Apart from improving hygiene by eliminating the risk of contamination by pathogens, an important objective of the treatment of fecal sludge in the FSTPs operated by Delvic is the valorization by production of added value derived products such as compost.

 

 

 

 

 

 

 

The compost thus obtained is of excellent fertilizing quality.

Indeed, according to studies conducted by the Senegalese Institute of Agricultural Research (ISRA), this compost fertilizing properties rival with those of chemical fertilizers for vegetables such as aerial vegetables (study on tomatoes), underground root vegetables (study on onions) and leafy vegetable (study on cabbages).

This same compost is used in parallel by Delvic in its own gardening and ornamental production.

 

 

 

 

 

Sludge can be valued also by the production of charcoal-like briquettes for domestic cooking.   Successful experiments were conducted by the NGO Water for People in Kampala, Uganda. A partnership is underway for the production of such briquettes in Senegal.
