Abstract: The invention relates to a polyolefin composition comprising a) 5 - 30 wt% (based on the overall weight of the polyolefin composition) of at least one polypropylene homopolymer; b) 25-60 wt% (based on the overall weight of the polyolefin composition) of a blend of recycled plastic material comprising polypropylene and polyethylene in a ratio between 3 : 7 and 49.5 :1, which is recovered from a waste plastic material derived from post-consumer and/or post-industrial waste; c) 20-50 wt% (based on the overall weight of the polyolefin composition) of at least one particulate filler, in particular talc, and optionally further additives, wherein the sum of all ingredients adds always up to 100 wt%, wherein the polyolefin composition has a melt flow rate MFR2 (230°C, 2.16 kg, measured according to ISO 1133) of at least 3.5 g/10 min; and a tensile modulus at 23°C of at least 3 GPa (ISO 527-2).
