ことを目的としている。Even such disposable sanitary articles are required to be sanitary for the purpose of use, and are only discarded in the manufacturing process and discarded and incinerated. Even though the amount is small as a whole, the total amount is large, so that the amount to be incinerated is not negligible but a problem. Such sanitary articles are required to be sanitary, and are therefore difficult to regenerate. Even so far, renewal has not been talked about. In particular,
The so-called used diapers after use are stained with stool and urine, and the treatment is performed exclusively by incineration. The amount of used disposable diapers is enormous, and the disposal cost of used disposable diapers is, for example, 100 to 160 per kg.
Because it is a yen, it is a very large sum and is considered a problem. Moreover, incineration requires a large amount of fuel and a large amount of manpower, which is a problem. An object of the present invention is to solve the problems related to the reprocessing of such dirty sanitary articles.

The material of the sanitary ware is cleaned and sterilized by the stirring treatment in the disinfectant solution. In order to separate the material of the sanitary ware thus treated, the disinfectant solution in which the material of the sanitary ware is suspended is sent to a sieve having an opening of, for example, 0.1 to 1 mm. Due to the stirring treatment in the disinfectant solution, most of the water-soluble dirt and solid dirt adhering to the pulverized hygiene articles are
Because it will be dissolved or suspended in the disinfectant solution,
By separating with a sieve or filter medium having an opening of 0.1 to 1 mm, most of the water-soluble dirt and solid dirt adhering to the sanitary goods will be contained under the sieve or in the filtrate, and will be filtered on the sieve or filtered. Separated from residual sanitary products. The material of the sanitary product thus separated is washed with stirring in another disinfectant solution. Such repeated treatment in the disinfectant solution significantly reduces the number of bacteria remaining in the material of the sanitary article.
