In a northern Tunisian olive grove, Yassine Khelifi's small workshop hums as a large machine turns olive waste into a valuable energy source in a country heavily reliant on imported fuel.

Holding a handful of compacted olive residue -- a thick paste left over from oil extraction -- Khelifi said: "This is what we need today. How can we turn something worthless into wealth?"
