The effect of PP contamination in recycled high-density polyethylene (rPE-HD) from post-consumer bottle waste and their compatibilization with olefin block copolymer (OBC)

Erdal Karaagac et al.

Summary: This study investigates the effects of different percentages of rPP contamination and OBC compatibilizer on rPE-HD from plastic detergent bottle waste. The results show that increasing rPP contamination leads to deteriorating mechanical properties, while the addition of OBC significantly improves performance and adhesion.

Determining the PE fraction in recycled PP

Age G. Larsen et al.

Summary: The presence of a polyethylene fraction in recycled polypropylene affects its processing and properties. Different methods were compared to determine the PE content, with consistent estimates achieved through DSC, NMR, FT-IR, and gel content measurements. Experimentation with various material grades was conducted to understand how they impact the results.

Characterization of Composition and Structure-Property Relationships of Commercial Post-Consumer Polyethylene and Polypropylene Recyclates

Markus Gall et al.

Summary: Efforts towards a circular plastics economy are putting pressure on recycled plastics, especially recycled polyethylene and recycled polypropylene, to enter new markets. A detailed understanding of composition and structure-property relationships of post-consumer recyclates needs to be developed to meet the demands of more circularity.
