From Campus to Commerce EP. 2 – Duke University


Duke University engineering professor Marc Deshusses is a co-founder of 374Water solutions which is inventing a new toilet to serve the 2 billion people in parts of the world that lack sewer or water service. One of the very exciting projects that we’re working on is a neighborhood treatment system that can handle the fecal waste for a thousand, or three thousand, or maybe even 30,000 people that can handle the fecal waste for a thousand, or three thousand, or maybe even 30,000 people and it works with a novel process that is called supercritical water oxidation and it works with a novel process that is called supercritical water oxidation Supercritical water oxidation is a high temperature, high pressure process; the “pressure cooker on steroids.” Supercritical water oxidation is a high temperature, high pressure process; the “pressure cooker on steroids.” So, something like four seconds, we go from fecal waste to carbon dioxide and water. Lately we’ve been putting a lot more focus into recovering this energy Lately we’ve been putting a lot more focus into recovering this energy Lately we’ve been putting a lot more focus into recovering this energy and being able to run the units with just the energy that is embedded in the fecal waste and not depend on the electrical grid. We know we can do it. And that’s I think, one of the motivations is keep pushing to achieve success.
