“…6 Plastic debris produces heat and CO 2 when it is burned or dumped in landfills. 12 When plastic was widely used and behaviours were altered, major issues including an increase in garbage build-up resulted from these factors. When plastic waste is not properly disposed of, environmental problems which are also known as socio-environmental problems are created or made worse.…”

Plastics pose a huge threat to the environment. Plastic accumulation in the land and the seas is now the world’s most terrorising problem, mainly because of its non-degrading character. Plastic degradation has always been a next to impossible concept in the field of science, but nanotechnology provides a revolutionary and modern way to solve the problem of plastic accumulation in the environment. One of the great advantages of nanoparticles is that we can increase and decrease the rate of biodegradation depending on our needs. Nanoparticles enhance the polythene degradation capacity of the microorganisms by altering their metabolic cycles. Numerous studies showed conclusively that the incorporation of nanotechnology enhances the ability of microorganisms to degrade polythene materials. Even though bio degradable plastics are nowadays produced in large quantities to substitute polythene materials, they fail to match the brittleness of plastics. Biodegradable plastics have poor thermal, mechanical and low gas barrier qualities, which are their main drawbacks. To overcome this, nanoparticles are incorporated into the biopolymers. If an appropriate balance between nanotechnology, microbiology and biotechnology is found, plastic degradation can be done economically and feasibly in all the areas.

Microplastics are the basic particles (1 µm–1 mm), derived from degradation of polymers with maximum molecular weight via various sources. They occur in a variety of shapes and sizes, in the form of domains, particles, and fibers. Release of Microplastics in the ecosystem, due to deterioration of macroplastics are now being considered as major toxic pollutants. Accumulation of microplastics in the diverse ecosystems is known to cause severe health and ecological effects. Since it is mandatory to take steps towards the removal of microplastics through effective and safe technology, with this objective, the present study is undertaken to reveal various green technology principles for the management of microplastics contamination associated with diverse environmental sources. This strategy involves physical methods, chemical methods, biological methods that under the conventional measures and nanotechnology principles as modern remediation. Physical methods involve filtration, membrane‐technology and adsorption. Chemical remediation involves hydrolysis, alcoholysis, acidolysis, glycolysis, aminolysis, photocatalytic degradation and electrochemical oxidation resulting in decomposition of microplastics into simpler, non‐toxic end products. Biological methods involve biosorption, microbial degradation, microbial ingestion and phytoremediation, where plants or plant biomass can be used for removal of microplastics via phytoaccumulation, phytostabilization, phytovolatilization and phytofiltration. Nano technology remediation utilizes nanoscale materials as adsorbents. Due to its unique nanosize, high surface area and energy, nanomaterials are considered effective adsorbents of microplastics. Microplastics can also be detected and identified using machine learning approaches. The present study implies that, the green technology principles can be effectively utilized for the removal of microplastics associated with diverse ecosystem.

“…Improper use of plastic waste in Third World Countries, like burning it, as in several parts of Asia and Africa, harms the environment and people's health. Also, recycling plastics is challenging because of money issues, not sorting waste well, using lots of energy, mixing it with other stuff, and cleaning problems [54]. Thus, in recent years, there has been an increased focus on reducing plastic waste generation, promoting and developing more sustainable alternatives to plastics, and aiming to minimize the need for incineration and landfilling LDPE and other plastic waste, a key objective [55].…”

“…These are also called nanometre-scale materials, as their particle size range is 1 nm to 100 nm. For LDPE waste management, incorporating Nanoscale particles into a polymer matrix can improve biodegradability and increase the efficiency of the photodegradation process [27,28]. The addition of nanoparticles increases the surface area of the polymer, making it more accessible to UV radiation and microorganisms in the environment [29,30].…”

Plastic waste generated from the widespread use of low-density polyethylene (LDPE) has raised significant environmental concerns due to its slow degradation. This review article explores the progress in LDPE nanocomposites for photodegradation, emphasizing strategies, mechanisms, and applications. Incorporating inorganic nanoparticles like titanium dioxide (TiO 2 ), zinc oxide (ZnO), and iron oxide (Fe 2 O 3 ) into LDPE has been examined to enhance its properties and biodegradability. These nanoparticles strengthen LDPE's mechanical, thermal, and barrier characteristics, thereby improving its overall performance. Various techniques have been employed to optimize the concentration and size of nanoparticles to attain the desired properties. Photodegradation, employing sunlight to break down LDPE into smaller fragments, has effectively decomposed plastic waste and reduced its environmental impact. Artificial UV light sources and additives like sensitizers and biological agents such as enzymes and microorganisms can enhance photodegradation. The incorporation of inorganic nanoparticles in LDPE significantly improves its properties and biodegradability. Research into LDPE nanocomposites for their degradation under sunlight shows potential in addressing the environmental challenges caused by plastic waste. This advancement opens the door to a wide range of applications for LDPE nanocomposites, offering a sustainable alternative to traditional plastics.
