Environmental Sciences Europe volume 32, Article number: 107 (2020)
Apart from fulfilling the demand of society, the industrial sector, including paper, tannery, distillery, and textile, plays an essential role in manufacturing of the products while, such all still emitting hazardous contaminants to the environment during manufacturing operation. Significant contaminants, including PAHs, EDCs, Dyes, and POPs, are the primary ingredients of wastewater and sludge emitted from such industries. Such contaminants seem to have a carcinogenic, cytotoxic, and mutagenic toxicity endpoints. As a consequence, the long-term presence of such contaminants has led to severe environmental and human impacts. Therefore, it is necessary to tackle such issues to clean-up contaminants and to ensure environmental protection by reducing the toxicity of such contaminants. Here we review the book “Emerging and Eco-Friendly Approaches for Waste Management” for addressing waste management techniques in an eco-friendly manner. In this collection, different approaches, including specific unique plant-based methods for bioremediation, endophytes, and a specific number of micro-organisms, have been reported for decolorization of toxic textile dyes, along with biodegradation of different phenolic, chlorinated, lignin, and its derived compounds. Besides the conventional treatment techniques for clean-up of lignin, lignin-derived compounds, PAHs, chlorinated phenol compounds, EDCs, a certain number of methods in an eco-friendly manner are also explored for remediation, and mitigation of such pollutants using specific microbial oxidoreductase enzymatic systems. Highly potential oxidoreductase derived from different microbes, plants, have been summarized to minimize the toxic effects of various toxic compounds. The book, therefore, seems to provide insight through different recent and eco-friendly approaches for waste management and offers the opportunity to minimize, reduce the effects of contaminants, and thereby attempting to reduce toxicological endpoints to ensure the safety of the environment.

Algae are well-known to be widely distributed on earth and adapted to different habitats. The remarkable aspect of its rapid adaptation helps the algae to grow in a diverse variety of environmentally suited for wastewater treatment and production of biofuel and other value-added products, including food, feed, fertilizer, pharmaceuticals, and, biofuel, etc.
Few other modern trends, and the absence of these aspects (modern trends) for wastewater treatment, including in silico approaches, highlight a negative part of this book. However, it might be much excellent if all these elements were applied to it.
The present book could be better in a much deeper understanding of the mitigation of the environmental contaminants if a few chapters were added to it covering the in silico technologies or approaches. Computational or in silico methods are the emerging trends and widely being used in bioremediation. Molecular docking, molecular dynamics simulation, homology modeling, and biodegradation pathways prediction are the crucial techniques that are the lack in this book. Additionally, environment conservation and ethics in waste management also must be incorporated and updated in the next edition. Besides ignorance of these points, the above book may be suggested to a variety of professionals, scientists, students, researchers, etc. having interests in bioremediation technologies in an eco-friendly manner.
Moreover, this book further encourages the basic and specialized understanding of environmental issues among researchers, scientists, and academics engaged in microbiology, biotechnology, and environmental sciences. Readers may often obtain useful information/greater awareness about environmental aspects and remedies.
