Short description of the project: Malodor nuisance is a major risk factor in the adoption of effective fecal sludge management. It has been reported that filthy and smelly latrines motivate people to practice open defecation in areas with poor sanitation. This project focuses on what can be done to address the odor issue. The challenges of mitigating odor nuisances are very significant, owing to the highly odorous nature of fecal matter, the multiple ways that odorants can be released to the atmosphere, and the very low concentrations at which these odorants cause nuisance. Malodor can be released, evolve and cause nuisance at the source directly in toilets, during storage, handling, processing and disposal of fecal waste. Effective methods for preventing, capturing and destroying odors are required for successful adoption of any toilet or sanitation technology being developed. Goals: Conduct a broad survey to define the landscape of odor nuisance and control in all types of sanitation systems currently in use in developing countries. Determine the applicability of traditional and emerging filtration options to control odor using biochars both as an adsorbent and as a support material for bacteria in biofilters. Evaluate odors emitted from Reinvented Toilet systems and emerging fecal sludge management (FSM) methods specifically, i.e., primarily fecal odors, but also including combustion or drying of fecal sludge. +++++++++++ Documents available for download below: 1 - Presentation on odors in Fecal Sludge Management: A Roundtable Discussion, FSM3 Conference in Hanoi, Vietnam, Jan. 2015 (by Deshusses, M. and Linden, K.)
