In densely populated large cities, waste disposal is a headache problem. It is common practice to collect and send the waste to a landfill for landfill treatment or incinerate the waste with an incinerator. Both create environmental protection issues and termination of overconsumption can further mitigate landfill saturation. Disposal of waste in landfill sites not only contaminates ground water and gives off odors, but also makes less and less area available for landfill in many cities. Incineration inevitably produces toxic gases, which harm organisms. Most cities are researching ways to reduce the production of garbage and encouraging resource reclamation.
In the existing municipal solid waste sorting process, large materials are sorted out by manual selection, and entanglements are basically not sorted and remain in a waste sorting line.
