After being screened and sorted by garbage treatment equipment, the aged garbage buried in the landfill is classified and recycled for resource recycling, achieving harmless treatment, reduction, and resource recycling of the buried aged garbage. At the same time, it can also handle issues such as leachate leakage and surface water pollution. The entire process will not cause further pollution, leading to sustainable development of the environment.

After being sorted by garbage treatment equipment, the buried stale garbage has achieved the recycling and reuse of waste resources, with a certain return on economic resources. Overall, the cost and benefit of the project are relatively reasonable and effective, and the government only needs appropriate economic subsidies. At the same time, sorting and processing waste, clearing landfills, and further processing land resources as needed for reuse have significant economic benefits.
