A proposal to establish a mechanical sorting plant at the Campina Grande do Sul landfill in Paraná

Abstract

This study presents a proposal to improve solid waste management in the municipality of Campina Grande do Sul, in the metropolitan region of Curitiba – PR. The initiative arose from the identification of weaknesses in waste sorting and disposal systems, observed through local data collection. Therefore, the need for technological and integrated solutions is evident, especially for small municipalities that face high per capita waste generation. As a theoretical and technical basis, the article by Borja Velázquez Martí (2024) was analyzed, which addresses technologies applied to waste separation, highlighting the Rotary Screen, known as Trommel, a technology that proves to be more suitable for local needs. The central proposal consists of the implementation of a Mechanized Sorting Plant (UTM), with the acquisition of two main pieces of equipment: the COMPAKTOR 300 Mobile Shredder and the TROMMEL SB 15.44 W Hybrid Mobile Screen. These devices promote greater efficiency in sorting, reduce waste volume, increase material reuse, and ensure compliance with environmental and safety standards. According to Brazil (2010), the initiative is aligned with the National Solid Waste Policy (Law 12.305/2010), the principles of Reverse Logistics, and the UN Sustainable Development Goals. The expected impacts involve environmental, economic, and social gains, such as reduced waste sent to landfills, job creation, and institutional enhancement. It is concluded that the proposal is viable, strategic, and sustainable for the municipal context.
