diapo - Energiser une révolution sanitaire en Afrique subsaharienne - Visuel
Proposing a renewable energy source from solid materials from waste water, sludge from latrines and septic tanks, to improve the health situation in Kigali.

In Kigali, half of the inhabitants of the city, that is 550,000 people, are not connected to a collective sewerage network. Moreover, the city does not have a waste water treatment plan. Sanitation is therefore a major challenge for the conurbation.

There is a blatant problem of sewerage in the majority of sub-Saharan African villages and in developing countries in general. Among the most significant obstacles are the high operating costs of conventional waste-treatment approaches.

There is a crucial need for innovation in this sector for large-scale efficiency while overcoming the financial obstacle.


Following the success in Ghana, Pivot Works plans to build a centre for the production and sale of energy based on human faecal matter and solid waste from waste water.

The project aims to support the building of a first unit at the discharge of the Nduba in Kigali where 100 m³ of waste water will be transported every day.
This initial stage serve to confirm the financial and technical viability of the system, depending on the demand in fuel and the impact on the climate.

The underlying principle of the Pivot Works marketing plan is to renew strategic alliances with cement multinationals. Targeting this industry is justified by the geographical coverage and the size that it represents.
For Pivot Works this involves encourage this market to expand, as it is both a major employer and an influential actor in the economies in which it operates, and also offers the possibility of attaining its environmental objectives and its corporate social responsibility obligations.

  • Production of renewable fuel (5 tonnes of fuel sold since the start of the activity).
  • Safe disposal of waste water and septic tanks for at least 500,000 people (since 2015 more than 3925 m³ of waste have been recovered).
  • Reduction of sanitary costs for the city valued in 2014 at 54 million dollars per year.
  • Creation of jobs after installation of the Pivot Works plant (26 jobs).
  • Reduction of greenhouse gas emissions (10.2 tonnes of CO₂ avoided since the factory has been in operation).
