The purpose of research is to mix the fly ash from municipal solid waste incinerator in the recycled Polypropylene and to recycle. The specimen was produced by mixing 20 wt.% of MSWI fly ash at maximum in the recycled Polypropylene and the particle size analyzer, DSC, TGA, SEM and UTM instruments were used to analyze the physical chemical properties of the specimen. As a result of measurement, the average particle size of MSWI fly ash was $18.08\;{\mu}m$. In TGA analysis, the temperature of specimen S-5 at 50% of weight decrease was risen by $7^{\circ}C$ higher than specimen S-1. In UTM measurement, specimen S-2 showed the maximum strength for tensile strength and specimen S-3 showed the maximum strength for flexural strength. But, impact strength was decreased according to the increasing proportion of MSWI fly ash. In conclusion, when the proper amount of MSWI fly ash was added to the recycled Polypropylene, thermal endurance, tensile strength and flexural strength could be increased, but impact strength was decreased.
