Improper disposal of waste cigarette butt is an aggravating factor for the environment. The lack of awareness of tobacco practitioner regarding the incorrect disposal further aggravates the environmental scenario, given the mistaken view about the environmental impacts caused by the same. The aim of this study was to incorporate 5%, 15% and 30% of the waste from cellulose acetate (CA) cigarette butt in polypropylene (PP) and characterize the compounds obtained, aiming at their proper disposal and recovery. Collected up butts on public roads and NGO Network Paper and Bituca for treatment, which it was being developed methodology for the treatment and purification of the CA cigarette butt. The merger took place by calendering and the specimens were produced by injection. The characterization was carried out by tensile testing, impact, hardness, fluidity, HDT and SEM. By the results obtained it is concluded that the blends showed a reduction in the mechanical properties and improvement in thermal properties with respect to the HDT. The fracture surface analysis in the blend containing 5% of cellulose acetate, it was observed the formation of cavities in the resulting matrix phase of the particle displacement. Some particles of CA diameter of 5 - 6 microns showed better surface adhesion due to better wettability between the matrix of PP and AC. The blend with 15% showed greater dispersion of the CA in the array that is distributed as dispersed spherical particles, proving that there is no physical interaction between the phases, since the balls are CA 'loose' acting as a filler in the matrix. The blend with 30% occurred reduction in particle size of CA due to the higher concentration and longer process that resulted in better distribution and interaction phases occurring matrix tension transfer to the particles CA, allowing plastic deformation and breakage particle that presents faceted. Thus it is feasible the incorporation of CA coming from the residue cigarette butt in PP.
