The world’s highest dry toilet was recently installed at Saint-Gervais-Les-Bains in the French Alps at an altitude of 4630 meters. The manufacturer, Ecosphere Technologies, specializes in waterless, chemical-free dry toilets for locations that are rural or far from sewage systems. Their toilets use a worm-composting system. If you’d like to understand exactly how they work, watch this video.
I am a senior Civil/Envirnmental Engineer, working with the toilets since 1979, basically with dry toilet technology in Nepal
I am very much impressed with the DT in Alps in the altitude of 4630 metres, how you can install such toilets in the Everest , please proceed ahead
