ECOBOTS
Technology that cleans the world. The EcoDrone flies, finds and picks up street litter, and the EcoRecycler sorts everything for recycling.
Projects
Made by trailblazers.
Drones that pick up litter, apps that welcome refugees, games that teach empathy. Projects that left the classroom, took the stage and, in some cases, have already gone further.
Went beyond Trilhar
From Pitch for Peace to Brazil's TOP 10.
Nova Jornada was born in Trilhar UNESCO Maker Labs, in the full-time class 2001 at CIEP Cecília Meirelles. Today it's a finalist in the Brazilian Entrepreneurship Olympiad, a national competition between public and private schools.
The problem the students chose was xenophobia. Their solution is an educational game, both digital and physical, that simulates a refugee's journey on arriving in Brazil and builds empathy from school age.
