PURPOSE: A rear side mat using scrapped EPDM(Ethylene Propylene Diene Monomer) for a vehicle and a manufacturing method thereof are provided to recycle waste resources and to prevent environmental contamination by substituting the raw materials of an existing rear side mat for the waste resources. CONSTITUTION: A rear side mat for a vehicle is comprised of 5-10 wt% of SBS(Styrene-Butadiene-Styrene), 60-70 wt% of scrapped EPDM desulfurization, 15-20 wt% of PP(Poly Propylene), and 5-15 wt% of oil. The scrapped EPDM desulfurization is comprised of desulfurizing fine powder substances comprised by finely grinded scrapped EPDM rubber. The scrapped EPDM rubber remains after separating the iron core from the scrap generated in the production process of a weather strip or from a scrapped weather strip recovered from a scrapped vehicle. A particle size of the fine powder is under 200 micron. The oil is paraffin oil.
