for developing chemicals, materials, and products that prioritizes safety and sustainability at every stage of their lifecycle.
