Progress and prospect of the preparation of manufactured soil from solid waste

Solid waste is a byproduct generated during the process of economic and social development, possessing both polluting and resource properties. Proper handling and disposal of solid waste are crucial steps toward achieving green development in society. Utilizing solid waste as a resource can save substantial resources and has synergistic effects on promoting social construction, developing a circular economy, and achieving the carbon peaking and carbon neutrality goals. This article starts with the technical requirements for the resource utilization of solid waste in China, reviews the current situation of the generation, treatment, and disposal of general industrial solid waste in China, and summarizes the typical characteristics and resource utilization pathways of such waste. It also examines the current state of research on the resource utilization of solid waste through manufactured soil technology. The article summarizes the preparation techniques and application scenarios of manufactured soils and reviews the ecological and environmental effects of manufactured soils prepared from solid waste. Finally, it looks forward to future technological breakthroughs in preparing manufactured soils from solid waste.
