|Vortex Bioreactors for the Processing of Fecal Sludge and Waste Water|
|Mike Allen, Plymouth Marine Laboratory, Plymouth, United Kingdom - GB|
– Fall 2013
Mike Allen of Plymouth Marine Laboratory in the United Kingdom proposes to develop a low cost, vortex-based bioreactor that is driven by hand or a bicycle to separate fecal matter from waste water and at the same time introduce bactericidal agents to decontaminate the waste for recycling or safe disposal. In Phase I they designed and built a desk-top vortex bioreactor to test different biocidal agents for their ability to kill bacteria, and to be physically immobilized to enable long term use. Copper embedded onto alginate beads was the most effective and robust combination, and glass beads were shown to bind helminth eggs to enable their separation. They also characterized material flow through the vortex bioreactor to optimize performance. In Phase II, they will work to effectively incorporate the biocidal agent, which requires a high level of mixing, with a method for separating and removing helminth eggs, which requires low turbulence, into one vortex bioreactor by testing different methods of binding helminth eggs. They will also perform field testing with experienced partners, and further optimize the reactor design to reduce costs and promote easy use.
|A Revolutionary Sanitation Technology with Superhydrophobic Materials|
|Chunlei Guo, University of Rochester, Rochester, NY, United States - US|
Chunlei Guo of the University of Rochester in the U.S. proposes to develop superhydrophobic materials that not only repel waste for use as a self-cleaning surface for latrines, but also can be used to capture and slough clean water into storage containers before it evaporates or is contaminated.
|A Solar Steam Sterilizer for Treatment of Human Waste|
|Naomi Halas, Rice University, Houston, TX, United States - US|
Naomi Halas and colleagues at Rice University in the U.S. will design and test a prototype sterilizer that employs metallic nanoparticles that absorb solar energy to convert water to steam sufficient for sterilization of human waste.
|Bioelectricity Generation from Domestic Waste|
|Caitlyn Butler, Arizona State University, Tempe, AZ, United States - US|
Caitlyn Butler, Mark Henderson and Brad Rogers of Arizona State University in the U.S. will adapt pit latrines to harvest organic substrates and nitrogen compounds in human waste using microbial fuel cells, which will transform the biochemical energy into carbon-neutral electricity.
|Biogas Generator Powered by Self-Sustaining Mixing Mechanism|
|Tim Canter, Frontier Environmental Technology, Rolla, MO, United States - US|
Tim Canter of Frontier Environmental Technology in the U.S. proposes to develop a biogas generator that employs a unique self-sustaining mixing mechanism to effectively treat concentrated wastewater and produce biogas without extra energy or trained personnel.
|Breathable Membrane Enclosures for Fecal Sludge Stabilization|
|Steven Dentel, University of Delaware, Newark, NJ, United States - US|
Steven Dentel of the University of Delaware in the U.S. will apply low-cost polymeric breathable membranes to fecal material and test their ability to not only protect groundwater from pathogen and contaminant releases but also to accelerate the drying and disinfection of these wastes.
|Conversion of Human Excreta to Energy and Biochar|
|Jason Aramburu, re:char, Austin, TX, United States - US|
Jason Aramburu of re:char in the U.S. proposes to use low-cost pyrolysis reactors to convert human waste into biochar, which can be used as a replacement for wood charcoal or chemical fertilizers. This project will also assess the income-generating potential of this biocharcoal.
|Creating Economic Incentives for Improved Sanitation|
|Mark Holtzapple, Texas A&M University, College Station, TX, United States - US|
Mark Holtzapple of Texas A&M University in the U.S. seeks to demonstrate that carboxylic acid fermentation can be adapted as a sanitation treatment to not only kill pathogens in the waste but also convert it to liquid fuels, compost, and potable water that can be used for economic gain.
|Direct Electricity from Fecal Sludge in Bioelectric Systems|
|Zhiyong Ren, University of Colorado Denver, Aurora, CO, United States - US|
Zhiyong Ren of the University of Colorado Denver in the U.S. proposes to develop a low-cost and easy-to-operate bioelectric system that uses microbes to break down waste and convert it to usable electricity. This technology could provide a self-sustainable solution for communities in need of both sanitary waste disposal and an energy supply.
|Effective Sewage Sanitation with Low CO2 Footprint|
|Marc Deshusses, Duke University, Durham, NC, United States - US|
Marc Deshusses and David Schaad of Duke University in the U.S. proposes to develop a bioreactor system which converts waste to biogas, which is then burned and the temperature amplified through a heat exchanger to sterilize the treated effluent. This system could capture and re-use greenhouse gases while providing effective sanitation in developing countries.
