“…[2] The negative effects of plastic trash on the environment make it a top priority to find innovative ways to or eliminate it or significantly mitigate it. [3] Conductive polymer nanocomposites offer a viable and promising solution to many of today's technological problems [2,4] ; however, only one type of polymer is currently recyclable at large scale with minimal carbon footprint associated with its process, i.e., relatively lowmelt temperature thermoplastics. Nature based (natural and bio-) polymers still have a long way to be adopted for large scale and mass production for public use.…”

A novel, zero‐waste and recycling plastic waste solution is introduced, to scalably produce graphene nanoplatelets/barium titanate (GNP/BaTiO3) polymer nanocomposite fibrils. A comprehensive investigation is performed to evaluate the compatible and non‐compatible recycled polypropylene (PP)/polyethyleneterephthalate (PET) blends combined with functional (electrical, piezoelectric,and dielectric) materials for in‐situ fibril production. The nanocompositefibrils made from recycled PP, PET and GNPs/BaTiO3 with high‐aspect ratio disparity (400:1) are produced, which exhibit significantly enhanced electrical, thermomechanical, and electromagnetic characteristics. Single‐screw extrusion is utilised to fabricate the fibrils with the in‐situ fibril morphology of PET and GNPs/BaTiO3 leading to improved electrical conductivity. It is demonstrated that such fibril morphology restricts the chain mobility of polymer molecules, and ultimately increases viscosity and strain energy. Moreover, the study demonstrates a positive reinforcement effect from the utilisation of PET fibrils and GNPs/BaTiO3 in a PP matrix, dominated by the high‐aspect ratio, stiffness, and thermal stability of GNPs/BaTiO3. Furthermore, it is observed that the mechanical properties and tension‐bearing capacity of the PP are significantly improved by such incorporation. The study also demonstrates that the protection of the remanufactured nanocomposites against electromagnetic interference is significantly improved with the increasing GNPs/BaTiO3 content and the morphological transition from spherical to fibril‐shaped PET.

“…Medical plastic waste can be converted into energy through various processes such as pyrolysis, , gasification, and incineration . However, these processes involve the heating, burning, and oxidation of plastic, which are not environmentally friendly options. − Therefore, the direct reuse of medical plastic waste can effectively reduce the amount of waste generated and minimize the environmental impact. In addition, recycling and reusing medical plastic waste should always be the top priority, as it reduces the amount of waste requiring treatment and helps to conserve natural resources.…”

This paper discusses the environmental problems posed by medical plastic waste produced in healthcare facilities and explores a suitable way to reutilize the waste through triboelectric nanogenerator (TENG) device technology. Remarkably, the study investigates the potential of medical waste saline bottles to create energy-harvesting, health-monitoring devices and tactile, humidity-sensing applications. Saline bottle sheets are used as triboelectric material to fabricate a TENG in vertical contact separation (VCS) and single electrode (SE) modes. The VCS-TENG produced a power density of 8.78 W/m2 and could power various devices, including 420 red LEDs and portable electronic devices. Sleep monitoring experiments were performed by using an implanted TENG inside the pillow. The SE mode of TENG produced a power density of 1.46 W/m2 and was demonstrated for tactile sensing applications. The present work suggested using medical waste to make health monitoring, tactile sensing, humidity sensing, and energy-harvesting devices and possible applications in touch sensors for various security applications, human–machine interfaces, and IoTs. The proposed idea of using medical waste for TENG fabrication can be further extended to other nontoxic waste plastic generated in the medical field.

“…There are various alternative ways of utilizing plastic waste that can help reduce pollution and its impact on the environment. One approach is to recycle plastic waste and use it to manufacture new products [7][8][9][10] and new functional materials. [11][12][13][14] Another option is to convert plastic waste into fuel through a process called pyrolysis.…”
