Design of an Industrial Facility for Recycled Polymer Granule Production

ABSTRACT: With the global increase in the production and disposal of polymeric waste, it becomes crucial to develop sustainable solutions that promote the circular economy of recyclable materials. This work presents a technical feasibility study for the implementation of a production unit for recycled polymer pellets, using a mixture of High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Polypropylene (PP) as raw material. The proposal aims to map the complete production process, from the collection and receipt of the recycled material to the granulation and sale of the pellets, including the characterization of the materials and the necessary compatibilizers and additives. The definition of production capacity, equipment selection, and industrial layout will also be addressed. The study includes a logistical and financial analysis, even if preliminary, for a hypothetical organization located in the region of São José dos Pinhais—PR, for the processing of recycled PP-PE blend. To carry out this study, basic concepts of industrial engineering design were applied. Information on the process and characteristics of a hypothetical PP-PE formulation was obtained through bibliographic research. The study allowed for important considerations regarding the development of a basic industrial design for processing recycled polymer. Preliminary results indicate existing demand in the metropolitan region of Curitiba (southern Brazil) and potential for job creation, including the use of labor from waste pickers distributed throughout the region.
