Kao and Kyoto University, major chemical manufacturers, started a demonstration experiment in Saijo City, Ehime Prefecture in January to establish a carbonized recycling system for used paper diapers.With the aim of contributing to the reduction of carbon dioxide emissions by converting used disposable diapers into carbon materials, we are planning to implement a recycling system in society after 1.
According to Kao, Kao and Kyoto University will develop a device to carbonize used disposable diapers before collection.The device is characterized by reducing the volume while sterilizing and deodorizing used disposable diapers by carbonizing them efficiently in a short time by a low temperature reaction.
For the time being, after confirming on-site issues such as the amount of garbage and the amount of work generated at the nursing care facility in Saijo City, we will install it in the nursery facility in Saijo City after April when the equipment is finished and collect the used disposable diapers by carbonizing them. do.Since the volume will be significantly reduced, the collection frequency is expected to be once or twice a month.
The collected used disposable diapers will be used to promote the growth of plants in the gardens of childcare facilities, and research will be carried out with the aim of converting them to other carbon materials such as activated carbon.
A large amount of used disposable diapers are discharged as garbage in childcare facilities, long-term care facilities, hospitals, etc., but after collection, they were incinerated and carbon dioxide was emitted.Kao hopes that it will help reduce carbon dioxide emissions and reduce the burden on caregivers, childcare workers, and parents.The findings obtained from this demonstration experiment will be applied not only in Japan but also in Southeast Asia, where the waste problem is becoming more serious, and will be useful for problem solving.
