"Chrome Sludge Converted to Vermicompost Earthworm Diversity" written by R. HajiraBanu is a comprehensive book that explores the process of converting chrome tannery sludge into vermicompost using two types of earthworms, the exotic EpigeicEudrilusEugeniae and the endemic AnecicLampitoMauritiiKinberg. The book investigates the impact of this process on the genetic diversity of these earthworms, shedding light on the potential benefits of vermicomposting as a sustainable waste management solution. The book delves into the process of vermicomposting and the role of earthworms in biologically breaking down the sludge into a nutrient-rich compost that can be used as a fertilizer. It examines the suitability of different types of earthworms for this process, and compares the efficiency and effectiveness of the exotic and endemic species in terms of vermicomposting performance and genetic diversity. Through detailed research and analysis, Banu provides insights into the potential environmental benefits of vermicomposting as a sustainable waste management solution. This book is a valuable resource for environmentalists, researchers, and waste management professionals seeking to explore the potential of vermicomposting in reducing the environmental impact of waste disposal while improving soil health and fertility.
