Abstract

Utilizing mechanical characteristics, recycling efficiency, and environmental effect as its focal points, this work explores the creation of waste utilizing recycled materials and nanofillers. The green nanocomposite has a tensile strength of 55 MPa, a Young’s modulus of 3.0 GPa, and an impact strength of 6 kJ/m^2, according to the experimental findings, which show that mechanical characteristics are greatly improved when nanofillers are added to recycled plastic matrix materials. After 9 months, tensile strength drops 10%, Young’s modulus drops 20%, and impact strength drops 25%, suggesting that mechanical qualities may deteriorate with time. An evaluation of the green nanocomposite’s recycling efficiency found that it was 90% efficient, meaning that it made good use of waste materials throughout its production. Analyses of environmental impacts show that waste have the ability to be a sustainable alternative to virgin plastic by significantly reducing their carbon footprint, water use, and land use. Green nanocomposite manufacturing with recycled materials and nanofilllers is feasible and environmentally beneficial, according to these results. This research contributes to the conservation of resource es and the concepts of the circular economy in materials science and engineering.
