Short description of the project:
The RTI-led team — which includes individuals at Colorado State University and Duke University — is developing a fully integrated toilet system that combines electrochemical disinfection technology for liquid waste processing and recovery, with a revolutionary new biomass energy conversion unit to both process the solid waste and convert it into energy.
Goal(s):
This project consists of three primary goals: 1) prove that human solid waste can be converted into a burnable fuel through drying/dewatering; 2) prove the use of thermoelectrics to convert thermal combustion energy into stored electrical charge; and 3) prove that liquid waste can be treated through electrochemical disinfection. Additional goals include minimizing cost – capital, labor, and O&M; minimizing energy use; and developing initial partnerships for implementation.
Objectives:
The core project objectives are: 1) develop a sewage separation and conversion unit that produces combustable fuel from human feces and other solid wastes; 2) develop a biomass combustion module that uses thermoelectrics to generate electrical energy from the combustion of fuel created from human waste; 3) Develop an electrochemical disinfection system that prepares liquid recoveres from mixed human waste for disposal or reuse in an environmentally responsible manner; 4) Integrate all operational systems and achieve system TRL6; and 5) achieve incentive target of TRL7. (TRL = Technology Readiness Level)
Research or implementation partners:
Duke University and Colorado State University are our key research partners. We are currently developing implementation partners based on a variety of discussions we have held with potential partners before, during, and after the design conference in Barcelona in April 2013 and a recent trip made by several RTI staff to Delhi, Ahmedabad, Trivandrum, and Mumbai in India in May 2013.
