TL;DR: In this paper , a two-step melt blending process is used to prepare polypropylene (PP) and carbon black (CB) nanocomposite, and the results showed that the optimum value of CB in PP nanocompositionite is 0.5 wt%, at which the majority of the properties are maximized.
Abstract: Waste management of the nonwoven polypropylene (PP) fabric has become an emerging issue due to its increased usage. This study presents the upscale recycling of PP nonwoven fabric scrap generated during medical-grade disposable gown manufacturing. To prepare PP and carbon black (CB) nanocomposite, a two-step novel melt blending process is used. A maximum density of 937 kg/m(3), shore D hardness of 74.45, and highest improvement in UV degradation resistance with a carbonyl index of 0.40 is recorded at 2 wt% of the CB while melt flow index is the lowest at 0.5 wt% of the CB. The results of this study revealed the peak melting point (161.81 degrees C), thermal degradation temperature (421 degrees C), highest flexural strength (49.16 MPa), and Izod impact strength (6.76 kJ/m(2)) are at 0.50 wt% of CB loading. A morphological study indicated that the highest agglomeration of CB particles was found at 2 wt% CB. The results showed that the optimum value of CB in PP nanocomposite is 0.5 wt%, at which the majority of the properties are maximized. This research might pave the way for the recycling of nonwoven PP waste fabric and provide an alternative to the exciting virgin raw materials.

TL;DR: In this paper , the feasibility of valorization of post-consumer recycled flexible polypropylene (PCPP) by incorporating fumed nanosilica (NS) was evaluated and the effect of concentration and type (hydrophilic and hydrophobic) of NS on the morphological, mechanical, sealing, barrier and overall migration properties of PCPP films was studied.
Abstract: The food industry has a current challenge of increasing the recycling of post-consumer plastics to reduce plastic waste towards a circular economy, especially flexible polypropylene, which is highly demanded in food packaging. However, recycling post-consumer plastics is limited because service life and reprocessing degrade their physical-mechanical properties and modify the migration of components from the recycled material to the food. This research evaluated the feasibility of valorization of post-consumer recycled flexible polypropylene (PCPP) by incorporating fumed nanosilica (NS). For this purpose, the effect of concentration and type (hydrophilic and hydrophobic) of NS on the morphological, mechanical, sealing, barrier and overall migration properties of PCPP films was studied. Incorporating NS improved Young’s modulus and, more significantly, tensile strength at 0.5 wt% and 1 wt%, where a better particle dispersion was confirmed by EDS-SEM, but it diminished elongation at breakage of the films. Interestingly, NS tended to increase the seal strength of PCPP nanocomposite films more significantly at higher NS content, showing a seal failure of the adhesive peel type which is preferred for flexible packaging. NS at 1 wt% did not affect the water vapor and oxygen permeabilities of the films. Overall migration of PCPP and nanocomposites exceeded the limit value of 10 mg dm−2 allowed by European legislation at the studied concentrations of 1% and 4 wt%. Nonetheless, NS reduced the overall migration of PCPP from 17.3 to 15 mg dm−2 in all nanocomposites. In conclusion, PCPP with 1 wt% of hydrophobic NS presented an improved overall performance of the studied packaging properties.
