“…Massive consumption and improper disposal of single use PPE can result to considerable generation of plastic waste, with plastics accounting for more than half of their weight (Singh et al 2020 ). The primary methods for PPE waste disposal, landfilling and incineration, exert considerable burden on the PPE waste management system (Lyu et al 2023b ). Furthermore, certain amount of PPE waste is discarded directly into the environment rather than being disposed in landfills or incineration facilities.…”

The unprecedented surge in the demand for personal protective equipment (PPE) worldwide during the covid pandemic resulted in a significant increase in PPE consumption and subsequent waste generation. Despite the importance of PPE, its widespread usage and disposal have sparked worries about the environmental impact and its long-term sustainability. The increasing awareness of environmental challenges, resource scarcity, and the urgent need to mitigate climate change necessitates a paradigm shift in the product design, manufacturing process, and waste management of PPE. To address these challenges and have a sustainable PPE future, the development of degradable polymers and natural fibers offers a promising alternative to traditional plastics. Additionally, recycling and upcycling methods can convert the waste into valuable alternate products or energy sources, thereby reducing their environmental impact. Better waste management systems, comprehensive policy frameworks, and international collaborations are essential for the effective PPE waste management and the promotion of sustainable practices. Despite the challenges, collaborative efforts across governments, manufacturers, research institutions, and waste management authorities are crucial for transitioning to a more sustainable PPE industry and a circular economy, ultimately benefiting both the environment and society.

“…Since decades ago, thermoplastics represent polymers have been widely used in many applications, which have inevitably posed challenges to the whole public health system and social environment. 1,2 As estimated, the annual trend in plastic demand continues to increase and which would release 1.2 billion metric tons plastic waste by 2050 globally, 3 causing serious environmental pollution and ecological problems. 4 With thermoplastic polymers' excellent plasticity and recyclability, using recycled polymers in more applications will help mitigate the above issues.…”

This study investigated the effects of mechanical recycling on the crystallization, mechanical, thermal, and rheological properties of recycled high‐density polyethylene (rHDPE), as well as vHDPE/rHDPE pellets and films made by different compositions. The results confirmed the presence of contaminants in rHDPEs, and the crystalline diameter of rHDPE is smaller than that of virgin high‐density polyethylene (vHDPE), with diameters ranging from 0.60 to 0.72 μm. The content of 75 wt% vHDPE in rHDPE film could repair the defects of crystalline morphology to approximate that of vHDPE films and significantly improve the elongation at break. The temperature required for the transition from crystalline to amorphous state of rHDPE film was 2°C lower than that of vHDPE, and the crystallization time and crystallinity declined compared to that of vHDPE. For rheological performance, the apparent shear viscosity and melt fluidity of rHDPE were worse than those of vHDPE. The blending of low rHDPE with vHDPE is a feasible option not only to reduce plastic waste but also to maintain acceptable properties of the blend composition.
