Collection activity of the Cooperative, orange: collection with handcart, blue: collection with truck

forage tracking

The Forage Tracking project is mapping the tacit knowledge and spatial organization of informal recyclers in downtown Saõ Paulo.

We used location-detecting hardware and software to investigate how the Catadores, informal recyclers, find and collect material in the city. We are also developing participatory platforms that will help them to organize their activities and connect the cooperative to the citizens.

In our work with the recycling cooperative COOPAMARE, we try to increase visibility and understanding of the service they provide to the city.
