Proposta de protocolo para a avaliação de unidades de Valorização de Resíduos Recicláveis (UVR) da região Oeste do estado do Paraná

Abstract

This study aimed to develop a model protocol for evaluating the performance of Recyclable Waste Recovery Units (UVRs). The need for an effective protocol arises from the growing importance of proper solid waste management and the search for objective methods that assist in decision-making to improve the efficiency of UVRs. The proposed protocol includes a list of qualitative indicators, grouped into four main categories: physical, environmental performance, operational technical, and socioeconomic performance. These indicators were selected to provide a comprehensive and detailed view of the efficiency of UVRs in various areas. The physical category covers aspects such as infrastructure and processing capacity of the units. Environmental performance indicators consider the reduction of environmental impacts, resource use efficiency, and waste minimization. The operational technical dimension focuses on aspects such as process efficiency, equipment maintenance, and operational safety. Lastly, socioeconomic performance assesses the impact of UVRs on job creation, social inclusion, and economic benefits for the community. Together, the four indicators make up the quality index of activities developed by UVR. To validate the protocol, the Paraná III hydrographic basin, located in western Paraná, was used as the planning unit. The UVRs were chosen based on the criteria that the municipalities are included in Itaipu Binacional Solid Waste Management program. During this phase, data from 34 UVR were collected to verify the effectiveness of the protocol in measuring the performance of the units through the UVR quality index (IQUVR). From the obtained data, fifteen UVRs achieved an excellent quality index, IQUVR, and nineteen UVRs reached a good IQ-UVR. The units classified as excellent stood out for their robust infrastructure, operational efficiency, and positive environmental impact. On the other hand, the UVRs with a good rating showed areas of high performance but also some points for improvement. These UVRs, although effective in various aspects, still face operational and environmental challenges that can be overcome with the application of more advanced and sustainable management practices. The validation of the protocol demonstrated that it is an effective and robust tool for evaluating UVRs, providing an objective basis for decision-making. Furthermore, the IQ-UVR serves as a guide to identify areas for improvement and promote the continuous evolution of waste recovery processes. The application of this protocol can, therefore, guide managers and authorities in the allocation of resources and the development of strategies aimed at the sustainability and efficiency of recycling operations.
