This study assesses the current ecological state of the hyper-eutrophic, warm polymictic Hauz Khas Lake in Delhi, India, which has been rejuvenated with Sewage Treatment Plant (STP) effluent and suffered from eutrophication since then. The primary objective was to evaluate the lake's health by analyzing major physical, chemical, and biological parameters and to quantify changes over an eight-year period. Water quality was assessed using the Water Quality Index (WQI) and Trophic State Index (TSI), with further statistical analysis conducted via Principal Component Analysis (PCA). Our findings reveal that the lake is under significant stress from elevated nutrient inputs (NO₃-N: 1.9–3.13 mg/L, PO₄³⁻: 4–8 mg/L), resulting in a hyper-eutrophic state of 191.66 ± 10.68 (2022–23). The WQI ranged from 44.28 to 64.28, indicating medium to poor water quality with a slight degradation compared to 2015 data. PCA results show a significant intensification of interactions among water quality parameters over the last eight years, with the variance explained by the first two principal components increasing by 37.5 % and 28.57 %, respectively. This study concludes that while the STP-based rejuvenation strategy has maintained the lake's physical existence, it has led to severe hyper-eutrophication, highlighting the urgent need for advanced nutrient management strategies for urban lake conservation</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"8 ","pages":"Article 100126"},"PeriodicalIF":0.0,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145266980","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}

Biofuels can be produced from plants, agriculture, domestic, industrial or several biological sources and their waste products. The most widely known biofuels are biodiesel, bioethanol, biobutanol, and biohydrogen. By turning them into useful and environmentally friendly products, the use of these biological products and their wastes to create biofuels also helps us manage waste. In recent years, waste from plants, algae, or microbes has been used to produce biofuels. It has recently come to light that certain oily fish or their waste can also be used to make biodiesel. Fish waste has a higher quantity than any other food waste, which makes it more suitable for energy production. Some latest studies have revealed that, the 93 % yield of biodiesel may be obtained through acid catalysed esterification and alkaline catalysed transesterification. Protocols must be established in order to produce effective biofuels from fish waste and achieve better outcomes. Fish waste conversion to biodiesel is a novel idea, and progress toward this goal is being hampered by a lack of understanding. As a result, the purpose of this article is to discuss the production of biofuels from fish waste, as well as the biological, physiological, and chemical factors involved. It will also aid understanding of biodiesel production at the commercial scale. Hence, this paper will help raise awareness of the value of using biofuels and improve the production of biodiesel.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"8 ","pages":"Article 100124"},"PeriodicalIF":0.0,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145266981","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}

Comparative metrics demonstrate that DMRS can reduce transportation costs by up to 70 %, lower emissions by 60–70 %, and enhance job creation and energy efficiency marking them as viable, scalable alternatives to centralized systems.
