Electrochemical disinfection with integrated biomass oven for solid waste processing and energy harvesting

2011 - 2017 • RTI International, Research Triangle Institute

Purpose

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.

Activities

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.

Location of main activity

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 stands for Technology Readiness Level

Further information

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.

This was an RTTC grant.

RTI International is an independent, nonprofit institute that provides research, development, and technical services to government and commercial clients worldwide. Our mission is to improve the human condition by turning knowledge into practice. RTI is the implementing partner of the Sanitation Technology Platform (STeP), funded by the Bill & Melinda Gates Foundation (BMGF). STeP helps transformative sanitation technologies reach the 4.5 billion people worldwide who don't have access to safely managed sanitation by de-risking and accelerating innovative sanitation solutions. We help technology developers, commercial partners, and financing partners develop strong business models, field test products in real-world contexts, and identify and nurture the partnerships needed to achieve impact. RTI also implements the Nigeria Effective Water, Sanitation and Hygiene (E-WASH) project, funded by the U.S. Agency for International Development (USAID). Under this project, we expect to improve water delivery to 500,000 households by boosting the productivity and efficiency of State Water Boards (SWBs). Read more on our project page.
