This book chapter discusses the management of hazardous waste in developing countries, with particular emphasis on industrial hazardous waste, medical waste, and household hazardous waste. It seeks to identify the current situation and also aims to provide a review of the existing strategies that are particularly related to hazardous waste management. In developing countries, hazardous waste management systems lack a systematic approach to administer waste management programmes inability to effectively collect and manage wastes as well as to reduce the negative impacts of those activities. The current regulatory frameworks and regulations do not adequately address hazardous waste treatment and final disposal. There are inadequacies in the implementation of regulations associated with hazardous waste management due to fragmented responsibilities among government departments and local authorities. The chapter provides practical best processes for the management of hazardous waste aimed at improving the current situation.
