Current problem of odors occurred in the portable toilet and its counter measure in future

Abstract

In recent years, train station toilets, toilets in public facilities and even home toilets have become more comfortable spaces. However, while permanent toilet spaces are becoming more comfortable, cost and usage conditions cause difficulties for portable toilets such as those used during disasters, construction and events.

This paper explains structural aspects of portable toilets as well as measures against odors.

Portable toilets were installed after the Kumamoto earthquakes last year and are indispensable in times of disaster. Our aim in this paper is to contribute to measures against odors in portable toilets during disasters.
