Description

In order to be prepared for natural disasters and develop an effective self-sufficient emergency body waste management system, the author devised a personal emergency toilet that uses disposable diapers that are readily available on the market and tested it under various conditions. <br>  The addition of 200 cm3 of wood pellets sold as cat litter to each toilet unit was found to be effective in preventing the toilet from producing ammonia gas and emitting a foul smell. An oxygen-based bleaching agent for clothes was not very effective in preventing them, especially during the hot summer season. Spraying the toilet about six times with the agent after use was found to be the most effective. This disposable diaper-based personal toilet is cheaper than ordinary emergency toilets on the market, and the materials are easily available. Based on the results, the author proposes adopting disposable diaper-based personal toilets to prepare for natural disasters.
