Application of Coffee Production Waste to Obtain Composites with Biopolimeric Matrix of PBS and ECOVIO

Abstract

Numerous environmental problems have arisen due to excessive production and consumption of non-renewable polymers. Thus, some strategies have been developed to mitigate the impacts, including degradable biopolymers,
PBS, and ECOVIO, whose properties are improved by adding vegetable fibers. This work aims to obtain composites whose biopolymeric matrix will be reinforced with coffee residues and to evaluate their mechanical properties. The methodology consisted of drying, extrusion, dehumidification, injection, and tensile testing. The added residue showed good interaction with the matrix, reduced the elongation and ductility of the composites, and increased their rigidity. Thus, it was concluded that the composite (PBS WC 70/30) increased 62.5% in the elastic modulus, showing that it is the best material among those studied.
