We are showcasing our two sanitation projects at the Gates Foundation Toilet Fair in New Delhi.
Here are the links for two videos on the projects:
and below are pictures of our Anaerobic Digestion Pasteurization Latrine (ADPL) system. The biogas-powered heat sterilization systems are simple and cheap. On the right of the picture (green vessel) is an anaerobic digester (here connceted to an eToilet from ERAM Scientific). The heat sterilization system pasteurizes the effluent from the digester. The system is very energy efficient, and enough biogas is produced in the digester to keep the effluent above 70 C, thereby killing all pathogens.
