Resumo

Much research has been carried out around the development of alternative
materials with the most varied purposes aiming at a positive contribution to the
environment through the use of solid waste. Among these solid contaminants,
the one produced in industrial effluent treatment stations, such as tanneries,
stands out, where leather processing has a negative environmental impact,
since the chemicals used in the treatment of raw materials, including
chromium salts, have a high degree of toxicity. These residues can be used
in the manufacture of alternative materials to promote the reduction of the
environmental impact generated by them. Therefore, this study aimed to
verify the feasibility of incorporating waste produced in a tannery effluent
treatment station, known as “leather powder”, in a polymeric matrix of
recycled polypropylene in the proportions of 10 and 20%, by means of
making specimens by extrusion and injection processes. The specimens
were analyzed in relation to the mechanical tests of tensile strength and
Izod impact. The specimens containing 10 and 20% of leather powder had
their resistance increased by 2.10 and 7.65% with respect to traction, 9.7 and
24.59% with respect to impact, respectively. The homogeneous distribution
of leather powder particles in the polymeric matrix may have contributed
to the increase in mechanical strength. This homogeneity was verified by
the morphological analyzes. Thus, it is feasible to insert leather powder in
recycled polypropylene in the proportions of 10 and 20%, presenting itself as
a solution for the proper disposal of these residues, thus having a favorable
contribution to the environment.
