Summary: In this study, rPE based MFCs were developed by incorporating rPET and rPA as reinforcing fibrillar phases at a given weight ratio. The effects of extrusion and injection molding temperatures on fibrillar structure and properties were explored. EnBAGMA and MAH-g-PE acted as compatibilizers, refining the fibrillar structure and significantly influencing mechanical properties.

Summary: This study investigated the feasibility of recycling up to 100% of protective LDPE (rLDPE) to develop blends-based nanocomposites. The results showed improved mechanical properties and no significant differences in thermal properties and thermal aging resistance compared to virgin LDPE. This confirms the effectiveness and environmental benefit of using recycled materials.

Summary: Extrusion blow molding technology is commonly used for manufacturing plastic bottles, but less so for bottles made from environmentally friendly bioplastics. This study focused on designing PLA/PBS/micro-lamellar talc compounds for bioplastic bottles, particularly for wine packaging. The experimental results showed that these bio-derived polyester resin blends can be effectively processed through extrusion blow molding, offering potential as a low environmental impact alternative to oil-based plastics in wine bottle production.

Summary: The current global plastics economy is linear, but transitioning to a circular economy is crucial for reducing environmental impacts through degradation, reuse, and recycling. Mechanical recycling plays a key role in a sustainable plastic economy, but challenges such as high costs, mechanical property degradation, and inconsistent product quality need to be addressed.

Summary: This article prepared advanced biodegradable thermoplastic elastomer (BTPE)/reduced graphene oxide (rGO) nanocomposites using aliphatic diols, aliphatic dibasic acids, and graphene oxide (GO) as raw materials. The rGO is well dispersed in the BTPE matrix through its predispersion in aliphatic diols before the polycondensation of the polyester prepolymers. The addition of GO greatly enhances the tensile strength, elongation at break, biodegradability, and electrical conductivity of the BTPE/rGO nanocomposites.

Summary: Shredding is an important step in mechanical recycling, and optimizing the cutting process can help reduce the formation of potentially harmful fiber dust during the shredding of fiber-reinforced plastics. Adjusting parameters such as throughput, rotational speed, screen size, and feedstock size can have different effects on the amount of fine particles and fiber length distribution. The research findings provide insights for improving the eco-friendliness of mechanical recycling processes.

Summary: By synthesizing and studying a novel phosphazene-triazine bi-base sulfonate compound (CPNS), it was found that adding a certain proportion of CPNS in modified polycarbonate can significantly improve the flame retardant properties of the material and reduce the heat release rate during combustion. At the same time, CPNS can also promote the formation of more complete and compact carbon residue during the combustion of polycarbonate, further enhancing the flame retardant effect.

Summary: The study focused on the devulcanization process of EPDM rubber, finding that sulfur-cured samples exhibited good selectivity for cross-link scission while peroxide-cured samples suffered degradation. The mechanical properties of blends of EPDM rubber and high-density polyethylene were affected by the EPDM rubber content, with compounds containing originally uncured rubber mixtures having the most beneficial mechanical properties.

Summary: This paper discusses the correct approaches for small-scale mechanical recycling of solid plastic waste. Thermoplastics are primarily considered for mechanical recycling due to their physical properties and ease of reprocessing. The paper reviews the mechanical reprocessing techniques of selected thermoplastics, such as polyethylene terephthalate and polyolefins, which are widely used commercially. It also addresses the necessary considerations for effective operation and optimization of small-scale plants to improve efficiency and product quality. By understanding and addressing process-related challenges, successful small-scale mechanical recycling facilities can be established to benefit communities. Efficient small-scale mechanical reprocessing establishments are crucial for reducing environmental impacts and conserving energy.

Summary: This article investigates the impact of incorporating biofillers at 5% wt. and 10% wt. on critical polymer properties. The results show that the presence of rice hulls or coffee chaff does not significantly alter thermal and mechanical properties at 5% wt. loading, but some reduction is noticed at 10% wt. Additionally, the complex viscosity is reduced with the introduction of biofillers.
