Content - Summary

This library entry contains background documents and results for a grant which is funded by the Bill and Melinda Gates Foundation and led by David Auerbach (further information is also available on the SuSanA discussion forum, see link below).

Short description of the project:

This project will support the implementation of efficient fecal sludge management systems, the production of by-products made from fecal sludge, and the demonstration of the market viability of these by-products. The project will also allow Sanergy to build an enabling environment in terms of policy and advocacy.

Sanergy began working in Nairobi in November 2011. We design and manufacture low-cost, high-quality sanitation facilities. Developed by our engineers, the Fresh Life Toilet (FLT) is pre-fabricated at our local workshop. Our FLT features qualities users value most:

Hygiene: FLTs are made of high-quality materials that are easy to keep clean and maintain.
Accessibility: FLTs have a small footprint that enables them to be install them close to homes
Affordability: FLTs are cost-effective and include essential features like hand-washing facilities.

Grantees by the BMGF have been using our setup to test various research aspects.


(1) Establishment of scalable supply chains for sourcing fecal sludge at scale, including taking on fecal sludge from sources other than Sanergy’s network of franchised toilets
(2) Development of commercial processes to convert fecal sludge into saleable by-products, such as active composting processes, biogas production, high-protein animal feed, biochar, and urine valorization
(3) Development of markets for by-products of fecal sludge


To promote the safe collection of fecal sludge and the delivery of hygienic sanitation services to low-income populations in urban informal settlements by establishing scalable supply chains for sourcing fecal sludge, developing processes to convert fecal sludge into saleable by-products, and developing the markets for by-products of fecal sludge
