What goes wrong?(BMGF brainstorming 2010)
� Too high research focus on technicaloptions at household and/or treatment level.
� Too much dependence of pilot projects on publicsubsidies/ODA than identified markets.
� Insufficient institutional linkages, incl. PPP.
� Missing private (agric) sector links, market analysis
and capacities for business modeling.� Missing focus on scalable options with cost
recovery for the sanitation service chain.

Which knowledge gaps should we address in
developing countries?
� Formal sector: More knowledge of reuse businessmodels at different scales to support a paradigmshift in waste management from treatment for
disposal to treatment for reuse.
� Informal sector: More knowledge on context specifi c health risks & options for risk mitigation to
address risk perceptions and cultural concernslimiting the move of reuse from its informality toformal recognition.
