It is imperative to improve understanding of plastic losses throughout the plastics value chain and to develop appropriate strategies to mitigate the environmental impacts of plastics. To encourage the circularity of plastics, in this work composites based on virgin and recycled polypropylene and two types of natural fiber (coconut and sugarcane bagasse) with or without content of 10% by weight were prepared in a mono-screw extruder. Pelletized samples obtained by extrusion were stamped from plates obtained by compression in a bench press and these materials were characterized through measurement of density, hardness and melt flow index (MFI). The density results indicated good fiber-matrixadhesion for all types of fiber and matrix used. A slight decrease in the hardness of formulations in relation to the matrix was associated with uneven distribution of fibers in the matrix. The MFI results were sufficient for these materials to be submitted to traditional polymer processing methods.
