Recovering water, nutrients and energy from liquid and solid wastes generated in sanitation systems is a high priority where resources for agricultural production are already limited. At present, resource recovery is happening mostly unplanned and is neglecting public health and environmental issues.

To promote and implement globally and at commercial scale recovery and safe reuse models of resources generated from liquid and solid waste streams in order to promote food security, cost recovery in the sanitation sector, and livelihood opportunities, while safeguarding public health and the environment in poor urban and peri-urban areas in developing countries.  

Direct beneficiaries include: (1) small and medium enterprises in the sanitation-agriculture-energy production interface (2) urban population of Kampala and Lima, especially the most exposed household members suffering from poor sanitation and exposed to health risks (3) Direct users of SSPs: public and private sector and authorities at various scales.

1. The implementation of economically viable business models increases the scale and viability of productive reuse of water, nutrients, organic matter and energy from domestic and agro-industrial waste streams.
2. To safeguard public health in the context of rapidly expanding use of wastewater, excreta and greywater in agriculture and aquaculture and protect vulnerable groups from specific health risks associated with this pattern of agricultural development.
