With the improvement of living standards and the aggravation of aging

the use of disposable diapers has increased significantly

and has become the third largest domestic solid waste after kitchen waste and plastic. Therefore

the treatment and recycling of waste diapers is an important topic. Although there are some recycling cases of waste diapers in advanced countries

there are few papers on the recycling of waste diapers in China. Therefore

this paper introduces the present situation and the structure of waste diaper disposal

and summarizes the research progress in the field of waste diaper recycling

including overall recovery

simple disassembly recovery and complete separation recovery technology. Moreover

the potential applications of waste diaper disposal in fuel preparation by pyrolysis

mixed composting

soil quality improvement and catalyst preparation were also reviewed.
