Waste Enterprisers is an urban sanitation company operating in Ghana that treats human waste as a resource. It builds factories instead of treatment plants to produce "GreenHeat", a solid fuel derived from fecal sludge, which it sells to cover production costs and provide sanitation services. Its approach finances sanitation through a private business model turning waste into a renewable fuel. It expects to build its first full-scale commercial plant in Kenya in 2013-14 and expand to multiple countries within 10 years.

2. 85% of all human waste generated on the planet ends up
in the environment. Waste Enterprisers can’t live with
that.

3. More about Waste Enterprisers
WHO: An urban sanitation company currently operating
in Ghana, West Africa.
WHAT: Providing comprehensive human waste
management in cities, and doing so without placing a
financial burden on local governments or households.
HOW: By treating waste like a resource. We don’t build
treatment plants; we build factories. And our factories
receive wastewater/fecal sludge to produce
“GreenHeat”, a solid, fecal sludge-derived renewable
fuel.

4. WE’s approach to
financing sanitation
will revolutionize
sanitation.

5. Conventional approaches are
too expensive.

6. When treatment plants are built,
they break down.

Our revenues come from the sale of GreenHeat. This covers our production cost, rendering sanitation
the by-product of producing renewable fuel. Pretty nifty.
