Episode Details

374Water’s Marc Deshusses provides unique insights on supercritical water oxidation and its ability to destroy PFAS. Marc also discusses his early efforts to harness the power of supercritical water oxidation, overcoming technological obstacles, and the path towards commercialization.

In this session, you’ll learn about:

• What supercritical water oxidation is
• What supercritical water oxidation does (hint: it will not only remove stains from your laundry, it will eviscerate your laundry)
• How Marc applied for and received funding in 2013 from the Bill & Melinda Gates Foundation’s Reinvent the Toilet Challenge
• The history of technical challenges for supercritical water oxidation that blocked prior commercialization attempts
• The best applications for supercritical water oxidation
• The undesirable compounds in biosolids that supercritical water oxidation treats 
• Why landfill operators don’t like biosolids deposited in their landfills
• The outputs of supercritical water oxidation: clean water, waste heat and resource recovery (including phosphorous)
• How supercritical water oxidation treats and destroys PFAS and other emerging contaminants
• Why supercritical water oxidation is, in Marc’s view, the best option to treat and destroy PFAS
