Plastic Injection moulding (PIM), produces a wide variety of plastic parts which are useful for various industrial applications. In few areas of Rajasthan, waste white marble-dust is abundant and creating the land pollution. In this paper, to make workable materials, for automobile interior, two compounds viz. PP-composite filled with TiO2 as filler and the other PP-composite with waste white marble micro-dust as filler were fabricated and their thermo-mechanical behaviour analysed with dynamic mechanical analysis. PP-TiO2 with 10 weight % shows maximum elastic modulus in all the PP- TiO2 compounds which was owing to the restriction of the molecular chain motion which creates more bonding effect. Similarly,
