what we do

Safi Sana is a Dutch holding enterprise that designs, constructs and operates waste-to-energy factories in developing countries.

Our factories are sold to clients (government, industry) or developed to be operated by Safi Sana. Each factory is a standalone entity which receives support from the Safi Sana technical and marketing servicing team for Quality Assurance.

Our model

Our model

Our business model is based on the sale of turnkey factories, servicing fees and operational revenue of commercially-run waste re-use factories.

At factory level, the business objectives are to receive tipping fees for waste intake, to sell energy and agri input products from the waste treatment process, and to cover cost of treatment, sourcing and maintenance.

How does it work?

  • We collect both faecal and organic waste from urban slums (from toilets, food markets, industries and slaughterhouses).
  • We use it as input in our factory.
  • In the factory, waste is treated in a digester to create organic fertilizer, irrigation water and biogas.
  • The biogas is subsequently used to produce electricity.
  • The irrigation water and part of the organic fertilizer are used to grow seedlings.
  • Sales of these end-products (i.e. electricity, bio fertilizer, seedlings) cover operational cost which allows us to ensure long-term sustainability.
