Curitiba Brazil has a number of innovative waste management programs. Follow this link to view a short video that features Curitiba’s Green Exchange Program. The program operates by exchanging fresh food for recyclable items that residents collect and bring to a transfer station.

Also see information here on the documentary A Convenient Truth, a film that chronicles how this typical South American city is transforming itself  through innovative, sustainable community initiatives.  Curitiba’s ideas and expertise are being exported to other cities around the world. I haven’t seen the doc yet, but it appears to be worth a look.
