Research Abstract

The processing of the excretion-treatment in home care and the reduction and simplification of waste treatments are important subjects for the mitigation of physical and mental loads caused by the excretion both for care receivers and care givers, the maintenance of clean and sanitary life. In this research, to settle these problems, the establishment of excretion-treatment systems in home care and the development of excretion-solidification methods were examined.
The research on the realities of the environmental pollution caused by the excretion treatments and the physical and mental loads for care givers revealed the clothes-contamination and infection by excretion-treatment, the expense of excretion treatment. Furthermore, the skin troubles, such as feeling itchy rash, skin-peeling, and skin injury, of care receivers by using disposable diapers are the most important affairs. The grasp of the excretion pattern of care receivers, the proper use of disposable diapers should be most effective for the reduction of excretion pollution.
Next, to examine the excretion-solidification methods, the coagulation of proteins by tannin compounds was examined. Persimmon, mimosa and myrobalan tannins have higher abilities to coagulate proteins. Cellulose immobilized with these tannins have an excellent ability to absorb proteins. These results indicated that tannins, having variable abilities, such as protein-coagulation, anti-oxidant, anti-bacterial, water reserve and smell removing, are effective to use for disposable diapers. On the other hand, oligo-saccharides of glucose and glucosamin indicated higher anti-oxidant abilities. These results were reported at the 87th Annual Meeting of the Chemical Society of Japan (2007), and published on the Journal of Radioanalytical and Nuclear Chemistry, 272 (2) 251-255 (2007), and the World Journal of Microbiology and Biotechnology, on-line publishing (2007).
