This book describes about Lithium has become an indispensable part of the modern electronic world, due to the rapid advancement in the energy storage solution. However, its extraction, uses, and recycling create a huge environmental solution damaging human health and the environment. The primary purpose of writing this book is to provide a comprehensive thoughtful understanding of sustainable lithium management through bio-circularity to minimize energy investment and waste generation. This book aims to address the main sources, transport, and impact of LIB pollution in different ecosystems. It also highlights the challenges faced during lithium recycling, and sustainability, which leads to loss of precious metals. This book offers insight and knowledge into the mechanism of microbial bioleaching approaches and biotechnological innovation in bioleaching to maximize the efficiency of bioleaching. The main part of the book will also cover the innovative approaches to lithium bio-circular economy principles to promote green sustainable lithium recovery. By exploring the microbial bioleaching technology aligned with the bio-circular economy lithium can be efficiently recovered from secondary resources known as urban mines. This book also provides the policy framework, and technology innovation for the industry sector to follow closed-loop bio-circular economy approaches, ensuring resource efficiency for the long-term run. It also bridges the knowledge gap between research and industry by facilitating the case study example of real-world applications. This book will open a new world of lithium recycling where the microbial leaching technology aligned with bio-circular economy principles enhances the recycling process, reducing environmental impact and ensuring sustainable energy transition
