The book describes hazardous waste industries, sources of waste generation, characterization and treatment processes/ methods and technique and technology to deal with the treated waste as per the prescribed standard. Advanced treatment based on the microbial remediation, plant-based decontamination, rhizoremediation and nano-based remediation is also explained. Advances in treatment technology using biotechnological tools/bionanotechnology for removal of contaminants are described. This volume will help readers to develop biotechnological and nanotechnological approaches for the remediation of hazardous waste and the developed technology that can be transferred from laboratory to land andpiloting to commercial scenarios.
