Waste in exchange for food: the ecology in Brazil fights hunger

Green Exchange Program "An appetite for recycling"

With four kilograms of separated waste you bring home a pound of vegetables and fresh local vegetables. It happens in Brazil, in the city of Curitiba.
The city had two major problems: a surplus of food production, which kept prices too low by dropping the income of farmers, and widespread poverty among the non-agricultural population.
It's born for this, the Green Exchange program: the council buys surplus food from manufacturers and distributes them to disadvantaged groups in exchange for their waste.
In this way the collection has been dramatically increasing, the waste has decreased dramatically, the population had a poorer nutritional support and, finally, the prices of agricultural products have become more stable and higher for farmers.
