It was during a humanitarian action carried out in the region of Kasserine that Olfa, co-founder of Biothelya, discovered the exceptional potential of a generous and loving land, ZELFENE and THALA: capitals of prickly pear cultivation.

There began the idea of a project to promote this fruit, described by the women of the region as the "king of fruits" with exceptional properties.
And which, through its ecological benefits (no need for water, fights the advancement of the desert, zero waste), its economic action in isolated regions, and the job creation it can offer, would ensure a positive impact on the local population.
