Gates Foundation Toilet Fair in New Delhi

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.

Derek Chitwood Visits Lab

Derek Chitwood visiting labOld friend visiting: Derek Chitwood, postdoc in Deshusses' lab in around 2000 made a quick stop at Duke at the occasion of UNC's Conference on Water and Health. Derek now heads an NGO in Southwest China. They make simple clay/ceramic filters that provides safe drinking water. Marc and Derek are holding a simple heater/heat exchange built in Kenya (see Aaron's project below)

Aaron Forbis-Stokes (PhD student in Deshusses lab) is spending the summer in Eldoret Kenya to deploy our anaerobic digester - biogas powered heat/heat recovery pasteurization system for safe sanitation system in the field.

Deshusses Awarded Grant from Bill and Melinda Gates Foundation

before and after treatmentThe Bill and Melinda Gates Foundation has awarded a Reinvent the Toilet Challenge grant to a team led by Dr. Deshusses! We will be using supercritical water oxidation to convert sewage to harmless byproducts and clean water with minimal or no energy input (see picture below of before and after treatment).
