Abstract MPs are widely found in various environments. PS is the second most common microplastic sediments, freshwater, soil, and coastal ecosystems. S. cerevisiae was studied as a biocoagulant due to its advantages such ease of use, non-toxicity, large-scale cultivability low cost. The aim this study evaluate efficiency removing from aqueous solutions. BBD used determine optimal removal conditions. were washed, dried, crushed, sieved, kept closed container avoid exposure light moisture. measured under parameters dose (100–300 mg/L), concentration (200–900 pH (4–10). suspension stirred subjected variable speeds disperse yeast cells contact with particles. formed clots settled static conditions, suspended solution by filtering through Whatman filter paper recording weight after drying. maximum 98.81% optimized i.e., 550 mg/L, 200 7. With regard mentioned results, it can be said that natural environmentally friendly remove PS.

Plastics have conveyed great benefits to humanity and made possible some of the most significant advances modern civilization in fields as diverse medicine, electronics, aerospace, construction, food packaging, sports. It is now clear, however, that plastics are also responsible for harms human health, economy, earth's environment. These occur at every stage plastic life cycle, from extraction coal, oil, gas its main feedstocks through ultimate disposal into The extent these not been systematically assessed, their magnitude fully quantified, economic costs comprehensively counted.The goals this Minderoo-Monaco Commission on Human Health examine plastics' impacts across cycle on: (1) health well-being; (2) global environment, especially ocean; (3) economy; (4) vulnerable populations-the poor, minorities, world's children.

Due to the 'forever' degrading nature of plastic waste, waste management is often complicated. The applications are ubiquitous and inevitable in many scenarios. Current global plastics production ca. 3.5 MMT per year, with current trend, will reach 25,000 by 2040. However, rapid growth manufacture material's inherent resulted accumulation a vast amount garbage. recycling rate <10 %, while large volumes discarded cause environmental ecological problems. Recycling rates for vary widely region type plastic. In some developed countries, around 20-30 developing nations, it much lower. These statistics highlight magnitude problem urgent need comprehensive strategies manage more effectively reduce its impact on environment. This review critically analyses past studies essential efficient techniques turning trash into treasure. Additionally, an attempt has been made provide understanding upcycling process, 3Rs policy, life-cycle assessment (LCA) conversion. advocates pyrolysis as one most promising methods valuable chemicals. addition, can be severely impacted due uncontrollable events, such Covid 19 pandemic. chemical certainly bring value end-of-life LCA analysis indicated there still huge scope innovation area compared mechanical recycling. formulation policies heightened public participation could play pivotal role reducing repercussions facilitating shift towards sustainable future.

Abstract Purpose of Review The synergistic effects microplastics (MPs) and heavy metals are becoming major threats to aquatic life human well-being. Therefore, understanding interactions between MPs is crucial comprehend their environmental impacts. Recent Findings mechanisms such as electrostatic attraction, surface interactions, ion exchange, hydrogen bonding, hydrophobic forces, π–π behind the were critically reviewed justified. In addition, roles chemistry in these also emphasized. Finally, efficient remediation techniques aligning with a circular economy-based initiative promote sustainable solutions recommended mitigate plastic-heavy metal pollution achieve cleaner environment. Summary This review examines combined impact ecosystems, detailing mechanistic consequences proposed solutions. Additionally, this highlights MP-heavy contamination risks emphasizes need for further research safeguard health.
