URBAN SOLID WASTE MANAGEMENT IN TERESINA-PI: AN ANALYSIS OF CHALLENGES AND GAPS

Abstract

This paper addresses the challenges faced by the municipality of Teresina in implementing the guidelines of the National Solid Waste Policy (PNRS), Law No. 12.305/2010. Teresina, the capital of the state of Piauí, has a population of over 902,644 inhabitants and presents a growing generation of urban solid waste, including recyclable material. The case study made it possible to identify the main advances and obstacles in waste management, considering aspects such as the implementation of selective collection, the participation of waste pickers’ cooperatives, the infrastructure of Voluntary Delivery Points (PEVs), environmental education, and the feasibility of public consortia for integrated waste management. Among the most relevant results, the following stand out: limited financial resources, dependence on the work of informal waste pickers for recycling, difficulty in fully implementing the Municipal Integrated Solid Waste Management Plan (PMGIRS), and the need to adapt former waste disposal areas.
