Short description of the project:
The project assesses the potential of modern biotechnology to deliver effective bio-additives which can accelerate decomposition processes and extend the lifetime of pit latrines. It will also build a sound scientific understanding of the key factors influencing decomposition processes, including the potential of pit design to improve fill rates and longevity. At the same time, research will be undertaken to build a deeper understanding of the current user experience, needs and aspirations of on-site sanitation that can be used to inspire improved, lower cost on-site sanitation options for the poor.
Goals:
To improve the lives of those with access to poor or insufficient sanitation by (i) delivering deeper knowledge of excreta decomposition, user needs and aspirations, and application of biotechnology and (ii) developing innovative, compelling concepts for non-piped sanitation
Objectives:
To identify scientific advances from a variety of fields that could improve pit latrine performance, for example by accelerating faeces decomposition, or decontaminating faeces
To understand decomposition processes and the influence of on-site sanitation design factors on performance to support bio-additive and/or pit latrine product development.
To assess the current/potential market and understand consumer needs/aspirations for on-site sanitation, so any new products/designs will be adopted and used
To generate new on-site sanitation concepts for further development and commercialization, that may lead to a step change in performance, cost-effectiveness, and user adoption, use and maintenance of on-site sanitation (workstreams 5 and 6)
To create a platform for future research and development based on key insights and potential partnerships to further accelerate improved on-site sanitation for the poor.
