Modeling the next generation of on-site sanitation systems

Luiza Cintra Campos

Luiza Cintra Campos of the University College London has won a US$ 100,000 Gates Foundation grant to to develop a simulation tool to evaluate new on-site sanitation technologies. By including parameters such as pit latrines served, distance to treatment, and potential for energy recovery, the simulation tool can aid communities in determining the best new systems for local needs.

Ms. Campos’ project was one of 31 to be awarded a grant on 7 November 2011 in the “Create the Next Generation of Sanitation Technologies” topic in round 7 of the Grand Challenges Explorations initiative.

Other interesting project proposals that won a grant include:

A Revolutionary Sanitation Technology with Superhydrophobic Materials submitted by Chunlei Guo of the University of Rochester, USA

Conversion of Human Excreta to Energy and Biochar from Jason Aramburu of re:char, USA

Effective Sewage Sanitation with Low CO2 Footprint from Marc Deshusses and David Schaad of Duke University in the U.S (read a university press release about this project)

Energy Recovery & Waste Treatment with Floating Biodigesters submitted by Rob Hughes and colleagues at Live & Learn Environmental Education in Cambodia

Floating Community Wastewater Treatment in Asia – Taber Hand of Wetlands Work! in Cambodia will field test a waste water treatment system that uses floating “pods” filled with wetland plants and moving water and sit directly under the toilet of houseboats in floating villages in Southeast Asia.

Self-Sterilizing Easy Clean Latrine Mat and Casting Form submitted by Paul Vernon and a team at Brighton Development, LLC in the U.S.

Urine-tricity: Electricity from Urine and Sludge submitted by Ioannis Ieropoulos of the University of the West of England, Bristol, UK
