Q&A with Gary Foutch
OSU professor works to offer
affordable sanitation in world
Q: I understand you're working to develop more efficient toilets worldwide and recently presented to the Bill & Melinda Gates Foundation, which has taken the lead in tackling the issue that 2.5 billion people worldwide lack access to safe and affordable sanitation. Tell us about your technology. How does it work?
A: We use the concept of viscous heating. Basically, we heat the mass by friction to the point where we can sanitize the waste for safe handling and even vaporize any water for recovery.
Q: What are its benefits?
A: No water or heat is required. The treated waste is safe for agricultural use or energy production.
Q: What has it been like to work with the Gates Foundation?
