Indicadores de desempenho técnico e ambiental aplicado à gestão de resíduos sólidos urbanos do município de Crateús - CE

Abstract

The increasing generation of urban solid waste has become one of the main environmental, social and economic challenges for public administration. The lack of efficient management can result in negative impacts, requiring structured solutions. In this context, the National Solid Waste Policy (PNRS), instituted in 2010, establishes guidelines to improve management and promote sustainability. However, for these guidelines to be effective, it is essential to monitor the efficiency of the system through technical and environmental performance indicators, which allow identifying weaknesses and proposing improvements. This study evaluated the management of urban solid waste in Crateús – CE, applying a set of indicators adapted to the particularities of management in the municipality and to the PNRS criteria. The Waste Management Condition Index (ICGR), the Updated Wasted Management Condition Index (ICGRA) and sustainability indicators were applied. Data collection included interviews with representatives from the Department of the Environment, the Department of Infrastructure, and the Association of Recyclable Material Collectors of Crateús (Recicratiú). The classification obtained that management is inadequate, requiring structural and operational improvements. The indicators analyzed pointed out weaknesses, mainly those related to the PNRS and new ICGRA techniques. The results demonstrated that municipal management has deficiencies, especially in the final disposal of waste, especially in the low adherence of the population regarding selective collection services and in the absence of effective strategies for the reuse of organic waste. The classification obtained indicated that management is inadequate, requiring structural and operational improvements. In view of this, actions were suggested to expand selective collection, strengthen reverse logistics, and establish an efficient plan for the destination and final disposal of waste, with the urgent eradication of the landfill. However, although there are advances in the management of solid waste in the municipality, there are still challenges to be overcome in order to achieve sustainable, environmentally responsible and safe management.
