dc.description.abstract
The essential shift toward a circular economy in the European Union is emphasized by regulatory initiatives such as the Green Deal containing the Packaging and Packaging Waste Directive (PPWD), which highlights the significance of sustainable plastic use and emphasizes an improved design for recycling. Despite this, due to its adaptability to diverse applications based on specific properties and processing requirements, polypropylene consists of a heterogeneous recycling stream currently leading to downcycling. To comprehensively understand the polypropylene packaging stream, this study characterizes various packaging types commonly encountered in plastic recycling collections. Additionally, it involves the examination of virgin blends comprising distinct molar masses and varying concentrations of high and low molar mass components. Mechanical, rheological (melt massflow rate, storage and loss modulus) thermal and morphological properties were investigated. The virgin blends exhibit consistent results in terms of the Modulus of elasticity, while the Elongation at break demonstrates greater sensitivity to variations in the blend composition, particularly concerning very high or very low molar masses. Notably, an incremental increase in the proportion of low molar mass polypropylene correlates with a continuous decrease in elongation at break until a tipping point. Polypropylene packaging shows the outliers and pitfalls such a stream must cope with. These findings hold significance for a polypropylene recycling stream, where high and low molar mass polypropylene is represented by different application and manufacturing methods. Despite the complexity and heterogeneity evident in waste streams, comparisons for an idealized post-consumer material stream validate the use of virgin blends as a possible comparison.
