The generation of solid waste is one of the greatest challenges of contemporaneity, specifically in Brazil, there was an increase from 67 million to 79 million tons per year, between 2010 and 2019. That said, in 2010 Law 12.305 / 2010, called National Solid Waste Policy (PNRS), which established, in order of priority, the non-generation, reduction, reuse, recycling, treatment and environmentally correct final disposal of waste, the Municipal Plan for Integrated Solid Waste Management (PMGIRS) in which describes the actions related to the management of urban solid waste and the strategies to protect human health and the environment. Given the importance of the PMGIRS for environmental management in the urban environment, the study of its applicability is justified, in which this article will address the city of Piracicaba, located in the interior of the State of São Paulo. In which, the objective of the research is to diagnose the practices related to agroforestry residues; evaluate the current state of the objectives proposed by the Municipal Solid Waste Plan; construction of a SWOT matrix; prepare a prospective analysis of agroforestry waste services and also an action plan for municipal waste. For this, the methodology used was the formal, exploratory, ex post facto, cross-sectional study in time, carried out from the prospection of articles, theses and dissertations in the Web of Science, SciELO and Digital Library of the main Brazilian universities . It can be concluded the concern of the municipality for the proper disposal of pesticide containers, in which the Cañeros Cooperative (COPLACANA) has a prominent role in practically all stages of reverse logistics in compliance with current legislation, however , the document did not comply with the guidelines for organic agroforestry waste, especially with regard to its reuse of energy and fertilizers.
