Abstract: Empty PET bottles after consumption, without adequate disposal, have serious negative environmental impacts. Reverse logistics is a sustainable solution, by reinserting the material in the life cycle. This paper reports the development of a procedure for economic analysis to assess whether it is attractive for scavenger cooperatives to participate in a project for selective collection of used PET bottles, in two scenarios: collection with municipal public schools functioning as voluntary delivery points, and as incentivised exchange points (in return for a reward to the schools). The procedure was applied to evaluate a used PET bottle selective collection project in the municipality of Volta Redonda, Rio de Janeiro State, Brazil. The results indicate that the project is economically viable and attractive to the cooperative investigated. The project is also beneficial to the city's public schools when functioning as incentivised exchange points, by generating revenue to sponsor educational activities.
