Tires are solid waste that need proper disposal to avoid environmental and health damage or not to serve as breeding grounds for diseases such as Dengue, Chikungunha and Zika. Concerns about these types of materials motivated legislation such as CONAMA nº 416/2009, which prevents environmental degradation caused by waste tires and seeks the correct destination, and the National Policy on Solid Waste, law 12305, which, due to its effectiveness, establishes the indispensability the structuring and implementation of reverse logistics, in addition to bringing shared responsibility in the production chain. In view of the concern with the post-consumption of tires, such as the environmentally correct destination, we sought to analyze how reverse logistics of post-consumer automotive tires occurs in the city of Teresina - PI, through field research in those involved in the chain, such as tire shops, dealerships, resellers, tire renovators and a recycling company. Tire reform, in addition to being more economical for consumers and ecologically correct, is an alternative to post-consumer tires that have the proper structure to reform, also preventing the use of liters of oil, as well as the release of CO2. In the three renovators visited in the city of Teresina, 91,560.0 liters of oil were no longer used monthly, with 247,615.09 cubic meters of CO2 not released and the annual forecast of 1,098,720.0 liters of oil with 2,971,381, 13 cubic meters of CO2 not being emitted.
