In India, industrialization and urbanization also significantly release these contaminants, exacerbating environmental pollution and posing risks to human health and ecosystems. Global emerging pollutants are increasingly concerning due to their persistence and potential adverse impacts. Understanding the toxicity and fate of these substances is essential for developing effective remediation strategies, given their complex transformations in environmental contexts. Remediation is challenging because contaminants possess varied characteristics and are widely dispersed, but innovative technologies like advanced oxidation processes, phytoremediation, and membrane filtration offer promising solutions.

In addition, plastics are derived from non-renewable fossil resources, and their growing demand is also partly responsible for greenhouse gas emissions and climate change. The aim of this paper is to explore the potential of plastic waste as a material resource, and thermocatalytic pyrolysis as a recycling process, to produce aliphatic and aromatic hydrocarbons, which are important chemical intermediates for various industries. We show that plastic pyrolysis can achieve a high yield of liquid hydrocarbons (~ 80%) with a suitable distribution of aliphatic and aromatic compounds, by using different pyrolysis conditions and a catalyst. Specifically, this paper demonstrates the possibility of deriving two key classes of hydrocarbons, i.e., aliphatic (C10–C20 hydrocarbons) and aromatic hydrocarbons (xylene, toluene and benzene derivatives) with a yield of ~ 80% liquid hydrocarbons via catalytic pyrolysis. We also briefly discuss the challenges and opportunities, and the environmental and economic implications.</p></div>","PeriodicalId":675,"journal":{"name":"Journal of the Indian Institute of Science","volume":"104 2","pages":"383 - 394"},"PeriodicalIF":1.8,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These vital ecosystems sustain ecological processes to provide services such as nutrient cycling, water purification, reducing pollution, carbon sequestration, groundwater recharge, provision of fish, fodder, fuel, and water, flood reduction, erosion control, aquatic biota habitats, education opportunities, aesthetics, and recreation. However, due to globalization, these fragile ecosystems are vulnerable to unplanned developmental activities and rapid urbanization, leading to large-scale land cover changes and hydrologic regimes. The sustained inflow of untreated wastewater (from the industrial and domestic sectors) into wetlands has altered the chemical integrity, which necessitates inventorying, mapping, and regular wetland monitoring to evolve conservation strategies. Integrating spatial and non-spatial data, analysis, and visualization with decision models through decision support systems enables informed decisions. In this context, the Bangalore Lake Information System (BLIS) is designed with information on water quality, biodiversity (microalgae, zooplankton, ichthyofauna, macrophytes, and birds), threats (encroachments, inflow of untreated sewage, etc.) and ecosystem services of lakes in Bangalore, Karnataka State, India. Rapid large-scale land use changes have resulted in an alteration in the hydrologic regime, the loss of habitats, and the disappearance of native species. BLIS empowers decision-making through knowledge of lake distribution in terms of the physical, chemical, and biological aspects and the value of ecosystem services, which is crucial for evolving strategies for prudent management of water bodies in Greater Bangalore.</p></div>","PeriodicalId":675,"journal":{"name":"Journal of the Indian Institute of Science","volume":"104 2","pages":"415 - 434"},"PeriodicalIF":1.8,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142889606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, thorough toxicological assessments are crucial to verify the effectiveness of each technology and prevent the generation of new PFAS or toxic byproducts during treatment. Currently, there exists a pressing societal demand exists to explore affordable and environmentally safe PFAS degradation technologies, minimizing negative environmental repercussions, and being feasible for large-scale field applications.

In the context of dumpsite mining, the study examines the potential recoverable fractions, challenges in recyclability and processing, and the economic aspects of mining operations.

Additionally, case studies are reviewed to demonstrate the successful application of dumpsite remediation for environmental protection and containment, as well as the potential of mining to generate value-added products within a circular economy perspective. However, challenges observed in the case studies, such as heterogeneous waste composition, technological limitations, and economic viability, present significant barriers.

Consequently, exploring substitutes for fossil fuels and renewable raw materials in the production of sustainable fuels has become a critical area of research. Over the past decades, significant efforts have been dedicated to researching renewable and eco-friendly fuels from diverse sources. A prominent avenue of investigation involves biodiesel production from fats and oils through the uncomplicated process of transesterification, utilizing acid–base catalysts. The design of these catalysts is pivotal, not only for ensuring efficient conversion but also for achieving high biodiesel selectivity and enhancing the techno-economics of the process. Strategic selection of raw materials, such as non-edible fats and oils, is crucial to elevate the process's importance and mitigate potential conflicts between food and fuel resources. Furthermore, catalyst design and synthesis play a crucial role in refining the biodiesel production process. Particularly, catalysts derived from waste, featuring precise active sites, are recognized as important tools for achieving enhanced catalyst activity at reduced costs. Therefore, this review examines the trajectory of catalyst development for biodiesel production from various feedstocks, with a primary focus on the design of waste-derived catalytic nanostructured materials for sustainable development. It is anticipated that this review will provide insights into the next generation of sustainable biodiesel production methods.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":675,"journal":{"name":"Journal of the Indian Institute of Science","volume":"104 4","pages":"841 - 868"},"PeriodicalIF":2.3,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
