Abstract (en)
[origin: EP3604675A1] The invention relates to a method of manufacturing an artificial turf fiber (510). The method comprises: creating (302) a polymer mixture (100, 200) comprising molten plastic waste and a molten compensatory polymer (104), the plastic waste comprising one or more aged polymers (106), the compensatory polymer being an unaged polymer, the MFI of the compensatory polymer being at least four times higher than the MFI of the one or more aged polymers; extruding (304) the polymer mixture into a monofilament (406); and fabricating the artificial turf fiber from one or more of the monofilaments.
