Selective recovery of polypropylene (and polyethylene) from mixed plastic wastes
Project ID: D2021-43 Background Polypropylene (PP) is a thermoplastic polymer used in packaging materials, consumer goods, automotive components, and medical devices. It is difficult to recover PP from mixed plastic waste streams; PP has a similar density to polyethylene (PE) and cannot be selectively separated from PE via the sink-float methods...
