Brazilian waste pickers gain an inexpensive way to fuel their vehicles using leftover cooking oil.
The estimated half-million garbage pickers in Brazil, known as catadores, turn waste into gold: they sort out recyclable items in the country’s dumps, then sell their findings to recycling companies. But the process of getting the recyclables to their final destination involves fleets of fuel-consuming vehicles.
Now — with help from some MIT students — the catadores have a less-expensive and environmentally friendly fuel option: recycled cooking oil.
In summer 2010, members of MIT’s biodiesel team, along with a Media Lab student and one Brazilian MIT student, traveled to Sao Paulo, Brazil, to begin work on the project, called Green Grease. They worked with Rede CataSampa, one of the many catadores cooperatives, to convert two of its large trucks to run directly on filtered vegetable oil.
