Abstract: Provided is a waste thermoplastic olefinic resin-containing composition, which has excellent dimensional stability and weather resistance, allows production of high-quality of molded articles, shows improved physical properties, and is applicable to car bumper covers. The waste thermoplastic olefinic resin-containing composition comprises: 25-45 wt% of a waste olefinic resin having a melt index of 10-20 g/10 min.; 24-45 wt% of a polypropylene resin having a melt index of 100-250 g/ 10 min.; 9-50 wt% of an inorganic filler; and 0.1-1 wt% of a weather resistance stabilizer. The inorganic filler includes wollastonite and talc in a weight ratio of 8:2-2:0.1. The weather resistance stabilizer includes a modified hindered phenol. The resin composition optionally further comprises a thermal stabilizer.
