Abstract: The landfill mining and resource utilization of recyclable land resources，harmless and recycling of mineralized waste in landfill has significant economic and social benefits. The pain points in landfill management at home and abroad were comprehensively reviewed, with a keen focus on analyzing exemplar landfill treatment projects. It underscored the vital importance of pre-mining research, such as encompassing assessments of raw material recovery potential, economic viability evaluation and life cycle assessment. Based on the concept of comprehensive resource utilization of mineralized waste,the physical characteristics, heavy metal content, calorific value, and nutrient components of the mineralized waste in landfills were mainly described. Moreover, the mature resource utilization scheme was summarized, including humus reclamation technology and the thermal treatment of combustible components, thereby offering insights for the construction, excavation, and resource-efficient exploitation of large-scale landfills.
