    Green Chemistry Approaches to Environmental Sustainability: Status, Challenges and Prospective
    (Elsevier, 2023-09-29T00:00:00) Garg, Vinod Kumar; Yadav, Anoop; Mohan, Chandra; Yadav, Sushma; Kumari, Neeraj
    Green Chemistry Approaches to Environmental Sustainability: Status, Challenges and Prospective provides a comprehensive and complete overview of the emerging discipline of green chemistry and fundamental chemical principles. The book bridges the gap between research and industry by offering a systematic overview of current available sustainable materials and related information on new materials' suitability and potential for given projects. Along the way, the book examines natural and biodegradable materials while also presenting materials with multifunctional properties. Topics addressed in this book will be major accomplishments for sustainable developments in biofuels, renewable energies, and in the remediation of pollutants in water, air and soil. � 2024 Elsevier Inc.

    Introduction to environmental and green chemistry
    (Elsevier, 2023-09-29T00:00:00) Yadav, Sushma; Yadav, Anoop; Mohan, Chandra; Garg, Vinod Kumar; Kumari, Neeraj
    Both environmental chemistry and green chemistry are important and have a crucial role in the ecosystem; however environmental chemistry discusses about the environmental problems, while green chemistry provides the solution. Green chemistry is new emerging area that strives to achieve the sustainability at the molecular level. Green chemistry generally deals with reduction or minimizing the harmful and toxic chemical products with eco-friendly one. From the past few decades, green chemistry has received a remarkable attention of the researchers due to its ability to achieve environmental and economic goals by doing chemical invention. Through different major modification of green chemistry including renewable feedstocks, biocatalysts, green solvents, dual aims of environmental protection and economic benefits could be achieved. This chapter generally covers the concept of origin of environmental and green chemistry with a cohesive set of 12 principles. � 2024 Elsevier Inc. All rights reserved.

    Management of banana crop waste biomass using vermicomposting technology
    (Elsevier Ltd, 2021-01-20T00:00:00) Mago, Monika; Yadav, Anoop; Gupta, Renuka; Garg, V.K.
    This study reports the vermicomposting of banana crop waste biomass by Eisenia fetida. Cow dung has been used as bulking agent in this study. The experiment was conducted in six vermireactors containing different ratios of banana leaf waste biomass (BL) and cow dung (CD) for 105 days. Earthworm activity significantly reduced pH, TOC, C:N and C:P ratio of the wastes. Whereas macronutrients and micronutrients content increased after vermicomposting. TOC content of wastes reduced by 40�64% and C:N ratio of the vermicomposts was in the range of 8.9�24.3. The benefit ratio for heavy metals (Cu, Fe, Zn, Cd, Pb, Mn and Cr) was in the range of 0.23�3.44. The results indicated that the growth and fecundity of the earthworms was best in the vermireactors having 20�40% BL. Finally, it was concluded that vermicomposting can be included in the overall scheme of banana crop waste management. � 2021 Elsevier Ltd

    Microplastics in multimedia environment: A systematic review on its fate, transport, quantification, health risk, and remedial measures
    (Elsevier B.V., 2023-01-06T00:00:00) Rose, Pawan Kumar; Jain, Monika; Kataria, Navish; Sahoo, Prafulla Kumar; Garg, Vinod Kumar; Yadav, Anoop
    The ever-increasing presence of microplastics in many environmental components has been a cause of worry for humanity due to their small size and potential health risk. Since the last decade, numerous studies have been conducted on the prevalence and dispersion of microplastics. However, at present, there aren't any systematic studies on fate and transport of microplastics that consider multimedia environmental systems and their mitigation measures. Also, there are limited studies on the routes through which humans are exposed to microplastics. In this review, about 380 articles were evaluated to uncover the extent of microplastic fate, transport, and pollution in different environmental components, including soil, freshwater, marine, and atmosphere, as well as its effect on different ecosystems. We gave special attention to understanding many routes and sources of microplastics intended for human consumption and their consequences on human health. Furthermore, we tried to emphasize on the different methods used for sampling, extraction, identification and characterization of microplastics, along with associated benefits and limitations. This study highlighted existing knowledge and gaps in the remediation of microplastics. On this basis, the bottleneck and current challenges have been proposed. � 2023 Elsevier B.V.

    Sustainable treatment and nutrient recovery from leafy waste through vermicomposting
    (Elsevier Ltd, 2021-11-22T00:00:00) Mago, Monika; Gupta, Renuka; Yadav, Anoop; Kumar Garg, Vinod
    The present investigation was carried out to evaluate the vermicomposting potential of two cruciferous vegetables' residual biomasses under laboratory conditions. Cabbage and cauliflower residual biomasses were spiked with 60% cow dung and vermicomposted for 90 days. The results showed a decrease in pH (5.3�9.8%), Total Organic Carbon (36.7�42.8%); increase in Electrical Conductivity (33�99.4%) and ash content (144.7�187.8%) after vermicomposting. Significant reduction in C:N ratio (49.5�76.4%) and C:P ratio (62.8�66.04%), increase in Total Kjeldahl Nitrogen (49.3�85.3%), Total Available Phosphorus (68.2�98.1%), Total Potassium (91.8�120.3%) were observed. FT-IR spectra of the vermicomposts had lesser band heights and peak intensities than raw materials. This evidenced decomposition of organic compounds and vermicompost stability. Germination Index values was calculated to determine the phytotoxicity level. Earthworms' growth and prolificacy was evaluated in terms of biomass gain, cocoons production and worm growth rate. Finally, it was inferred that cruciferous vegetables' biomass can be used for vermicomposting. The cauliflower residual biomass has shown better decomposition efficiency than cabbage residual biomass. � 2021 Elsevier Ltd
