Currently, it is a serious concern to manage waste in the environment. Therefore, detailed knowledge of heavy metals, their eco-toxicological and health effects and ecofriendly approaches for their immobilization and detoxification is urgently required to control and minimize the environmental pollution. Composting is one of the popular methods in waste management and there are a lot of issues pertaining to composting. One of it is the leaching of heavy metals. This book discusses thoroughly, the availability, leachability and the speciation of heavy metals in the entire process of composting.
