About
The story of an engineer who watched water go to waste for 15 years
Yassine Rezgui, an engineer trained at Gobelins (Paris), returns to Tunisia in 2011 after eleven years in France. He spends nine years selling printing equipment — family group, official KBA distributor, offset presses — before setting himself a precise mission in 2015: cut industrial water consumption.
“Being selected for GITEX AFRICA Morocco is more than visibility. It's proof that what we're building at RYBSEN resonates beyond our original market.”
