Utilização de resíduos de cacau em compósitos poliméricos à base de poliolefinas

Abstract

This study analyzed the viability of adding cocoa shell flower and cocoa nuts flower in to polyolefins polymers. Brazil is the 7th greatest producer of Cocoa, and this largest production generates a lot of waste that spoils the soils. This study collected this waste, reduced in to flour, was characterized and added to the pure polymer. This composite was subjected in to thermogravimetric test, rheometry test, flow rate test, microstructural and mechanical characterization. As a result, the composite became harder than the pure polymer, but less ductile. However, it became economically and environmentally viable as a load material, since it reduces the composite final price in relation to the pure polymer and takes out the waste that has little practicable uses.
