The objective of this study is to evaluate the characteristics of polymeric composites containing different levels of addition of bean residue. To this end, agricultural residues were first reduced to particles and characterized "in natura" through tests for moisture content, bulk density, content of extractives, lignin and ash and by thermogravimetry technique. Then, the particles were dried and selected based on their granulometric fractions to make low-density polyethylene (LDPE) composites with addition levels of 0, 10, 20, 30 and 40% bean residues. The polymeric material and the bean waste particles were hot-extruded to obtain strands and then pellets; the resulting materials were then molded and hot-pressed. After fabrication, the specimens were subjected to physical testing for humidity, density, water absorption, and flammability and to mechanical testing for tensile strength. Transmission electron microscopy (TEM) also was performed. The results showed that the lignocellulosic material had decreased density and mechanical properties and increased water absorption properties after 24 h of immersion, and the moisture content in the samples increased as a function of bean waste substitution level in the polymer composite materials. These results may be related to the intrinsic chemical characteristics demonstrated by this material in the physicochemical characterization: low density and low contents of holocellulose, lignin and extractives. The mechanical properties were also influenced by the pores created by the bean particles, which may have contributed to the creation of larger zones of weakness in the samples.

“…For Veloso et al ( 2021), the reduction in tenacity values is associated with intrinsic factors to both materials (polymer and waste). In addition, low tenacity values can directly affect the impact resistance of the composite (Coutinho et al 2003;Pereira et al 2017).…”
