Global waste management issues pose a considerable obstacle to achieving sustainability in today’s environmental challenges. This chapter provides comprehensive research data for an integrated waste management (IWM) system pertaining to future needs, exploring various techniques to control and dispose of municipal solid and liquid trash, agricultural waste, biomass waste, industrial hazardous and non-hazardous waste, and e-waste. The current chapter has insight into the present and future prospects of sustainable development of the environment, zero waste management, promoting reuse, recycling, and upcycling, improving treatment processes, reducing pollution, and implementing IoT-enabled approaches. Waste management techniques vary significantly at both national and international levels, with distinct methodologies employed according to various local needs. However, it provides a full assessment of the challenges of effective, enviro-friendly restoration of waste and the possibility of transforming it into valuable products. These impediments include inadequate infrastructure, limited resources, and insufficient legal frameworks. On the other hand, technical advancements such as intelligent waste collection systems, the use of biodegradable polymers, and bioenergy from organic waste contribute to effective waste management. Collaboration among all stakeholders, such as governments, businesses, academic institutions, and civil society organizations, is required for significant outcomes. Researchers, environmentalists, legislators, and professionals are making untired efforts to enhance generation restoration, promote the circular economy, and foster a sustainable future.
