Collection and Flaking
Waste car bumper bars are collected from smash repair shops across the Sydney basin. They are sorted into their polymer types most commonly PP (polypropylene) and ABS (acrylonitrile butadiene styrene). They are then manually checked for contamination such as metal clips or other plastic components for example headlights. The bumper bars are fed into a shredder and granulator producing a flake approximately 10mm.
