Incinerating, disposable diapers

Another problem related to disposable diapers is disposal after use [18,20]. The weight of a disposable diaper for children is approximately 40 to 50 g, which increases to about 200 g after the use. The annual consumption of disposable diapers in the world is approximately 56 billion, which results in 11.2 million tons of waste. In Japan, the annual consumption is 4.6 billion diapers, which becomes 0.92 million tons of waste. In the Western countries, waste sanitary products are used for landfill whereas in Japan they are incinerated. In the case of landfill,... 

Considering that the final use of waste is in land reclamation, dissolution of incinerated ash and its content was measured and the results are shown in Table 19. This study reveals no problem with used disposable diapers. 

The risk of diarrheal iUness in daycare centers has been clearly linked with contamination of hands and items such as toys, so prevention of such contamination is an important step in controlling the spread of iUness in this setting. It should be noted here that, when thrown away in the mbbish, a soiled disposable diaper is typically wrapped tightly using the diaper tapes, thus providing additional containment of the feces until safely disposed off by incineration or in a landfill. In contrast, reusable cloth diapers must be retained and laundered, allowing many opportunities for contamination of hands, surfaces, or other aspects of the environment with fecal organisms. 

P G is working with converters and end users. This aspect of the value chain includes conversion of the formulated resins into initial forms, like films, fibers or molded articles, as well as secondary conversion into nonwovens, laminated packages and papers. End users then use these to make or package consumer or industrial produets, like diapers, hamburgers or computers. Finally, the produets are used and then eventually disposed of in one of several ways (eomposting, landfill, digestion, incineration) where the biocycle is completed.
