Smart Toilet Saves Vital Health Data from Getting Flushed

Some of the most important information about our health comes from an unexpected and decidedly icky source. Our daily excreta (yes, the feces and urine we flush away every day) can actually tell us a lot about our health and help us monitor our bodies for disease. A Bass Connections Team is working [...]

Fecal Sludge Drying

Fecal sludge is persnickety, to say the least. Team member Katelyn Sellgren joined a panel of experts for a webinar to explore the difficulties researchers face in the drying of fecal sludge and to discuss potential solutions to these challenges. Fecal sludge is pathogen-rich and drying mitigates [...]

A Miniature Sanitation System in a Box

In 2011, the Bill & Melinda Gates Foundation ignited their Reinvent the Toilet Challenge to encourage innovative approaches to safe and sustainable management of human waste in developing countries. Answering the call, Duke University’s Center for WaSH-AID collaborated with MSR to develop the Reclaimer, a miniature sanitation plant in a box. Learn how the Reclaimer came to be and what makes this piece of technology so profound.
